Desiccating Inhalation

Frequency once per hour

You draw in the moisture from nearby creatures, draining them dry to heal your wounds. Creatures in a 30-foot cone take scaling d8 void damage, with a reflex save against your class DC. A creature that critically fails this saving throw is also Drained 1. As long as at least one creature was damaged by your Desiccating Inhalation, you regain HP equal to your level.

At 14th level and every 2 levels thereafter, the damage increases by 1d8.
