[quote=@Turboshitter] What sort of personality issues do you foresee? Some conflict between Masters and Servants can be fun, after all. Also, does doing this hurt her body at all? Like does it have a time limit? I don’t know what the exact rules would be for lesser spiritual beings but a human allowing themselves to be possessed by a Servant will explode in like half a second under normal circumstances. Perhaps an interesting limitation on her combat abilities could be that they are effective but short-lived? [/quote] [@Turboshitter] The boring kind, as in, like Tokiomi's relationship with Gilgamesh levels of boring. Also, I've also been thinking about a hazard to add besides a time limit one and I'm torn between the limitation being the degradation of her Magic Circuits (which fits into the Mather's family magecraft being a hazardous thrown together thing created after Gregor and Crowley fucked up everything) or degradation of her mental faculties (the allowing a spiritual being noted to be beyond human understanding to enter one's body shouldn't be healthy to one's mind) the more time she spends channeling an Archangel. In your opinion which is better?
