Transfer Curse

At your touch, all curses affecting one object are transferred into the designated object. If the item is currently attuned to a character, the newly cursed object is now attuned to this character instead. 

Upon the transference of the curse, the caster must roll a Wisdom Saving throw (DC 15). On a success, nothing happens. On a failure, the caster takes 1d10 nectrotic damage per level of the curse that was bestowed. This level can be identified using an Identify Object spell or possibly through clever use of the Detect Magic spell.
