Arth's first spell. It strengthens Arth's sword for a short time, allowing him to deliver a mighty slash to the enemy. It was first used to attack Gani Fest, after Elly had repeatedly refused to help Arth. Saving Arth by casting spell convinced Elly that she could still do good in her life even with her disease, and she decided to become his partner. This is seen in a flashback, and the spell is not used in any of Arth's present-time battles.
