Does it return to the user after beeing used and is it permanently purified? Since vows can make an ability from weak to op it wouldn't be feasable to purify all of them. If it could be done the purification Process should take centuries exponentially incresing with the number of vows to bypass. Also the purified ability shouldn't be usable for the original user.

As a diffrent idea I would suggest that it simply turns every condition in time between uses making it so that he has to puriy it for every use. Destroying te cristal in which it's keapt should return the ability and a cristal containing an ability should be summoned all the time and be inside a limited range of the user. This would lead me to think that the ability originates from the cristal and the user can manipulate them. A diffrent idea would be to treat them like a Lich's filaktrum so it is stationate and containes the Nen abilities. the user has to hide the cristal and it's destruction forces him into Zetsu until the cristal reforms while the user loses all the abilities contained inside while they return to the original user. If they were in a purified state the original user could use it once without limitations.
