In waiting for him to add to his lv6 spells with the memory addition. Imagining a spell shaped into a creature of magical energy. Or literal magical constructs. Not necessarily like the Susanoo from Naruto mind you made of chakra but living armors, literal creatures and animals and the like. I suppose higher than that would be actual concepts. Like a magic linked to myth and legend. So creating a jar or sword, fan, or whatever that is a replica of something of legend. While behave with similar properties as its mythos. Or self created ones acting as man made artifacts but purely of magic that can be conjured up on a whim without having to be crafted. Like a pot that can absorb a person in certain circumstances into itself and slowly break them down into liquid to be used to drink and boost oneself. Or simply as a prison. Or a space with mana construct beasts to fight and keep busy inside. Many things.
