Curse Bearer

When under the effects of a cursed item you can trick the negative effects of the curse by attaching a sliver of your soul into another creature.

Unless the creature is willing. When you touch the target creature it must succeed a Charisma saving throw or be cursed by you.  

You lose 10 Max HP.  You cannot regain this HP in any way while the spell is active.

The target gains 10 max HP.  The target also takes any negative effects of the cursed item (decided by you and the DM) until the spell ends or the curse is removed.

If the target dies, moves to a different plane then you, or has the curse removed by the Remove Curse or Greater Restoration spell you do not regain your lost the maximum HP.

You can only end this spell by ending your attunement to the cursed item.
