Eldritch Lifesaver

You’ve learned to cannibalize the power of your spells to reinvigorate your allies. As a bonus action, you can expend a spell slot of 1st level or higher to heal yourself or an ally within 30 feet. The number of hit points healed equals the level of the expended slot. In addition, the target gains temporary hit points equal to your spellcasting ability modifier. You must finish a long rest before you can use eldritch lifesaver again.
