I would like for you to think of this idea when he gains back his original State what if he gained a new class called celestial shade monarch I think it would be a more powerful version than the original Shadow monarch allowing him to control more of his magic output as well as being very physical as well also his original daggers I think it'd be cool if they were different than not the original ones what if it was more of twin short swords just a thought
how about as a item you make a sharp pointed halo that increases dark power and magic and intelligence by 100% and can be control telepathically like a spinning blade with its main powers to support magic beyond independently that he always wears . this could be world item that he won by completing a fallen angel like guest after discovering a chain quest that makes him have to avenge a fallen angel army that wanted freedom and work with other powers beside holy but was denied and their souls from their seals give him a quest to search for their fallen bodies and find their killers and monsters and set them free. the halo can be a prize to he completing the quest by himself as it is meant for a large group.
