Earth pillar

Cause a pillar of stone to erupt from the ground, creating a hole underneath where it is summoned. The pillar deals 1d8 bludgeoning damage and launches all creatures below the pillar 40ft into the air. The pillar is a 15ft radius, 20ft tall stone pillar. After the pillar erupts from the ground, it crumbles and disappears, causing the hole to fill back in halfway, leaving behind a 10ft deep hole.
