Call the Blood (Archlich)

With a word and a gesture you cause streams of blood to burst from the target's mouth, nose, and eyes. The target takes 8d4 necrotic damage or half as much on a successful save, and you regain hit points equal to half of the damage dealt. Alternatively, you can choose to forgo regaining hit points and instead gain the effects of the Haste spell until the end of your next turn, excluding the wave of lethargy
