Alarm trap
| While this trap does no damage by itself, its loud sound may bring someone to do damage to you. Of course, you have the option to do damage to those someones yourself. |
An alarm trap is a trap which produces a loud noise (intensity 40, louder than Shatter) when stepped on by either you or a monster, alerting anything nearby. If you step on one, it also afflicts you with the Sentinel's Mark status effect (ignores magic resistance). Like all traps, alarm traps can be set off even by flying beings. After triggering once, they disappear.
Alarm traps cannot be disarmed, but can be silenced. Silence does not prevent the Sentinel's Mark, though.
If an alarm trap is triggered by a being in the distance, you see this message:
"You hear a distant blaring wail to the [direction]."
Strategy
If you're travelling through an early floor you've already cleared, find an alarm trap, and need a quick bite, stepping on it is not a bad way to summon any potentially edible opponents to you.
History
Prior to 0.12, alarm traps could activate multiple times before breaking, but they were not quite as loud and did not afflict you with the Sentinel's Mark.
