Void

For a brief moment pure darkness pulses from you, making all creatures in a 30 foot radius sphere from you know know darkness so well they forget light. All creatures except you in range must make a Wisdom saving throw, taking 5d10 necrotic damage and falling unconscious for 1d10 rounds on a failed save, or taking half as much damage and being blinded for 1d6 rounds on a successful one. A creature that fails its save can make a Constitution saving throw every time it is damaged while unconscious to end the effect early.
