Published scenarios often teach us that scenario hooks are a bang-bang interaction: The mysterious stranger in the corner of the tavern tells us about a mysterious artifact, hires us to go look for it, and we immediately head to the dungeon to retrieve it.

Or we’re traveling along an idyllic country road when we come across the smoking remnants of a merchant’s wagon that was attacked by goblins. The ranger finds their tracks and leads us back to their warren.

There’s nothing wrong with these bang-bang hooks. But they’re disproportionately represented in published adventures because the writers have no way of knowing what’s been happening in your campaign: Everything you need to run and play the adventure has to be self-contained in the adventure.

But as the GM, you do know what’s been going on in your campaign. In fact, you can control it. That gives you the power to easily do so much better than the author of that published scenario.

• What if, instead of a “mysterious stranger,” it’s a long-time ally or patron of the PCs? Someone they’ve built a relationship with.
• What if instead of fetching an artifact that an NPC wants, the McGuffin is something that the PCs need to accomplish their goals? Maybe the stranger isn’t buying their services, but selling them information.
• Instead of a random merchant, what if the goblins attacked someone the PCs know and care about?
• What if the goblins don’t just materialize out of thin air, but are a threat people in the local village have been talking about for weeks? Or are part of a goblin clan that the PCs have fought before?

These kinds of long-term threads will weave the adventure into your campaign. The stakes will be higher, and more meaningful to the players, because they aren’t just transitory concerns.

Long-term scenario hooks can be implemented in a variety of ways (and have a variety of effects) depending on the campaign structure you’re using, but for the sake of simplicity let’s focus on episodic campaigns for the moment — the players are presented with a single scenario; they complete the scenario; then they get presented with the next scenario.

Broadly speaking, there are two ways to implement long-term scenario hooks. First, you can retrofit the hook. When you pick or design your next adventure, you simply look back at the campaign to date and figure out how to use the existing continuity to hook the new adventure. What are the PCs trying to accomplish? What do they want? Who do they care about? Who do they hate? What are your players talking about between sessions? Just dangle it on the hook.

The other option is to plan for the hook. Which is basically what it says on the tin: If you know what adventures you’re planning to run later in the campaign, take a peek at them and think about how you can incorporate and foreshadow those elements into the earlier adventures of the campaign.

EXAMPLE: JOURNEYS THROUGH THE RADIANT CITADEL

SPOILER WARNING

As an example of what this prep might look like, let’s take a peek at Journeys Through the Radiant Citadel. This adventure anthology, shepherded into existence by project leads Ajit A. George and F. Wesley Schneider, is a collection of thirteen D&D 5^th Edition adventures designed for PCs from 1^st level through 14^th level. Although loosely bound by the conceit that the adventures are set in a location which can be reached via the transplanar nexus of the Radiant Citadel, each adventure is a completely standalone experience.

Nevertheless, it seems quite likely that many DMs will run Journeys Through the Radiant Citadel as an episodic campaign, running each adventure in sequence, one after the other.

So how could we prep long-term scenario hooks for these adventures?

To start with, the tiers of play in D&D 5^th Edition make for a handy rule of thumb here: To set yourself up for success, you should be dropping the groundwork for your Tier 2 and Tier 3 adventures in the Tier 1 adventures of your campaign.

The Tier 1 adventures in Journeys Through the Radiant Citadel are:

• Salted Legacy, in which the PCs get caught up in family drama and business rivalry in the Dyn Singh Night Market.
• Written in Blood, in which the PCs journey to a farming commune to uncover the source of an undead curse.
• The Fiend of Hollow Mine, in which the PCs must hunt down a demon-spawn which has unleashed a plague in San Citlán.

Using these scenarios as the foundation for our campaign, let’s take a look a the scenario hooks for the next several adventures in the anthology. One of the great things about Journeys Through the Radiant Citadel is that the designers have included multiple scenario hooks for each scenario, so we’ll have some nice flexibility in what we can work with.

Wages of Sin includes this scenario hook:

Zinda’s March of Vice is famous throughout the region. An influential ally of the characters requests that they attend and, while they’re there, purchase a bottle of jeli wine to be used as a gift in a diplomatic negotiation.

Let’s go back to “Salted Legacy.” The ally requesting the jeli wine purchase could actually be Lamai Tyenmo, the owner of Tyenmo Noodles who hired the PCs. But let’s also find ways of pointing forward: At the end of “Salted Legacy,” perhaps Tyenmo asks the PCs to keep their eyes open for interesting ingredients and drinks that she might use to create new noodle dishes and enhance her menu. (That’s a nice, open-ended link, because it’s quite likely the players will find ways to continue engaging with it in every adventure. “Hmm… I wonder aurumvorax steak noodles would taste like?”)

In “Wages of Sin,” the PCs get involved with Madame Samira Arah, a King of Coin (one of the rulers of Zinda), and her investigation into a series of attempted political assassinations. It might be nice to pre-establish her. If we reach back to “Written in Blood,” one of the hooks is:

A trader the characters have had past dealings with — perhaps from the Radiant Citadel or the Dyn Singh Market — invites the characters to Promise to participate in a business deal with Aunt Dellie.

We’ll have this merchant be Samira Arah. She’s been doing some economic outreach and the guards she had with her took ill after their visit to San Citlán. One of the merchants from “Salted Legacy” recommended the PCs to her, and she contacts them in the Radiant Citadel.

Sins of Our Elders takes place in Yeonido during the week-long Dan-Nal Festival. One of the hooks involves the PCs being invited to attend the festival by a family member or friend. You can look to the PCs’ backgrounds for the family member or friend (who might be native to Yeonido or might just want to visit), but we can add a little foreshadowing by having Samira Arah mention in “Written in Blood” that her next festival envoy will be to Yeonido.

Gold for Fools and Princes takes place in the Sensa Empire, where the empire’s rich gold mines are disrupted by an infestation of gold-eating aurumvoraxii. The big thing we’d really like to pre-establish here is the Empire’s reputation for goldsmithing and the powerful Aurum Guild. This should be fairly easy: Lady Drew, the trader from “Written in Blood,” can try to sell the PCs Sensan gold. In “The Fiend of Hollow Mine,” some of the miners who worked in the now-abandoned mine can talk about traveling to Sensa to see if they can find work with the Aurum Guild.

Trail of Destruction brings the PCs to Etizalan, where an increase in volcanic activity is threatening settlements across the region.

The Shieldbearers of the Radiant Citadel [think fantasy UN Peacekeepers] hire the characters to visit Tletepec to verify rumors that the region is becoming dangerous, so that they can prepare for an influx of refugees. They suggest the PCs start their investigations near Etizalan.

Here we want to pre-establish the Shieldbearers. We can do that by having them question the PCs after end the regional plague in “The Fiend of Hollow Mine.” We could also add a small squad of Shieldbearers active in the region — trying to bring aid to the plague victims — that the PCs could encounter earlier in the adventure.

And that’s more or less all there is to it. Obviously, you could also continue weaving these threads through the later adventures. For example, if the PCs are getting on well with Samira Arah, she might send them to the Goldwarrens on some errand as the primary scenario hook for “Gold for Fools and Princes.”

FOR THE DESIGNERS

Although I opened this discussion by saying that published adventures were predisposed to bang-bang hooks and that it’s impossible for adventure writers to know the continuity of the campaigns of the GMs who choose to run the adventure, it’s NOT true that you can’t design long-term scenario hooks for published adventures.

The trick is to simply prep tools and content that GMs can use before your adventure begins.

A tool I’ve developed in my work as a designer are groundwork sidebars. (These are one of several scenario tools you can used in published adventures.) Groundwork sidebars give the GM examples of how material can be incorporated into earlier adventures; it’s literally laying the groundwork for the adventure.

You can find numerous examples of this in the Welcome to the Island adventure anthology for Over the Edge, for example.

Advanced Gamemastery: The Campaign Stitch

Techniques like the Three Clue Rule and node-based scenario design can make mystery and conspiracy scenarios a joy to run and play with confidence. These structures are designed to make sure that the players get the information they need to understand complicated enigmatic situations, while also being empowered to make meaningful choices about what they want to do.

But what happens if they forget they have the information?

This generally isn’t a problem in a short scenario or one-shot, but it can be easy to lose track of stuff between sessions. And if a campaign is focused on unraveling a massive conspiracy, the investigation might span months or even years of time in the real world.

Now the Grade-A solution for this is to have at least one player in your group who is engaged, enthused, and rigorously keeps detailed notes. They’ll backstop the rest of the group and make sure fine details don’t get missed.

But while there are things you can do to encourage or even create players like that, not all of us will be so blessed. And there are also a lot of reasons why it’s good to get as much of the group up to speed as possible.

I’ve previously talked about how one of the most potent tools in a GM’s arsenal is a simple question:

What are you planning to do next session?

Because it allows you to focus and target your prep with confidence.

But before asking that question at the end of a session, first ask the players to briefly summarize what they feel their current options are: What do they know? Where do they think they could take the investigation next?

THEN ask them what they want to do next time.

This is the best time to do this, obviously, because the game is still fresh in their minds and they’re engaged in the moment. Take notes on what they say. At the beginning of the next session, ask them to recap the previous session and use the notes of what they said to fill in the gaps.

The best way to do this is as a discussion: Prompt them to provide what they recall, then fill in the gaps as they come up with what their former selves said but they’ve forgotten.

There are a couple reasons for doing this. First, the act of summarizing what they know and what they plan to do at the end of the previous session will, all by itself, improve their recall in the next session. Second, it makes it less likely that you — biased by your own knowledge of what’s important and what the correct conclusions are — will unconsciously put your thumb on the scale when summarizing things for them.

If you make this procedure habitual, it also becomes increasingly likely that the players will start jotting down these notes themselves and possibly even reviewing them between sessions.

(You can prompt this a bit by initiating an e-mail discussion on this stuff a few days before the next session, although this does carry the risk that the players will change their minds about what they want to do next, possibly misfooting your prep.)

TAKING NOTES

Here’s something else to note. Take a look around the table: The players have pencils. They have characters sheets. You may be surprised by how often they don’t actually have any spare paper to actually take notes with!

Provide them with that material. Something I like to do is to buy the players some cheap (but ideally flavorful) pocket notebooks and hand them out in the first session. (For example, stamp TOP SECRET! on the cover for a spy game. Or print a map of the game world and paste it to the cover.) It’s a nice little campaign gift, and also sends a message that they’re going to want to take notes in this campaign!

Another technique you can use is to reward players who prepare campaign journals. (This both encourages note-taking and also creates a shared document that can be referenced.) With receptive players, you can lean into this and create rich bluebooking for the campaign. (I discuss bluebooking in more detail here.)

You can also bypass note-taking entirely by encoding essential clues into props: Letters, business cards, photographs, maps, lore books — whatever you’re comfortable executing. Putting the clue into a physical item that you hand to the players creates a permanent reference. They no longer need to remember the clue; they can pick it up and look at it again at any time.

When a PC dies, their player is left without an avatar to interact with the game world. This means that they can no longer play the game, and are forced to simply sit and wait while everyone else keeps playing.

This is not necessarily a terrible thing. There are many players who thoroughly enjoy the audience stance and can have a grand old time being entertained watching their fellow players trying to haul their corpse back to civilization for a raise dead spell (or seeking bloody vengeance for their death, whatever the case may be). But, generally speaking, you don’t want the players of a game to be in a position where they can’t play the game.

In Random GM Tips: Backup PCs we discussed a variety of techniques you can use to shorten the amount of time players are in this purgatory. But there will likely still be spans of time when they’re twiddling their thumbs.

So what can you do?

Have them assume the role of an NPC. This character might be an ally or companion of the PCs, in which case the role become sort of a temporary PC, but it doesn’t have to be. It’s quite possible for players to step into any supporting character or even assume the role of foes.

IN COMBAT

A fairly easy time to do this is during combat: A fight breaks out, you hand the idle player one of the monster’s stat blocks, and you ask them to roll for initiative.

It’s just that simple. They might be playing for the other “team,” but they’re actively playing the game. (And if the monster they’re controlling gets killed, you can always pass them the stat block of another.)

Combat can often be the most time-consuming — and also the least interesting if you’re not actively participating — part of play, so keeping a player engaged during these encounters can solve most of the problem all by itself.

There are a couple things to consider here. First, what if the player sandbags the encounter for the benefit of the other PCs? Ideally you have a player who can embrace the challenge, but if this is a concern simply give them an ancillary stat block instead of the central bad guy in the encounter.

Second, what if the player goes all-in and ruthlessly takes down the PCs? This becomes an issue if you’re designing encounters that are too difficult and then dumbing the NPCs down so that they don’t crush the PCs. The short version is that you should stop doing that. But if this is a concern, then you may want to rethink using this technique (or, once again, give the player a less power member of the encounter that’s less likely to go PC stomping).

These minor concerns aside, the reason this works so well is that:

• Monster stat blocks are designed to be picked up and played.
• The monster’s agenda in combat is so straightforward (defeat the PCs) that it probably doesn’t even have to be explained in words.

So it’s very easy for the player to grab the monster and jump straight into play.

IN ROLEPLAYING

We can learn from lessons from this as we consider how a dormant player can successfully step into an NPC’s role in other scenes.

The first thing we would need is a briefing sheet (similar to a monster’s stat block) that can be handed to the player and bring them up to speed on everything they need to know about the NPC. Fortunately, if you’re using the universal NPC roleplaying template, it basically solves this problem.

The second thing we need to do is clearly communicate to the player what the NPC’s agenda is. Outside of combat this can get quite complicated and/or nuanced, but you don’t want to spend a lot of time briefing the player in (which kind of defeats the purpose of keeping everyone involved, can wreck the pacing, and can easily overwhelm and stress out the player). Try to select roles with simple, straightforward agendas (like, “you need to make sure Old Bill tells the PCs that he saw Murray by the shed at 1 A.M. last night”). These might even be conveniently summarized in the Key Info section of the roleplaying templates (neatly killing two birds with one stone).

Take advantage of these moments, too. For example, it’s always challenging for the GM to stage a scene where multiple NPCs talk to each other. But if an NPC is being played by a player, suddenly the NPCs can have a true conversation at the table!

BUT THAT’S NOT ALL…

This technique also works even if the PC isn’t dead. Maybe they’re imprisoned, in a coma, in flagrante delicto, or simply across town staking out the warehouse belonging to the Quicksilver Corporation. Whatever reason the PC might have for not being in the current scene, you can bring the player into the scene through the supporting cast.

It can also be used for new players, who might assume a supporting role at the beginning of their first session until you can arrange for their character to join the group. An extreme example of this, for me, was a Trail of Cthulhu campaign in which the group was on an expedition in the middle of a trackless waste. The new player assumed the existing role of an NPC guide and, due to an unforeseen swerve in events, ended up playing this character for several sessions before their own character could be brought into the ongoing events.

In another case, during the first session of a campaign, the players had set things up so that their new characters would meet each other when a caravan arrived in a new town. (Some of the characters would logically be with the caravan, and others would be in town.) But, for various reasons, I wanted the caravan to be attacked on its way to town. Rather than leave half the group dormant, I immediately handed them the monster stat blocks and had them plan out the ambush on the caravan.

When using this technique, particularly with the not-so-deceased, you may want to keep one eye on spoilers. Make sure your NPC briefing sheets don’t contain sensitive information that the PCs/players shouldn’t have access to yet. You may also find that some players really WOULD prefer to remain in an audience stance rather than splitting their attention into a new role. Try to be aware of that and respect it.

Roleplaying games can vary a lot in how lethal they are for player characters. And, perhaps even more importantly, they can vary a lot in how permanent death is when it occurs.

This can even be true within a single system. In some classic versions of D&D, for example, PCs can begin in an ultra-fragile state (in which any hit in combat could automatically kill them) and then level up to a point where death is just a minor inconvenience.

But let’s assume that we’re playing a game where death really is the final frontier: If your character dies, then they’re dead. No take-backs. If you’re playing in a campaign with a game like that, how can you handle death?

One way is to duck the question entirely with script immunity. In campaigns with script immunity, PCs simply can’t die. This may be a feature of the rules (as in Magical Kitties Save the Day), but is often a metagame conceit openly or silently respected by the table. There are a number of techniques that are useful for making script immunity work, but the two most common approaches are to either disallow the mechanical outcome of death (NPCs will always miss the final blow) or to interpret the mechanical outcome of death to mean something other than death (e.g., the PC is instead knocked unconscious). These are often combined with a caveat which allows the PC to die if their player wants it to happen. (This is because script immunity is usually a technique favored by dramatists, and being able to have death occur only when it is dramatically appropriate and satisfying is desirable. But I digress.)

What I actually want to focus on is not how to avoid PC death, but rather what comes next.

The first option is to actually remove the player from the campaign. The PC was their agent in the game world. Now that their agent has been destroyed, they have no ability to participate in the game.

This is, in some ways, the opposite extreme from script immunity — where immunity completely removes lethal consequences from the game, the all-or-nothing approach makes those consequences about as meaningful as they can be. On the other hand, script immunity and one-PC-only both recognize how momentous and important death can be to a narrative and simply emphasize it in radically different ways.

Personally, I’ve never seen one-PC-only used in a multi-session campaign. (And I could only really imagine doing so if it was very deliberately the focus of experimental play.) But it’s far from unheard of to see it used in one-shots, and it can be built into games like Ten Candles and Dread.

The far more common approach, of course, is to replace the player’s PC with a new PC. Your character is dead, so create a new one that can join the group.

BACKUP PCs

There are two impediments to consider when using replacement PCs.

First, the time required to create the new character. This can range from trivial in some systems to laborsome to baffling (in games which feature interconnected character creation mechanics but neglect to account for how new PCs could be added to the group).

Second, how to organically integrate the new PC into the existing group. Even when the group leans into the metagame conceit of the replacement (“we trust this newcomer implicitly because we know Mark is playing her”), there can still be the question — when the group is in the middle of a vast dungeon or lost in the untracked wastes of an uncharted jungle — of how and when this new character can actually show up.

Sometimes these two problems can nicely cancel each other out (the time taken to create the new character neatly covers some or all of the time it takes the rest of the group to reach a point where a new character can be naturally introduced), but there can still be logistical and logical hurdles to clear.

The core tip here is that you can solve the first problem by preparing a backup PC. In other words, before your character dies you can already have the replacement character prepared and ready to go. This obviously simplifies things, as you can simply pull out the new sheet and get back to playing lickety-split.

Tangential Tip – Inheritance: If you’re playing in a game where gear is important (e.g., D&D), make sure backup PCs don’t come fully equipped for their current level. You need to work from the assumption that they will either directly or indirectly inherit the wealth/gear of the PC they’re creating. Otherwise every dead PC becomes an incredibly rich looting opportunity and death, rather than being a failure to be avoided, paradoxically becomes a payday which dramatically rewards the group.

You can extend this technique to begin addressing the second problem by giving the backup PC a clear connection to the group. This will often be through the PC who died. For example, “I heard my brother was killed! I have come to avenge them!” (Early versions of D&D actually included rules and guidelines for handling PC-to-PC inheritance and probate.)

BEFORE YOU DIE

Now that you have a slate of backup PCs waiting to step up if a current PC should die AND those backup PCs have existing relationships with the PCs (sisters, apprentices, old college roommates), you can incorporate the backup PCs into the game while the current PCs are still alive.

In many ways, this just makes sense. If you’ve prepped an apprentice who can replace your character Obi-Wan if they die, it makes sense that the apprentice would be part of the story before Obi-Wan’s death.

Of course, once a backup character comes onstage like this, it’s certainly possible that the evolving narrative will make them unavailable or inappropriate for being a PC. That’s fine. (Obi-Wan survived long enough and things went crazy enough with their apprentice that they ended up giving the apprentice a son and just copy-pasting their stat block onto it.)

Tangential Tip – Promoting NPCs: You can flip cause-and-effect here by letting a player of a dead PC take on the role of an established NPC. Even though the NPC wasn’t intended to become a PC, they have an existing relationship with the other PCs and are already integrated into the narrative.

Onstage backup PCs can be played by the GM, but it’s often more effective if the player takes on the role “prematurely” when necessary. To that end, it can be most effective for your backup character to have a connection to a different player’s PC. If you’re playing your own apprentice, there’ll be lots of moments when you’d have to roleplay with yourself (which can lead to skipping or abbreviating those scenes). But if you’re playing Alejandra’s apprentice, then you’ll both be able to frame up interesting scenes and small interactions that will enrich the game.

A variation of this is to create a common pool of backup characters, rather than having each player create their own. You might have one or two or three such characters, and whichever player’s PC dies first (if any) simply grabs whatever character is most convenient from the pool.

These backup characters might also just be temporary roles, which can be played until it’s convenient to create and bring in a fully fledged new PC. (In old school D&D, taking on the role of another player’s hireling is an informal version of this.)

These backup PCs can even account for Total Party Kills (TPKs). “So-and-so has mysteriously vanished/been killed and I’m looking through their notes” is a well-established trope in Lovecraftian fiction, for example, and can easily be transferred to other genres. Laying the groundwork for this sort of insurance policy can be used to frame epistolary play and bluebooking, encouraging note-keeping and enabling different forms of roleplaying that greatly augment a campaign.

You also don’t have to wait for a PC to die in order to swap to your alternate PC. Any number of circumstances might suggest it: Your primary PC might want to retire, be called away on a family emergency unrelated to the main thrust of the campaign, disappear into the Fairylands, or go into a witness protection plan. Or maybe you just want to switch things up.

In fact, you can swap back and forth between your PCs. Or across multiple characters. If your group has established a common pool of PC options, you might even find yourself playing the same character that was previously played by a different player.

TROUPE PLAY

… and we’ve just reinvented troupe play.

First created by Jonathan Tweet and Mark Rein*Hagen in the Ars Magica roleplaying game, troupe play can be broadly defined as a campaign in which the cast of player characters is larger than the number of players and the expectation is that the players will take on different roles for each session or scenario.

This style of play is, of course, quite impervious to the question of, “What does Naito do when his PC dies?” because it has already eschewed the one-to-one relationship between player and PC. More importantly, however, troupe play techniques unlock a lot of unique opportunities at the game table.

Most notably, the constant shuffling of the current group creates a huge variety in personal dynamics and relationships. (You can get a similar dynamic with an open table. The distinction here is that you can get the same effect with a small, dedicated group of players who are sharing all of the experiences in common.)

Ars Magica notably uses the technique to create the dynamic found, for example, in The Hobbit: Gandalf is clearly a much more powerful character than everyone else in the adventuring party. Ars Magica solves the problem of, “Who gets to play Gandalf?” by letting everyone create their own Gandalf and then rotating who’s playing Gandalf and who’s playing the motley assembly of mortals each week.

Similarly, a Star Trek-style space opera can run into the question of, “Who gets to be the captain?” In troupe play, the captain could be a communal character shared by all the players (each of whom also has another bridge crew member as a PC). Each session, a different player gets to play the shared role of the captain.

Ars Magica also associated the concept of a rotating GM into troupe play. I think of this as actually being a distinct technique, but it does combine very well with troupe play. (Since the campaign dynamic already has characters constantly swapping and realigning, it’s easy enough for each GM to have their characters skip the adventures that they’re running.)

One of the GM’s most fundamental skills is description. The GM’s words are, after all, the players’ window into the game world. While some performance-enhancing work-arounds do exist (pictures, miniatures, maps, etc.), the bulk of the heavy-lifting boils down to what the GM says and how they say it.

I’ve given general tips for crafting effective descriptions in the past, but if you’re looking to boil things down to some basic procedures, here are some simple formulas. (Our goal here will be to create descriptions that are efficient, effective, evocative, and also easy.)

DUNGEON ROOMS

For a dungeon room:

1. List every notable thing in the room and its position. (“Notable” here can be broadly understood as “thing the PCs will interact with / check out / will inform their actions.” Check out The Art of the Key if you want to delve deeper here.)
2. Use the Three of Five rule by dropping descriptive tags on some or all of the notable things. (In short: “Think about your five senses. Try to include three of them in each description.”)
3. If appropriate, add a verb. (Add action to the scene; e.g., instead of “there is a waterfall,” there is “a waterfall tumbles down the far wall.”)

For example, a room has:

• wardrobe
• bookshelf with arcane tomes
• a goblin

Use the formula to generate:

A horrid stench [smell] emanates from a wardrobe off to your left. On the opposite side of the room, there’s a bookshelf stuffed full [sight] of thick tomes and tightly wrapped scrolls. There’s a goblin pawing through the books on the shelf, knocking them to the ground [verb]. Seeing you, the goblin gapes its maw and screeches [sound].

NONPLAYER CHARACTERS

Whether improvising an NPC on the fly or prepping a Universal NPC Roleplaying template, you can use this formula:

1. An action.
2. What are they wearing?
3. One physical trait.

For example:

Lady Silva is wearing a beautiful blue dress [clothing] that compliments her sapphire eyes [physical trait]. She taps her finger thoughtfully on her chin while looking you up and down [action].

When using the Universal NPC Roleplaying Template, the NPC’s action may be drawn from the Roleplaying section of the template (i.e., the action may be the NPC’s common mannerism). But it doesn’t have to be. The key thing is that you’re establishing the NPC as someone living in the game world; you’re not describing their headshot, you’re establishing them in the scene.

MONSTERS

When encountering a monster:

1. Look at their abilities and attacks; describe how one or more of those are physically manifest.
2. Describe one non-ability-based physical trait. (Use ability scores as inspiration if you’re coming up dry.)
3. Add a verb.

Let’s pick some monsters at random and see how this plays out.

Hill Giant. They have a greatclub and a rock attack. Include the club in the description. You might mention that they’re standing near a pile of rubble (from which you can later describe them snatching up rocks to throw at interlopers). They’re a giant, so… they’re quite tall. (You don’t have to make this complicated.) What are they doing? Gnawing a bone, scratching their head, chatting amongst themselves, swatting giant flies swarming around their head? (Again, you don’t have to be particularly clever. Establish the idea and move into the scene.)

Revenant. One of their abilities is Vengeful Glare, so describe them as having eyes that burn with an eerie blue light. It’s undead and has 18 Charisma, so we can add that it’s an incredibly handsome figure with chalky gray-white skin. Simply add an action appropriate to the current scene.

(As with our other formulas, don’t get hung up on the order here. The description of the revenant, for example, can be: “A dark figure perched atop a rocky promontory, gazing out across the valley. The man’s features are handsome, but its eyes burn with an eerie blue light and its skin is a chalky gray-white.”)

Xenomorph. Their acid blood won’t be immediately obvious, but perhaps we could riff on the idea of bodily fluids by having their jaws slavering with some alien fluid. Their serrated tail whips back and forth, while the flickering fluorescent lights gleam off their black, chitinous exoskeleton.

A WORD ABOUT FORMULAS

Formulas are… well, formulaic. They’ll only take you so far, they can easily become repetitive, and it’s trivial to find examples where the generic formula will be a poor fit for the material. The role of these formulas is not to be the be-all or end-all of RPG descriptions. But if you’re stuck, you can use them as simple recipes to get your brain churning. In fact, you’ll often find that starting with a formula will quickly inspire you to spin out of the mold and create something completely different.

If it does?

Mission accomplished.

PERSISTENT DESCRIPTION

As you’re looking to expand beyond the simple formula, one thing to keep in mind is that description should persist throughout a scene.

I’ve mentioned in the past that the legacy of boxed text can condition GMs to think of description as something you only do at the beginning of a scene or when the PCs enter a room. But that’s an artificial limitation of published modules that you should try to move beyond as you’re running the game.

Add sensory details. You mentioned that there was broken glass on the floor [sight], but as the PCs move into the room you can add the description of the grass crunching under their boots [sound and touch]. The waterfall was described as roaring [hearing], but you can build on that by mentioning the cool mist it throws up [touch] or the fractured reflections of light dancing across the walls of the cave [sight].

Investigate to find new details. When the rogue heads over to check out the wardrobe, take the opportunity to describe the intricate carvings on its doors. After seeing Lady Silva for the first time they grab their drinks and head over to talk to her, and you can take the opportunity to add the color of hair as she turns to look at them.

In the case of a keyed dungeon room, this can actually be structured and prepped. Remember how we listed each notable thing in the room? When the PCs go to investigate or interact with a notable thing, that action simply triggers additional details.

Discover new things. In addition to finding new details about things you already know, the PCs may also discover entirely new things in the environment as they explore it. (What’s inside the wardrobe and causing that terrible smell?) Matryoshka techniques can be a powerful way of running this.

Introduce new elements. A cold wind blows through the cracked window. An otyugh shambles through the door. A police siren wails past the apartment building. A flickering hologram manifests in the center of the chamber. You don’t have to wait for the PCs to investigate to add something new to the scene. The world is a dynamic and active place.

Combine. All of these methods can be used in conjunction. Someone throws a rock with a note wrapped around it through the window. As Bryan goes to pick up the rock, describe the crunch of broken glass under his feet. The rock itself is black obsidian. As he pulls off the note, describe the texture of the vellum.

An image I find particularly evocative is to think of the description of the game world as being layered. You don’t have to exhaustively describe every single detail of an environment in one big glob of exposition. Make sure that the players have the key information they need to orient themselves and understand what’s happening; but then either peel back or add on (whichever visual analogy works better for you) additional layers of description as the scene plays out, slowly building up the mental image of the place like a painter laying down paint on their canvas.

EVOLVING MONSTER DESCRIPTIONS

Speaking of layers, here’s an extra tip when it comes to describing monsters.

The first time the players encounter a monster, you need to establish the monster’s basic visual image. (And you can use the formula described above to do that.) Once the players are familiar with a monster and are able to put a name to it – goblin, gelatinous cube, blood terror, little fuzzies, etc. — you don’t need to re-establish the monster’s basic description each time.

However, this can lead you into the trap of replacing evocative description with bland labels: “You see six goblins.”

What you usually want to do instead, once the players know what a monster is (when you can say “it’s a worg” instead of describing the worg), is to dig one layer deeper by customizing the monster.

These aren’t just six goblins; they’re six goblins dressed in opera dresses. This isn’t just a worg; it’s a worg with a bright red scar over its left eye. This yeti’s fur is matted and filthy. This ogre’s hair is tied up in a topknot. This ghoul’s left arm is broken; it’s hand flopping back and forth on a loose flap of sinew. This wraith wears an iron crown of Angorak.

When the PCs run into a mob, you don’t need to customize every single one of them. (And it’s usually counterproductive to do so.) As a rule of thumb, you’ll want to either customize one of them (it’s a group of yetis, and one of them is wearing a sapphire amulet) or focus on what’s notable about all of them (all of these yetis are missing a finger on their left hand).

(If you’re making one member of a group stand out, it will often be the leader. But this isn’t necessarily true. For example, one worg out of the pack might be limping and ostracized by the others.)

For humanoids, you might use the full formula for an NPC described above. But for monsters you often just need one salient detail to distinguish them.
