Traps are basically tiles in the floor with special effects that are activated
whenever Ashley steps on them. Most of the time, these effects are negative, resulting
in direct or indirect damage to Ashley, although there are traps with beneficial
effects. A trap is completely invisible, indistinguishable from any other space in the
room, until one of two things happens: Ashley steps on it or reveals it via the Eureka spell or
Eye of Argon item. At that point, the trap will start to glow; however, if you leave
the room and come back in, it will be hidden once again. If it is disarmed via a Trap Clear
trap, it will rearm when Ashley leaves the room.
Traps cannot kill Ashley directly, and none of the traps that does direct damage will
be able to deplete his HP entirely. However, they can easily kill him indirectly, by causing
negative, potentially deadly status changes, or by weakening him for the benefit of any enemies
in the room. If Ashley is in Battle Mode when he steps on a trap, his armour will protect him against
that trap, and he will take less damage than he would have outside of Battle Mode. Similarly, any Gems
for defending against negative status changes that might be equipped on Ashley's armour will be in
effect if Ashley is in Battle Mode when he trips the trap.
Traps will affect enemies if they trigger them, so you can try to use this to your advantage.
It will rarely be a viable scenario, though. Lastly, falling off a cliff or into a hole or waterway will automatically
do 20 HP of damage to Ashley, regardless of his armour. Unlike stepping on a trap, falling off cliffs can
kill Ashley directly.
