Curse Transference

You establish a temporary blood link that allows you to transfer curses between creatures. Choose two creatures you can see within range (which can include yourself). The unwilling target must succeed on a Constitution saving throw or be affected by the spell.

Upon casting, you can transfer any or all Blood Curses, magical diseases, or curse effects (as determined by the DM) from one target to the other. When transferring a Blood Curse from one creature to another, the receiving creature takes 4d10 necrotic damage and must make a Constitution saving throw. On a failed save, the curse is transferred at full potency. On a successful save, the curse is still transferred but its duration is halved.

As an alternative use, you can attempt to lift a curse from a single creature and absorb it into yourself, transmuting its energy. Choose one Blood Curse or curse effect affecting a creature you touch. Make an ability check using your spellcasting ability. The DC equals 10 + the spell level of the curse (or 15 for non-spell curses). On a success, the curse is removed from the target and you gain temporary hit points equal to your spellcasting ability modifier + twice the spell level of the curse (or 10 for non spell curses).

Blood Sacrifice. When casting this spell, you take 5d4 damage as your blood creates the curse-transferring link.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, you can target one additional creature for each slot level above 5th, creating a chain of curse transfers, or you gain a +2 bonus to your ability check to absorb a curse for each slot level above 5th.
