Trap Vaults
I wanted somewhere to put this stuff - I'm going to describe the things and post the code. If anyone has suggestions for them, I'd appreciate. After they're up for a bit if they seem ok I'll post em to mantis.
The first trap (that I haven't put on the mantis) is a Xom altar.
The Xom altar is a small room with a mini hallway leading into an altar to the god. There is a wand in the hallway
When you approach the altar one of two things will happen.
1) if there is a monster in the room with you, Xom will laugh at you and remove the item.
2) If there is not a monster in the room, Xom will guffaw and allow you to approach. When you do pick up the item, the corridor will extend (walls are added) and a monster will appear at the other end
There is an exception: if you apport the item or the item is otherwise not where it's expected to be when you pick it up, Xom laughs at your impertinence and nothing happens to you
The wand is either teleportation, digging, or a small chance of random effects. This isn't intended to kill you, though that's a happy side effect in Xom's opinion.
This is the code used:
And here is the map:

When you pick up the item, it only triggers the event if you don't already have the item identified. Not really sure if there's a different trigger I should be using, if there's a workaround or if this is an unintended bug or what.

# Xom Altar Trap
# In front of Xom's altar is a useful (preset) item. He warns you that you shouldn't pick it up.
# If you approach the altar followed by a monster, Xom dissapears when you hit the pressure plate,
# as does the item.
# If you approach the altar alone, Xom's altar dissapears and a he turns the empty spaces into a
# closed corridor. He then spawns a monster (+5 depth) at the other end of a corridor.
# The item you pick up is a wand geared towards escape / saving you options but with a small chance
# of random effects
