Vital Exchange

You touch a willing creature and exchange a portion of their vitality with another creature within range. Choose two creatures within 30 feet of each other. The first creature looses hit points equal to 2d8 + your spellcasting ability modifier, and the second creature gains hit points equal to the amount lost. If the second creature's hit points are already at their maximum, the spell has no effect on that creature.

At Higher Levels: When you cast this spell using a spell slot of 4th level or higher, the amount of hit points exchanged increases by 1d8 for each slot level above 3rd.
