Fine so she's partially affected, then what? How can she know Set's used this spell? It is also still optional for you to use that. No one said you had to, and it has nothing to do with being IC. That is a MUN's choice. It isn't as if she's a terrible fighter, and it would be IC for her to get punched if someone tried to hit her. This is a spell that Set very well could have fucked up, he has a history of being terrible at spells.
