Acadia's Necrotic Smite

When you make a weapon attack, you can imbue the strike with necrotic power, dealing 3d8 necrotic damage in addition to the attack's damage.  If you kill a target with this spell, it immediately raises as a zombie that serves you for 1 hour before dying again, it shares initiative, and must be ordered to attack as a bonus action, otherwise it will only dodge.
