Disable Acrobatics DC 20 (trained) — or Stealth (trained) to shimmy past the bones without disturbing them, or deal any amount of damage to trigger the collapse from a distance

Trigger A creature moves through the treacherous squares near the bone pile or damages the bones piled in one of the squares

Effect The bone pile collapses in a torrent of skeletal remains, spreading 5 feet in every direction from the bone pile's current area. This deals 6d4+9 bludgeoning damage to each creature within 5 feet of the bone pile (DC 20 basic Reflex save). The area becomes difficult terrain.
