[@Tawny Swan] Anything except dark magic and anything that falls under that is acceptable. The spells aren’t based on incantations, but... the characters augmentor works kind of like how a wizards staff would. It’s always on them, a personal item that channels their energy and allows them to create symbols that are woven together and thus magical things happen. The character doesn’t need to verbally say anything to cast a spell. An augmentor can be any solid personal object such as jewelry and anything like that. Keep in mind the size of it, you don’t want to be lugging around a hammer all the time... though you can if you really want to. 

I hope that answers your question!
