So we've just had our second session of E4aE. Everything's pretty much going by the book. The party are all spread out a couple of hours after dinner. The bright wizard went to check out the library to find the librarian seemingly reading his book. I was thinking he was getting ready for the ritual and managed to look innocent as the wiz arrives, but that doesn't have to be the case. The librarian manages to blow the wiz off with an excuse about it being late and says he has to leave soon, and invites him back the next morning. The wiz thinks this is a bit dodgy (with all the rest of the strange that has been going on) and he hides outside the library to wait for the librarian to leave. He hears something like a door and waits a few more minutes before deicding there must be some secret way out of the library, so he goes back in and checks the place out.
It's getting late and the wiz only has 4 wounds, and it's a bit tense coz they know something very spooky is happening, and the earlier sighting of the painting has put the PCs all ill at ease. I ask the player to describe what he's doing, and he doesn't mention the floor, his desc is all about shelves and walls. I give him a Hard (3d) observation check to find the trap door. He rolls Boon Boon Boon Boon Success Success Success Chaos Star Chaos Star Chaos Star.
I'm trying to think what to say, but I can't think of anything good, so we just end the session (it was time anyway). So, any ideas? There's (presumably) a cellar full of cultists and a daemonic painting directly below him. I was thinking of having him just fall through the floor, but that's a bit mad, and will probably kill the wiz in any case. I'm also thinking about giving out some miscasts coz of the proximity to the Chaos artefact, but as he wasn't using any magic at the time, it doesn't sound very good. I could just read the dice conventionally and come up with a couple of boon effects, but I'd really prefer to use the 3 CSs in a creative way, and then mitigate whatever danger might occur with success and boon effects.
Any ideas?
