Draining Aura

Drawing from the souls of those who've past, you use your action to create a deathly aura going 60ft from you in all directions. When you make any attack or an ally makes a melee attack you deal additional damage based off your spell casting modifier. You additionally heal an amount equal to your spell casting modifier whenever a creature takes damage cause by your or your allies in your aura. The restoration and extra damage can only be triggered once per turn.
