Spell: Labyrinthine Prison
This ritual was developed by a long-dead minotaur hero-god whose cult trained to hunt and trap evil beings. It creates a maze of ever-shifting warped space woven from intertwined demiplanes that twist in ways few can solve.
You and the secondary casters draw a maze of twisted space into being with the target at its center. An unwilling target must be Immobilized, Unconscious, or otherwise prevented from leaving the area for the entire casting time, or the ritual fails. An unwilling target can attempt a Will save to resist the ritual; on a critical success, treat the result as critically failing to cast the ritual. While the target is trapped within the labyrinthine prison, they cannot escape it, as even abilities that give access to other planes are subject to being twisted into the maze. Instead the only way to escape is by succeeding at a Maze Lore, Perception, or Survival check against the labyrinthine prison's DC. This check can be attempted once per week, and the first check can only be attempted after a week has passed. If all casters spend one Mythic Point each, this interval changes to one year, and the DC uses the primary caster's mythic proficiency.
Critical Success As success, and the twisted space renders the target Stupefied 2 while within.
Success The target is trapped within the labyrinthine prison for the duration of ritual.
Failure The ritual fails to trap the target.
Critical Failure As failure, and the casters are all Stupefied 4 for 1 week.
