You completely surround a Large or smaller creature in immobile illusory walls, trapping it inside a false prison it can't escape. No other creatures see or feel these walls, and the target can't see anything outside of the illusory walls. The target can attempt a Will save when the spell is cast, each time it attempts to interact with or escape the walls, and each time something from outside the walls affects the target. On a success, it disbelieves the illusion and the spell ends.
Heightened (8th) You can target up to 5 creatures.
Traits
An action with this trait requires a degree of mental concentration and discipline.
Effects and magic items with this trait involve false sensory stimuli.
An ability with this trait can take a character completely out of the fight or even kill them, and it's harder to use on a more powerful character. If a spell has the incapacitation trait, any creature of more than twice the spell's rank treats the result of their check to prevent being incapacitated by the spell as one degree of success better, or the result of any check the spellcaster made to incapacitate them as one degree of success worse. If any other effect has the incapacitation trait, a creature of higher level than the item, creature, or hazard generating the effect gains the same benefits.
You must physically manipulate an item or make gestures to use an action with this trait. Creatures without a suitable appendage can't perform actions with this trait. Manipulate actions often trigger reactions.
A mental effect can alter the target's mind. It has no effect on an object or a mindless creature.
A visual effect can affect only creatures that can see it. This applies only to visible parts of the effect, as determined by the GM.
