Thirsting Vitreloy

your arms become sheathed in liquid metal. as the metal seeks out the blood of your enemy's, branches of silvery tendrils form to efficiently attack any creatures within range. each creature within range except for yourself must make a dexterity saving throw or be stabbed by the reaching branches. a creature who is stabbed takes 2d6 necrotic damage as you regain half that damage in health. all creatures including you have disadvantage on attack rolls while this spell is active. the area in a 10 foot radius around you is difficult terrain. this spell moves with you when you move and continues to effect you while it is active.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d6 for each slot level above 2nd.
