Traps are hidden throughout the entire game(one may wonder who did :D), and are usually triggered by the unwary stepping into the same tile as the trap icon. There is a small chance of detecting nearby traps, enhanced by the percentage on a worn ring of protection which acts as a bonus and can be improved up to 100 with scrolls of blessing (-1 to +2 depending on cursed/blessed status) or enchantment (+5 to +15).
There is a chance to evade triggering most traps, and the levitation ability dramatically increases this rate. You may deliberately trigger a trap you evaded by using the Down Stairs key while standing on it.
Monsters may set off traps. Levitating ones won't drown in quicksand(unless probably captured by a net). Most monsters shrug off the effects and continue attacking you unobstructed unless stunned, trapped, or killed.
