Arcane Pulse

Channeling the Weave, you begin to emanate harmful pulses of magic. Each creature of your choice in a 15-foot-radius sphere centered on yourself must make a Dexterity saving throw. On a failed save, a creature takes 1d12 force damage. On a successful save, a creature takes half damage. On subsequent turns, for the duration, you can use your bonus action to release another pulse.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d12 for each slot level above 1st.
