Entity: Slabsoul Minotaur

Source Howl of the Wild pg. 42 ^2.1

Your deep connection with stone and walls allows you to conjure massive slabs of granite that collapse on your foes. You gain the Raise Slabs activity.

Raise Slabs (earth, divine) Frequency once per day; Effect Thick slabs of stone rise around you before tilting over. You deal 1d6 bludgeoning damage to all adjacent creatures (basic Reflex against your class DC or spell DC, whichever is higher). On a critical failure, the creature is also knocked prone. At 3rd level, and every 2 levels thereafter, this damage increases by 1d6.
