Area of Force

Pillars of crystal rise out of the ground in a 30ft circle of the caster. The pillars do not move from where they are originally summoned. The pillars can be activated each turn as a bonus action for (2D8) force damage to every enemy creature within the pillars. The pillars last for 1 minute or until dispelled.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1D8.
