Deathly Smite

The next time you hit a creature with a weapon attack before this spell ends, the weapon gleams with a dark aura as you strike. The attack deals an extra 2d6 Necrotic damage to the target, if the target dies they are resurrected as a zombie in the next 1d4 minutes. 

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