Agron’s Bestowal of Vampirism

The touch of your shadow-wreathed hand bestows vampiric energies to a willing creature until the end of their next turn. The creature’s next melee attack does an additional 10d6 necrotic damage and heals the attacking creature for half of the total damage dealt.

At Higher Levels. When you cast this spell using a spell slot of 7th level or higher, the damage increases by 1d6 for each slot level above 6th.
