Draining Smite

Deal additional necrotic damage to the target of your next melee weapon attack.

The extra damage is 2d6 plus 1d6 for each spell level higher than 1st. The damage dice increase to d8's against a target of good alignment.

If your blade is sated, grant 1/4 the necrotic damage dealt in this hit as temporary hit points, rounded down, that last for 1 hour.

Missing with a roll of (your proficiency bonus) or less deals half your normal necrotic damage to yourself, and if sated you loose your sated state until you next deal necrotic damage
