Youth

You attempt to strike a creature within their very soul and link each others' spirits. The target must make a Constitution saving throw. On a failed save, it takes 5d12 necrotic damage or half as much on a successful one. If the spell kills the target, you get younger and absorb its soul energy. The maximum amount you can get younger is equal to the damage dealt represented as years. By doing so, the soul is consumed and destroyed.

If the soul is not in the same alignment as you, you must make a DC 15 Charisma saving throw or your alignment changes to the creature's alignment and you retain some of its memories, at the discretion of the GM.
