Level 15 Obstacle
XP 1200

Bloody manacles set into the wall come to life, rattling and grasping at you.

Trap: Manacles set into the wall lash out at nearby characters, attempting to bind them to the wall.Perception     No check is required to see the manacles.     DC 18: The manacles drip with fresh blood.     DC 23: The manacles quiver slightly.TriggerWhen a Small or Medium creature enters or starts its turn in one of the squares enclosed by the red dashed lines, the trap attacks that creature, attempting to bind it to the wall.AttackOpportunity Action      Melee 1
Target: Small or Medium creature in trapped squareAttack: +19 vs. ReflexHit: 2d8 + 6 damage, and the target is immobilized (save ends). Each time the target fails the saving throw to end the immobilized condition, the chains deal 5 damage.Miss: Half damage, and the target is slowed until the end of its turn.Countermeasures     Thievery DC 18: A character adjacent to the wall where the chains are set (or immobilized by a chain) can disable one of the four chains with a successful check.
     Each chain can be destroyed separately (AC 25, other defenses 20; hit points 30), which disables it.
     If four creatures are immobilized, the trap is full and can’t make more attacks. Reduce this number by one for each chain disabled.
