Impossible Labyrinth

Tier 2 Epic illusion

Casting Time: 1 action

Range: Self (120-foot radius)

Components: V, S, M (a glove from a goblin king)

Duration: Concentration, up to 1 minute

You generate a selective illusion of an impossibly complex labyrinth in a 120-foot cube centered on you. When you do so, you may choose any number of creatures of your choice to be immune to the effects of the spell for its duration. All other creatures in the affected area when you cast the spell must succeed on an Intelligence saving throw or become trapped in the labyrinth, hopelessly lost, wandering its impossible corridors in a subversion of physics. While lost in this manner, a creature cannot leave its current space (even by magical means), and other creatures in the labyrinth are hidden from it (detect DC equal to your spell save DC). At the end of each of its turns, an affected creature can repeat the saving throw, ending the illusion for itself on a success. A creature with truesight has Epic advantage on saving throws against this spell.
