The other Yue Qiluo was weaker because she was sealed by a very evil way for hundred years... making her body vulnerable to anti-evil spells - thus as an assassin she was weak to casters.

This reincarnation of her ... her origins, and objectives are still a mystery(because it was late and I cannot continue building the story for her ... gotta work on that on the next few days)
