Tower of Doom/Traps

Traps
Other items yet to be identified may bypass certain traps as well.

The Magenta Key will bypass all traps, and the Brown Rosary appears to confer permanent immunity from traps. The Bright Green Scroll (whether small or large) will remove all traps in the current level.

The game's collision detection will sometimes register your hero as touching a trap even if you're clearly in the next square over. This can happen even if you're separated from the trap by a wall.

Once in a while, the game will "ding" you for a trap right as you enter a room, even if you're nowhere near the trap.
