Energy Bending

With your connection to the life forces, you gain the ability to transfer 4d10 to yourself from a creature you touch, given they fail a constitution save. Upon, a successful cons save they receive half damage and do not transfer the hp to you or another creature.

 At level 16, you can chose to transfer hp into another creature. The creature receiving the hp will only gain half of the hp taken from the original creature, the rest will be taken as damage caused by the spell. Doesn't work if one or all creatures are undead.
