Needle Fall

Trigger A creature touches any consonite needle

Effect The needle snaps, and the vibrations resonate with some of the surrounding needles. The falling minerals deal 2d8+7 damage to creatures within a 5-foot burst surrounding the triggering individual (DC 22 basic Reflex save). The needle fall doesn't involve every consonite growth within these squares, so can be triggered again from the same location.
