Bloodletting Smite

The next time you hit with a melee weapon attack during this spell’s duration, the target takes an extra 3d6 necrotic damage and begins to bleed uncontrollably.

For the duration, the creature takes 1d6 necrotic damage at the start of each of its turns. If it drops to 0 HP while bleeding, you may immediately mark another creature within 30 feet with your Blood Tithe without using your reaction.
