SPOILERS FOR DRAGON HEIST

Matu67 asks:

I’m running Waterdeep: Dragon Heist (Alexandrian remix), and I’m wondering: How do you improvise sources of information?

For example, a faction knows that character X did Y, but the DM hasn’t written down the reason why the faction knows this. When the players ask the faction, “How did you come across this piece of info?”, what do I say as the DM?

In Dragon Heist, for example, the Cassalanters know that Dalakhar was carrying the Stone of Golorr, and the DM is encouraged to give this information to the PCs if the PCs ally with them. Then the PCs ask, “Hey, Cassalanters, how do you know that?” And then I freeze up.

We can start here by getting down to the most basic ontology of the question:

How do we know things?

In this case, how does a faction in an RPG scenario — like the Cassalanters — know stuff? Where does that information come from?

Well, broadly speaking, they will have agents. (In an espionage campaign like Dragon Heist these might be literal secret agents, but generally we just mean anyone who’s a member of the faction or working with the faction.) For a faction to “know” something, it means that these agents will have either witnessed it directly or they’ll have learned the information from someone who did.

For example, “How do you know the Potenska Apocrypha can be found in the Ebon Library?”

Either someone saw the book in the Ebon Library themselves, or they’ve spoken to a scholar / read a reference to the Apocrypha in another book / cast a commune spell and been informed by the gods that the book is there.

To forge that connection, start with; Who definitely knows about the thing you’re trying to source?

For example, who knows that Dalakhar has the Stone of Golorr? Well, Dalakhar, obviously. But also, since he stole the Stone from Xanathar, members of Xanathar’s gang would know.

Who knows that the Potenska Papers are in the Ebon Library? Well… librarians, right? And probably other scholars who have seen it there? (To this general list, you could potentially also add any specific NPCs who you know have visited the Ebon Library.)

At this point, you have two options for creating the data trail.

First: If it’s possible the agents could have directly witnessed the information, then problem solved. You’re done. (e.g., “When I visited the Ebon Library, I saw the Potenska Papers in their collection.”)

You can flesh this out by providing an explanation for why they were there. (e.g., “When I was at the Ebon Library researching a summoning ritual for Demogorgon, I saw the Potenska Papers in their collection.”) The great thing is that, in an espionage scenario, you can almost always default to “…because they were spying on them” as the explanation. (e.g., “Our spy in Xanathar’s hideout was there because they were spying on Xanathar.”)

Second: If agents couldn’t have directly witnessed the information, then you just need to connect the agents to the people who do.

In some cases, it will be easier – or more fun! – if you imagine this happening in multiple steps. (For example, X talked to Y and the conversation was overheard by Z. Or the Iranian Ministry of Intelligence intercepted communication between a US Senator and the Lytekkas Corporation, which was scooped up from a vulnerable server during a Mossad operation, and we grabbed it from them because we’ve got a worm installed in their Tel Aviv data center.)

But you don’t usually need to over-complicate it. A single step is usually more than enough.

For example, “We have an informant in Xanathar’s gang, and he was sent out as part of a team to find Dalakhar and retrieve the Stone.” Or, “One of our agents intercepted written orders that were sent to Xanatharian agents to be on the look out for Dalakhar and to retrieve the Stone he carried.” Or, “I hired a Sage of Orthoria to research the Potenska Papers, and they found a reference to a copy that was given to the Ebon Library.”

If the players want to dig even deeper – e.g., “Who is this agent?” – an espionage campaign usually gives you the luxury of waving them off. (“Their identity is confidential. I’m sure you can understand that revealing it could potentially put them in danger.”)  On the other hand, there’s often no harm in satisfying their curiosity: If you know who the agent is, great If not, then it’s time to reach for your list of NPC names and spin somebody up.

This may also be a good point to figure out why the players are so insistent about digging into this data trail. (This is a slightly hidden case of making sure you know the intention of an action before resolving the action.) For example, maybe they want to question the Cassalanters’ informant; or maybe they just want to make sure they don’t accidentally kill them when they raid Xanathar’s hideout. Maybe the reason they want access to the original Tel Aviv intercept is because they want to run a data analysis and see if they can identify the location of the IP address the message was originally sent from.

Once you know what they’re actually looking for, it becomes a lot easier to aim your improv.

The way to do this, of course, is to simply ask them!

You might be able to do that in character – for example, the Cassalanters ask them why it’s so important for them to know the identity of their informant. But, as the GM, you can also just ask the players directly what their goal is.

Go to Part 1

In my Dragon Heist campaign, the PCs ended up adopting the orphans. (Something which I have rather good reason to suspect is far from uncommon.) They also decided that they would, of course, have to make arrangements for their proper education, and so they began arranging apprenticeships and tutors for them.

JENKS wanted to become a cook. (He’d already been hanging out with the cooks the PCs had hired for Trollskull Manor and had been helping out in the kitchen.) His apprenticeship in my campaign was rather bespoke, as the PCs had acquired Frewn’s Brews (after driving Emmet Frewn out of town), converted it into a bakery, and made arrangements with the Baker’s Guild to sponsor an apprentice cook who was ready to become her own master. Thus was born Amara’s Bakery, and it was quite natural for Jenks to be apprenticed there.

NAT wanted to learn magic. Eltorchul Academy was an arcane academy founded by the Eltorchul family. (Detailed in the 3rd Edition City of Splendors sourcebook.) The current headmaster is Ambrulavage and Nat was placed under the immediate attention of Miss Ferolie.

SQUIDDLY, inspired by the party’s ranger, wanted to become an archer. He was apprenticed to the Fellowship of Bowyers and Fletchers. The guildmaster is Javan Riautar and Squiddly was apprenticed to Master Kennadr.

TUTORS

In addition to their apprenticeships, the PCs also arranged for additional tutors. I had four tutors respond to their advertisement, and the PCs ended up hiring several of them.

NALOLIR is a podrikey — a dwarven mining construct with the brain and spinal column of a kobold inside it. Nalolir escaped from Undermountain a hundred years go and now focuses on teaching history. He speaks with a somewhat robotic voice, but moves with a gentleness and precision somewhat belied by the sheer mass of metal being propelled.

FIREDROP is a pixie philosopher. She teaches the three philosophers — natural (the properties of the physical universe), moral (the study of sentient thought and ideology), and metaphysical (lore of the arcane and extraplanar). Physically, she is effervescent, always in flight and flitting here and there. Her speech is erudite, while also reflecting the endless, bubbling font of curiosity which is constantly driving her.

STARAI is a kenku scholar. His teaching method is extremely Socratic, almost ceaselessly echoing speech as a reflected question.

ETHLANDO is an elven scholar who was once a magi. Tragically, he suffered a curse which stripped his magic from him. (He does not hide his history as an arcanist or the curse which afflicts him, but he does not speak of why or how he came to be cursed.) His owl familiar, Bulbuena, remains loyal and is rarely far from his side.

I’m not sure how much general use these tutors might see, but I had mentioned them in a live chat and a number of patrons reached out to ask if I would share my notes on them. As you can see, they were not given an abundance of detail: The PCs’ arrangements for their adopted kids’ education were happening towards the end of the campaign, and even the ones they ended up hiring did not have much time for development.

You might consider calling upon them for any occasion where you might have need of a scholar.

SPOILERS FOR DRAGON HEIST

A.M. asks:

One of my players is going to be leaving my Dragon Heist remix campaign soon. It’s currently five days before Trollskull Manor’s grand opening and two days before the fireball. We have two more sessions with her, and I have another player lined up to replace her when she leaves, but I’m not sure if it’d be better to pad things out a bit so the new player is part of the group when the fireball goes off; or breeze through and have the fireball with the old player still there.

There are three things I would consider here:

1. Is there any way that I can give the departing player a satisfying send-off?
2. How am I going to hook the new player in?
3. Is there any reason the new player can’t join before the old player leaves? (Which immediately alleviates any sequencing woes that might interfere with the best answers for #1 and #2.)

For the send-off, I’m looking for some kind of conclusion. Some dramatic note that allows this specific player to feel like their experience in the campaign is “complete.” This is, of course, good for the player leaving, but I think it’s also important for the other players, because it provides a sense of closure.

Generally speaking, this is going to boil down to either a major milestone in the campaign or it’s going to be about resolving a personal goal. In either case, though, you want to focus on what you know about the specific player: What stuff do they seem to care most about in the campaign?

MILESTONES

In terms of a milestone, for example, you’re in a somewhat awkward point of the Dragon Heist campaign where one set of objectives has been completed, but the next phase of the campaign hasn’t really kicked off.

If there’s not a natural milestone sitting right there, however, then sometimes you can fast-track a milestone. For example, if you think the nimblewright investigation could get wrapped up in a couple sessions (including the Gralhund raid), then you might fast-track the fireball and have it go off immediately. Discovering the culprits (Gralhunds) and recovering the Stone (albeit not its Eyes) might be a nice, satisfying milestone.

Alternatively, maybe this player seems to be really invested in Trollskull Manor. If so, focusing on the grand opening as their big conclusion might be the milestone you need. This might actually mean slowing down the milestone (so it arrives at the right time), possibly by adding an additional complication in the form of a mini-scenario to put extra weight on it. In the case of Dragon Heist, the campaign conveniently provides the machinations of Frewn, a business competitor, to disrupt the opening of Trollskull Manor: Maybe you’ve already resolved that in your campaign, but if not you can compress that down into the next couple sessions and have Frewn (and his wererats) go in HARD on screwing up the opening. Thwarting Frewn and celebrating a big, glorious opening day might be a great final session for this player.

Random Tip: In my Dragon Heist run, the players actually put together a menu for Trollskull Manor by having each PC name one food. Then one of the players actually made that menu for dinner one night. You could do something similar, creating a real world feast and celebration to mirror the one in your game.)

PERSONAL GOALS

In terms of personal goals, of course, this depends entirely on the specific PC in question. But it largely boils down to identifying the most important personal goal and wrapping it up.

• Are they seeking revenge on their father’s killer? Oh, look! There’s the six-fingered man now!
• Are they trying to raise money to raise their dead wife from the dead? Insert a mini-scenario that gives them access to a magic item that lets them do that. (If you want to run hard, simultaneously frame things up so that they’re faced with a dilemma: Do they raise their dead wife? Or the orphan killed in the fireball?)
• They wanted to become a teacher at the House of Wonder? Renaer arranges for them to get a position.

You may also be able to combine personal goals and milestones. For example, Renaer surprises them with the position at the House of Wonder during the grand-opening of Trollskull. Or it turns out Lord Gralhund was their father’s killer.

If you’re scratching your head over this or uncertain about what you should do, you can always unleash your GMing superpower by turning to the player and asking, “Hey. Is there anything you really want to get done before leaving the campaign?”

HOOKING THE NEW PLAYER

When it comes to hooking the new player, I discuss this in more detail here.

In most cases, even if you screw this up completely, the metagame will paper over the gaping cracks: Everybody knows this is Peter’s new character, so they will just kind of “naturally” accept him as part of the group. But it is, in fact, this kind of “go with the flow” tendency which, for me, makes it even more important to not have it be that simple; to have the new addition to the group make sense in character.

In terms of the existing player’s send-off, this is mostly significant if sequencing is a problem – i.e., the original player needs to leave before the new player can join, but it would be better or easier to bring the new player in before the milestone that would provide a satisfactory conclusion to the original player.

In these cases, I would almost always tip things in favor of the original player. It’s much more important, in my opinion, to make sure they get a proper send-off; they’ll be plenty of time for the new player to have rewarding experiences in your game.

If possible, though, I’d try to overlap the players. It can, in my experience, make the transition feel much more natural. The only reasons to avoid that would be either interpersonal issues (maybe the original player would be angry playing with the new player for some reason) or if the time dedicated to bringing in the new PC would make it difficult to drive the campaign towards the original player’s big send-off.

V. writes:

I’m heading into Chapter 2 of Dragon Heist next session. We left off right after Volo “paid” them with a deed for Trollskull Manor, so they want to start with inspecting the tavern in the morning. I’m going to have them re-encounter the urchins there, but then what? I’m not really sure how to keep the session moving after that.

Chapter 2 of Dragon Heist presents a little sandbox-like interlude between the introductory events of Chapter 1 and (in the Remix) the Grand Game literally blowing up on the PCs’ doorstep in the form of the fireball. It includes:

• Fixing up Trollskull Manor so that it can be re-opened (or sold or whatever else the PCs want to do with it).
• Other businesses and NPCs in Trollskull Alley for the PCs to meet and build relationships with.
• A half dozen factions who will be interested in recruiting the PCs, along with short faction missions that the PCs will be asked to do if they join up.
• A hostile businessmen (Emmek Frewn) who will hire a gang of wererats to harass the PCs.

To this toolkit, you can add any loose threads from Chapter 1 that the PCs are interested in pursuing: Relationships with Volo, Renear, Floon, etc. Investigations into the Zhentarim or Xanatharians. And so forth.

That’s a whole bunch of stuff! But how do you actually bring it to the table?

(As a quick aside: One important thing to keep in mind is that you’re not supposed to wrap up everything in Chapter 2 before Chapter 3 begins. The Remix, in particular, decompresses the Grand Game so that you have space to continue incorporating the faction and Trollskull business into the campaign. Doing so will add depth as the PCs’ actions weave together the Grand Game, the factions, and Trollskull into a dynamic interlock. But I digress.)

What you want do at the top of Chapter 2 is basically a massive dump of options — stuff that needs to get done around the tavern, scenario hooks, etc. You want the players to immediately have to start making choices about what they’re going to spend their time and focus on. This is what will keep things interesting.

To achieve this:

1. Factions will start paying house calls to say, “Hi. Heard you’re awesome. We have a job we’d like you to do.” Renaer is a VIP and saving him in Chapter 1 created a lot of buzz for the PCs.
2. Immediately start having guilds show up to discuss repairs that need to be made and services they can provide. (This is why the Remix breaks down the costs associated with repairs and assigns them to specific guilds. The guild reps humanize the expenses and the individual breakdown also gives the players a chance to think creatively about how they might work around each guild’s remit to save cash… while probably earning the guild’s enmity for scab labor.)
3. Get Frewn, the urchins, and one or two other people from Trollskull Alley involved. Frewn, in particular, will start a whole chain of events, but the ongoing relationships with the other NPCs will develop similarly in an organic fashion. (I recommend giving space to the other alley residents to give the PCs a chance to seek them out and explore the alley for themselves.)

Make sure that the guild costs are significantly (but not impossibly) higher than the group’s cash-on-hand. This will motivate them to figure out a paycheck (i.e., they can’t just focus on remodeling the tavern, they’re going to have to go do interesting things to pay for it).

Put them under a time crunch. They should NOT be able to do everything, at least not without splitting up. Have stuff from two different faction missions happen at the same time; or at the same time as the guild reps show up for some “hard negotiations.” They’re going to have to make choices.

Similarly, don’t wait for one thing to wrap up before triggering the next. Interrupt scenes with other scenes and hooks. For example, they’re negotiating with a guild rep when Frewn shows up or one of the urchins runs in to report that Nat has fallen into a sinkhole. Or both.

MAKE YOUR MENU

If this feels like a lot to juggle… it is!

Across all of these different elements of the campaign, you might have forty or fifty different things you’re trying to keep track of. It’s too much.

The solution?

Make lists.

Specifically, make a sequential list for each category:

• Guilds
• Factions
• Trollskull Drama
• Follow-Ups

Under “Guilds” list all the guild visits in the order you think they should happen (or just randomly if order doesn’t seem significant). Do the same for your faction recruitment/mission assignments, Trollskull-related NPCs, etc.

As you’re running, you can now just glance at your lists and trigger something happening by just grabbing the top item off any list. (This isn’t a binding contract, of course. You can still bounce around if it makes sense in the moment.)

This significantly simplifies what you’re trying to keep track of in your head at any moment: Instead of forty or fifty different items, you only have to think in terms of “guild stuff, faction stuff, and alley stuff.”

I think of it like ordering off a menu: If you dump everything into one big category, ordering is a nightmare. So you organize stuff into appetizers, main course, dessert, and so forth.

Then, during play, you’re like, “Hmm… Getting peckish. Let me take a peek at the menu.”

And because you’ve pre-organized stuff, you largely just need to jump back and forth from one menu to the next.

FOLLOW-UPS

“Follow-Ups,” it should be noted, is a list you can use to follow-up on previous scenes: They piss off a glazier guild rep, so you think, “That guy’s gonna bring some muscle to break their new windows.” Jot that down in your Follow-Ups list.

You could, of course, just add this to the end of the Guilds list, but then you’d have to cycle through establishing everything else on the Guilds list before the PCs would start experiencing the consequences of their choices. Alternatively, you could put it on the top of the Guilds list, but then you’d have to cycle through all your follow-ups before you could introduce new stuff. It’s better to keep a mix of new stuff and old stuff cycling through.

Note that stuff from Chapter 1 – like Renaer or Floon or Volo dropping by for a visit – could also go on the Follow-Ups list. This is a good way to transition stuff from one phase of a campaign to the next and is easy to keep track of on your campaign status document.

Go to Ask the Alexandrian #6

I have done remixes for both Waterdeep: Dragon Heist and Descent Into Avernus. It’s perhaps not unsurprising that I have been frequently asked how I would connect the two campaigns.

It’s not something that I, personally, had given a lot of thought to. My own run of the Dragon Heist campaign ended with the PCs poised to pursue very different goals: Some had become ensconced as leaders of the Harpers in Waterdeep. Others were heading to the Sea of Fallen Stars to pursue threads from their characters’ backstories. (Although we’re taking a break from those characters, I’m planning to return and run separate campaigns for both of those threads.)

So I guess that would be my first word of caution: It’s quite likely that connecting the two campaigns will actually be a really bad idea. By the time you get to the end of Dragon Heist, your campaign will have built up a lot of momentum, and all of that momentum is likely to be tied to Waterdeep. (The whole function of Trollskull Manor is, in fact, to give the PCs permanent ties to the city.) It probably makes more sense to follow that momentum (continuing to explore the factions and intrigues of Waterdeep) than it does to uproot the whole campaign and head south.

The other thing to note here is that the whole function of the Dragon Heist Remix is to turn the campaign into an active playground. I know where my Remix campaign ended up, but I honestly have no idea where yours did: Who are the PCs allied with? Which enemies survived? Where’s Neverember’s gold? What other resources have the PCs accrued? What enigmas are the PCs most interested in pursuing? Do they have the Stone of Golorr? If not, who does? Did they end up adopting kids or falling in love? The possibilities are almost limitless.

With those provisos in mind, here are some general thoughts on how you might connect the campaigns.

START AT THE BEGINNING

If possible, the first thing I would do is to plant the seeds of the transition from the very beginning. As the players are creating their characters for Dragon Heist, encourage some or all of them to make characters who have a connection to Elturel. This is more or less what I discuss in Remixing Avernus – Part 2: Character Creation, it’s probably just a little more difficult to explain why you’re encouraging the players to do this if the campaign is going to be taking place in Waterdeep.

First, this can easily include having Lulu as a PC in Dragon Heist. This actually fits in well with her revised backstory, in which she returns to Toril via a portal that takes her to Neverwinter before journeying south to Elturel. It might be interesting to explore that connection to Neverwinter — did she meet Neverember? Or perhaps she met Dalakhar? Alternatively, you might just move the portal so that it leads to Waterdeep (and she has likely just come through it as the campaign is beginning).

Second, you’re still going to want a Hellrider for Descent Into Avernus. Could they have been sent to Waterdeep to investigate links to Asmodean cultists who were recently captured in Elturel? Perhaps the cultists were kidnapping people in Elturel, and their interest in looking for similar disappearances in Waterdeep leads them to Volo (looking for people to investigate his missing friend) at the beginning of Dragon Heist? (This link will likely bias your Dragon Heist run towards the Cassalanters. The twist where the friendly nobles looking for help saving their Asmodeus-cursed children turn out to actually BE the Asmodean cult leaders will be great. More on this connection below.)

Third, for any Elturel-connected character the players do create, try to find ways for them to have unfinished business back in Elturel (or perhaps Baldur’s Gate). It’s quite likely that this business is what brought them to Waterdeep in the first place, but its conclusion is back home.

For example, in my Dragon Heist run one of the PCs needed to raise a large sum of money as a ransom for his mother’s freedom. (The nice thing about Dragon Heist is that literally any goal that requires large sums of money can be trivially tied to the central conceit of the campaign.) That link is part of what led half the group to the Sea of Fallen Stars (where that PC’s mother was being held). If that link had instead pointed back towards Elturel, it would obviously help a transition to Descent Into Avernus.

Check out Running the Campaign – Dragon Heist: Creating the Characters for an in-depth discussion of how to handle this type of character creation.

ASMODEAN CONNECTIONS

If I’m looking for an actual connection between the campaigns — the thing that will drive PCs from Waterdeep to Elturel — then what immediately leaps out are the Asmodeus cultists in Dragon Heist.

If you want to make the transition fairly organic, then you’ll want to seed clues into the Cassalanter faction of Dragon Heist that point the PCs towards either Elturel or Baldur’s Gate. (In the latter case, we’d most likely assume that the Cassalanters have a direct connection to the Vanthampurs. In the former, they would have connections to various Asmodeans heading to Elturel for the “Exodus.” Or you could do both.)

If the players are particularly interested in Cassalanters, finding an opportune time for the Cassalanters to flee Waterdeep and head for Elturel or Baldur’s Gate would also be a big pull. Alternatively, if the PCs are concerned about the kids, the Cassalanters might send them to Vanthampur for “sanctuary” as the noose closes around their own necks (forcing the PCs to chase them down).

For a slightly more focused experience, consider tweaking Dragon Heist to make the Cassalanters Zarielites instead of Asmodean cultists. Either way, you can seed a bunch of Asmodeus/Zariel lore into Dragon Heist (like the Averniad and the Trial of Asmodeus).

A slight risk with the “organic” approach is that the PCs might go haring off to Elturel before the Grand Game of Dragon Heist has reached its conclusion. If the PCs are in possession of the Stone of Golorr or any of its Eyes when they do this, the Grand Game will follow them. (The other factions need that stuff!) We might imagine a scenario where the PCs and a bunch of Dragon Heist-related faction members get sent to Avernus and the Grand Game continues while everyone simultaneously tries to escape Hell… but it’s probably not ideal.

Although the risk of this is, in my opinion, rather low, if you want to avoid any chance of this happening you can take a slightly less organic approach by waiting for Dragon Heist to reach its conclusion, selecting some faction that the PCs have become allied with, and having them dump a bunch of intelligence reports suggesting that those Asmodean cultists the PCs were recently tangled up with are active in Elturel. “Could you check that out for us?” (If the PCs were already heading that way to settle up personal business, all the better.)

On the other hand, if the Grand Game in Avernus sounds amazing to you, have the Cassalanters take their Eye to Elturel before the PCs can get it.

SPLIT THE PARTY

If some of the PCs are naturally interested in staying in Waterdeep to pursue their interests there while other PCs are interested in returning to Elturel to complete their unfinished business… Let them.

The players whose characters remained in Waterdeep simply need to create new PCs who can join the other characters as the other campaign begins. (If your plan is to lead with the Elturian refugee caravan, for example, the other PCs could be members of that caravan or join the other PCs in protecting it. This might also be an ideal time to introduce Lulu as a PC if you haven’t already.)

As I mentioned earlier, this is similar to what happened after my Dragon Heist run: Some of the PCs stayed in Waterdeep. Others went to the Sea of Fallen Stars. If all goes according to plan, I’ll be running both of those as separate campaigns.

THE STONE OF GOLORR IN AVERNUS

If the PCs still possess the Stone of Golorr after the events of Dragon Heist, its legend lore abilities alone offer many cool opportunities for the PCs as they delve into the deep lore of the Descent Into Avernus remix. You’ll want to give some thought to cool legend lore responses to topics the PCs are likely to ask about (like Zariel, Lulu, etc.). What stuff qualifies as “legendary” (so that the spell works) and what doesn’t?

Also decide if the spell’s description of “the more information you already have about the thing, the more precise and detailed the information you receive is” means you can benefit from casting legend lore multiple times (gaining more detailed information each time).

It might also be cool to think about how the backstory of Descent Into Avernus might be tweaked to incorporate the Stone of Golorr. Specifically, is there some big secret of the campaign that the Stone might have been used to erase from common knowledge? (For example, perhaps one of the original Hellriders decided to use the Stone to eradicate the knowledge that Zariel led the Charge of the Hellriders.) Seed some clues to that effect, so that the PCs can use the Stone to their advantage.

The Stone of Golorr might also be an alternative source for the Vision from Torm, pointing the PCs in the direction of the Sword of Zariel.

ADJUSTING FOR LEVEL

I haven’t discussed adjusting the level of challenge in Descent Into Avernus. Broadly speaking, these adjustments should be obvious. (Make the bad guys tougher and/or add more of them.)

In some ways, this will actually be to your advantage: There are wide reports that the beginning of Descent Into Avernus is too difficult for beginning characters. (And I’ve already discussed in the Remix starting the characters at a higher level.)

Speaking in very general terms, I would:

• Cap level advancement in Dragon Heist to 6^th. (It’s possible to get to 7^th in the Remix, just don’t include that final milestone advance.)
• If your group won’t get crabby, you can just hold advancement until they leave Elturel.
• Alternatively, give them a milestone level up to 7^th level when they leave Baldur’s Gate and again when they leave Elturel. (They’ll be a little higher level than they should be in Elturel and when starting out the Avernian hexcrawl, but close enough that you can probably get away without making any adjustments to those sections of the campaign.)

Alternatively, skip the Baldur’s Gate section of Descent Into Avernus entirely: Pull the PCs from Waterdeep to Elturel. Then, as they arrive, have the whole city sucked into Hell with them along for the ride and continue the campaign from there. To make this really work, seed the information and resources the PCs would have received in Baldur’s Gate into the Cassalanter sections of Dragon Heist.

For example, the infernal puzzlebox can be an artifact held by the Cassalanters. Maybe the PCs’ allies come to them and say, “Hey, we found this among the Cassalanters stuff. Sylvira Savikas is an expert on this stuff. She lives in Elturel. Can you take it to her and see if she can open it?” Or maybe they just take it to the Blackstaff and have her crack it open; then, armed with the evidence in side, they head to Elturel to expose the conspiracy… but they’re too late! The city is sucked into Hell just as they arrive!

WATERDEEP IN HELL

Why bother moving the campaign to Elturel at all? Why not just swap in Waterdeep and send the City of Splendors to Hell instead (with the PCs along for the ride)?

First, the City of Splendors is chock-a-block with high level NPCs (including many whom the PCs have been directly interacting with during Dragon Heist). There will be an obvious question of why these NPCs aren’t solving the problem themselves instead of leaving the PCs to do it.

Second, once you make all the fundamental changes to the lore of the campaign necessary to move it from Elturel to Waterdeep (no Companion, no Charge of the Hellriders as a central element, etc.), in practice you’re not really running Descent Into Avernus any more. You’re running a completely new campaign that you’re designing almost entirely from scratch.
