The Black Nail is a demonic tower that’s been driven into the ground. There’s a bunch of bizarre stuff on each floor, all of which leads down to a giant hand holding a large, stone chest at the bottom. The chest probably contains a demon, artifact, magic item or something pertinent to your campaign. Let me suggest you go one of two ways with this:
- There’s a demon/monster/enemy in the chest, or
- The hand holding the chest is the monster and it attacks once the players open it.
Or you could do both. I put some suggestions on what to do with the other rooms in the DM notes, so patrons may want to check those out.
Next, I’m going to make a variant of this map for patrons. It’s nothing too elaborate, so I should have it done in a couple days, but I think it might be useful to some of you. Anyway, I’m gonna get to work on that. Let me know what you think!
