	When exploring new tiles that haven't been seen before, there is a depth-based chance that the player will trigger a '''malevolent force'''~~. There are three types of~~ effects ~~that can be triggered~~:		When exploring new tiles that haven't been seen before, there is a depth-based chance that the player will trigger one of three '''malevolent force''' effects:
	* '''Alarm trap effect''': the same as if the player stepped on an alarm trap; causes an extremely loud noise and [[Sentinel's Mark\|marks]] the player. This effect cannot be triggered on D:1-3.		*'''Alarm trap effect''': the same as if the player stepped on an alarm trap; causes an extremely loud noise and [[Sentinel's Mark\|marks]] the player. This effect cannot be triggered on D:1-3.
	* '''Shaft effect''': the same as if the player voluntarily took a physical shaft; causes the player to fall 1-3 floors deeper in the branch with no immediate way to return to the higher floor. See '''[[Shaft#Exploration Shafts\|Exploration Shafts]]''' for when they can and can not trigger.		*'''Shaft effect''': the same as if the player voluntarily took a physical shaft; causes the player to fall 1-3 floors deeper in the branch with no immediate way to return to the higher floor. See '''[[Shaft#Exploration Shafts\|Exploration Shafts]]''' for when they can and can not trigger.
	* '''Teleport effect''': causes you to be teleported to a random location on the current floor that is next to monsters, like the [[teleportitis]] mutation. This effect will fail to trigger if the game cannot find any such locations on the current floor.		*'''Teleport effect''': causes you to be teleported to a random location on the current floor that is next to monsters, like the [[teleportitis]] mutation.

	Note that new tiles revealed immediately after a shaft or teleport effect won't trigger another trap effect, giving the player a bit of a break post-trap.
