In this one, we're trying to turn badass swordswoman Helena into a slutty bimbo, the first step involves modifying her body, she might be powerful, but there's nothign she can do after the spell starts working on her.

Her hands turn into hooves, meaning she can't use weapons ever again, next her tits grow into proper udders as the slut should have, next her mind is assaulted by a shockwave that leaves most of women completely brainwashed by this point, so she would become docile and obedient.
