Touching a suffering creature with your palm, you relieve it from its pain. You take 1d8 Necrotic damage, which can’t be reduced in any way. Your Hit Point maximum decreases by an amount equal to the Necrotic damage taken, and the spell's target regains Hit Points equal to that amount.

Cantrip Upgrade. The damage can be increased by 1d8 when you reach levels 5 (2d8), 11 (3d8), and 17 (4d8).
