Yep. She had no other gimmicks or powers beyond the standard meguca package, either. Superhuman, but not especially strong or fast by meguca standards. Her wish magic was also tied to her sense of morality; even in the heat of the moment, she literally couldn't use it on someone she didn't truly believe had done something to warrant death.
When her wish magic was active, though, she was untouchable and perfectly accurate with every strike. Like, she'd been meguca for not even an hour when she killed four experienced veterans by slicing their Soul Gem rings apart without drawing blood.
She wasn't invincible against direct assault by any means, but for a long time she had Kyubey guiding her and making sure nobody ambushed her or whatever, and by the time she turned against Kyubey she had enough experience and reputation that it would have been very hard to take her out.
