Beacon of Undeath

You begin to radiate an aura of necromantic energy.Any number of undead of your choice within range of you gain advantage on attack rolls and saving throws, and ignore half cover. In addition they regain a number of hit points equal to 1d6 + your intelligence modifier at the start of each of their turns as the unholy energies slowly stitch your undead servants back together, Allied living creatures in range also regain hitpoints, but without the bonus added.

At higher levels. When cast with a spell slot of 5th or higher the healing increases by 1d6, and again for every two spell slots higher beyond 5th. (7th = 3d6, 9th = 4d6).
