@Pirouette@PirouetteOh goodie, a poison based character. Time is this character's friend it seems, a bunch of debuffs that lead up to a final attack. But it is neat to see it is in fact harmful to her, and that she needs to be judicious early on to get the full range of powers. You've already addressed the main issue the other GM's have had, with Death and Decay's permanency, which is good. So long as the damage isn't permanent, at least to PC's, we're good. I also like the idea of it being a good weapon against Mori too, since as written it does seem it would affect her too. I like this moveset and fighting style. Take her down quick or you're in a world of pain.
I like the backstory , with the combo of tech and magic. I can certainly see some great sympathetic moments for her, and as Kai said, she is a bit of a woobie. She's got my stamp of approval.
