Dead-end platform - not quite a wall trap, but it’s very easy to hit it if you’re not careful:

The room with narrow strips going to the corners where chests sometimes spawn can have traps along these narrow strips, making it impossible to collect the chest without hitting the trap:
There are three similar rooms that have fences coming out of three walls
- One of these rooms is at the top of some stairs, and has a trap at the point of the fence on the south (right) wall:
- One has no stairs going into it, and has traps along the south-east (far left) wall and at the point of the fence on the south (far) wall:
- One is at the bottom of some stairs, and has no known wall traps
