Leonora's response to Yuffie involved using Libra to see what if anything the creature would be weak to. She was fortunate the spell worked at all and most of what she got from it was weaknesses. "Try anything fire, wind or holy."

Most undead would succumb to healing magic so that was of course her first course of action, only to find it healed the monster instead. Leonora frowned, concentrating her efforts on preparing Holy instead, and did not catch that Lich countered her magic with Doom for herself.
