==Description==
You reach out and touch a creature, letting the corruptive Essence of Chagrin flow through your fingertips. The target must make an Intelligence saving throw. On a failed save, it takes 1d8 Essence damage, and you regain hit points equal to half the amount of Essence damage dealt.
This spell's damage increases by 1d8 when you reach 5th level (2d8), 11th level (3d8), and 17th level (4d8).
==Notes==
*All Essence damage dealt is doubled, but half of the damage is also dealt to the caster.
