Proximity Alert Mines
Feat 10
Source Tech Core pg. 45
Prerequisites mine exocortex
You’ve rigged your mines so that whenever you Deploy Mine, you can make the deployed mine a proximity alert mine. If you do, the mine automatically Detonates when a creature enters or leaves a square within the burst area of the mine. This doesn’t take an action, and you can’t choose to delay the mine’s detonation when it would trigger.
