This spell reveals each round whether an illusion is active on a targeted creature (or placeable, or area with Dungeon Master guidance). If the target is under the effect of a non-detection spell a secret check is first rolled to determine if the divination can proceed. If it fails the caster learns nothing more.

Upon success the caster will silently roll against illusory effects on the target. Hostile projected or illusory images are affected whenever the caster targets them, prompting the caster of said images to roll a willsave vs spells against Detect Illusion's spell save DC. If he fails the illusion is dispelled.

When a target has active mirror images then that spell's casterlevel is compared against Detect Illusion's spell save DC. If the casterlevel is lower than the spell save DC the affected spell is supressed for one round. Spells of level three or higher, such as displacement, are not supressed or negated by Detect Illusion.
