Transfer pain

Upon casting this spell you may move up to 6d4 points of damage from 1 creature to another within range (effectively healing the first creature). If the recipient of the damage is unwilling to recieve it they may make a constitution saving throw against your spell save dc. On a succes the damage is dealt to the caster. The amount of damage transfered cannot cause the creature getting healed to exceed it's hit point maximum and is dealt as necrotic damage to the recipient.

The amount of damage transfered increases by 1d4 for every spell level over 3rd.
