Life Drain

Bearing a strong and dominating soul, you posses the ability to drain the life force from others. 

• By your Wisdom modifier (minimum 1) per short rest, when you hit a creature with a melee attack, you can drain life as the target loses hit points equal to your proficiency bonus, and you regain the same number of hit points.

If you reduce a creature to 0 hit points with this feature, gain temporary hit points equal to your proficiency bonus.
