Consonite Clusters

HAZARD 7

Stealth +17 (trained)

Needle Fall

Trigger A creature touches any consonite cluster

Effect The needles snap, and the vibrations resonate with some of the surrounding clusters. The falling minerals deal 2d10+9 damage to creatures within a 5-foot burst surrounding the triggering individual (DC 22 Reflex save). The needle fall does not involve every consonite growth within these squares, so can be triggered again from the same location.
