Aura Link

You share a link between yourself and another creature within 60 feet of yourself. In a moment of connection, you and that creature forms a bond for a split second.

When you cast a spell that has a range of self, you may instead cast it unto someone within 60 feet of yourself. That creature is under the effect of the spell as if that creature had casted it, and when you do cast it unto someone else, both you and that creature gains temporary hitpoints equal to your proficiency bonus, You may use this feature a number of times equal to your proficiency bonus. 

When you take this feat, choose a 1st level spell from any spell list with the range of self. You may cast that spell once per long rest without using a spell slot.
