Auto-Reflect

Auto-Reflect is a recurring ability that permanently puts the user in Reflect status. This guarantees that the majority of spells cannot harm the user, but also means the user cannot benefit from positive spells, or even be cured by healing spells, up to the point that they cannot be revived with Raise spells. The effects of Auto-Reflect cannot be dispelled. It is usually granted by the accessory Reflect Ring or the armor Mirror Mail.
