What? Why can't it unlock?

Damakos casts wall of stone to hold up the ceiling.

(something has come to my attention) all the way to bills investigation for traps. Bill cha' and demakos are still in the room with the card. Bill the case is trapped magically so you can't do it with theives tool's.

Vahl you are still in the hallway bit put of immediate danger. Are you doing anything?

Bill Notices the glimmer of magic and Grudgingly looks at Damakos. "There is some sort of magical trap on this pedestal. Think you can do anything about it?"

No I can't disarm it but I'll try to see what kind of trap it is.

15 arcana check or 22 investigation roll.

You can't tell there is even a trap

Bilberry calls to  Ta'Cha' . "There is some sort of magical trap on this device can you check it out?"

I yell through the blocked wall at our companions, 'You guys ok?"  I would like to do a perception check to see if I feel the vibrations from then moving ceiling on the other side of the door.

perception 22

Are you not seeing the posts or something? I retconed and when to before the explosion because bill would have seen the trap. Read this page again. Page 18.

Damakos is going to make an arcana check to see if the door is a magical object. 16

You can't tell. Its just a door to you.

What is in this room again?

A alter with a statue behind a case with a card that looks like the from reaper in it. All next to the wall to the left of the door. The room is a rectangle. The wall farthest from the door to to the left about 30ft and the wall opposite the door is about 15ft away fro. The door.

Ok

Bilberry will attempt to disarm the magical trap.

Arcana: 10

Slight of Hand: 24

Bill you try to disarm the trap but a little into it you think that if you continue you could set it off. (It's arcana. You can try it again but it will go off if you can't)

And the ceiling isn't falling outside yet correct?

The trap wasn't sprung so no)
