Well Deaton is being totally shady and not really explaining it, but the best way I can explain it is that I’m kind of a mage. With like spells and things, but instead of spells is more.. using emotion, power of belief. Because I’m a spark, I need a catalyst, and while taking energy from within can be draining (both literally and figuratively) It’s easier for me to use the magic that naturally surrounds supes. Kinda like an alpha, I can draw on supes but they don’t have to be in a pack with me. It’s mostly meant for defensive magic, the more supes invading the stronger it gets, but it can be for offence (A good defence is a good offence?) though Deaton won’t teach me how to harness my power into anything more than protection, healing, and barrier spells.
