If a trap is active, it is hidden from view, unless placed by your character. However, you can detect these hidden traps by [[Search]]ing and thus can avoid them. All traps can be used to efectively dismember your enemies, if you fel so.
Note that planting any trap inside a city ([[Attnam]] or [[New Attnam]]) will likely result in an injured resident and subsequently all instantly make the population trying to slaughter youentire city hostile.
