Aura of Imbalance

Waves of positive and negative energy radiate from you in an aura with a 30-foot radius. Until the spell ends, the aura moves with you, centered on you. Whenever an ally regains hit points while within this aura, they gain an additional 2d4 hit points. Whenever an enemy within this aura suffers damage, they take an additional 2d4 necrotic damage.
