DISCUSSING
In the Shadow of the Spire – Session 33E: Maggots & Ratsbane

Someone threw themselves against the door Dominic and Tor were propping themselves against. It barely budged. They glanced at each and made a quick, unspoken decision. Dominic stepped away and Tor, timing things perfectly, yanked the door open at precisely the right moment.

A young elf woman – ebon-skinned like Shilukar – came stumbling through, thrown off-balance by the sudden disappearance of the door she had been planning to throw herself against.

Dominic and Tor were quick to take advantage – the former’s mace crushing her upper arm and Tor’s sword cutting deep into her thigh. She stumbled further down the hall, shouting over her shoulder. “Theral! There are six of them! Grealdan’s dead!”

Dominic looked through the open door and spotted Theral – the Brother of Venom that Tee had seen discovering Reggaloch’s body – beginning to cast a spell. He promptly slammed the door shut.

Back in Session 13B: The Tragedy at the Door, the PCs lost control of a doorway and nearly paid the ultimate price. In this session you can see them take control of a doorway and repeatedly use it to their advantage during the fight.

I often see doors getting ignored during fights. I think part of that is tied into some of the issues I discussed in Dungeon as a Theater of Operations: We have a tendency to get strongly locked into the idea that there’s a “fight keyed to Area 5” and, therefore, the fight takes place in Area 5 (and nowhere else). This, of course, frequently eliminates the door leading into Area 5 as being irrelevant.

I’m uncertain how much the proliferation of VTTs may be affecting this (since they often persistently feature the entire map of the dungeon), but “put the PCs in the room and then start the fight” is an attitude that you can even find infecting published adventures.

But just look at what a door can do for you! (Or to you.)

They’re natural chokepoints, allowing small groups (like PCs) to control their front line against much larger groups.

They can be used to control line of sight (and also effect), as seen here with Dominic using a readied action to slam the door shut and negate an enemy spellcaster’s entire action.

They can be used to separate groups, tactically isolating them and allowing them to be defeated in detail. (This is similar to attacking an enemy force when they’re halfway across the river.)

Conversely, if you move through a door and engage an enemy on the opposite side, then the doorway becomes your means of retreat. If you lose control of the doorway or are otherwise cut off from the doorway, then you’ll become trapped.

If someone is holding a door and using it against you, then you need to develop some method for breaching the door. (Or, alternatively, creating an alternative method of egress — using a window, teleporting, blasting a hole in the wall, turning ethereal, etc.)

In practice, of course, all of these myriad tactical considerations will be swirling around each other in the chaos of battle.

And we haven’t even started looking at doors with special features!

• How can a trapped door be used to your advantage during a fight? (Particularly if the trap resets whenever the door is shut.)
• What about doors that have magical effects attached to them? (Like magic portals!)
• You can get similar effects with non-magical portals, too! (For example, you might have a portcullis that’s rigged to come crashing down when someone pulls a lever.)

Some of these will create unique tactical opportunities. Others will simply complicate the ones we’ve already discussed!
