Here is the thing:
Neith’s innate resistance says it’s against ailments that stop mana generation, but Onatel’s ailment does not stop mana generation (like for example Proteus), it steals mana partially (25% of mana for the first turn) but as for now — Neith always resists it, like it would stop her mana generation, while it actually would not.
I think it’s a little mistake
