Yeah her elemental spells don't do anything with that and elemental blessing does something similar I think but she has some non-elemental stuff like poison nova that'll still kill you. At least, I assume. given that it did like 900k damage I assume there's some sort of gimmick involved so you can get by it without it killing you aside from immortality but I never really figured it out. Although that late in the game there may not be a gimmick and you're just expected to have some immortality stuff ready. There are some blessings and armors/accessories that do it I think on top of Ray being able to cast it so it's not impossible.Damn, it's been a hot minute since I played this, but once you unlock the above-level-6 items, there's a shield (Black Hole, iirc) that basically stops all magic from doing anything to you. Equip that and Grand Magus cutie-pie is a harmless piece of meat just waiting for your punishment....
