Force Burst Wall
Trap
Level 5 Obstacle
XP 200

A flaring, translucent wall of blue force hangs like a sheet of wavering glass, blocking access between the corridor and the stone chamber vaguely visible on the other side. The chamber on the other side is empty but for a single closed door.

Trap: A field of force explodes outward when the trap goes off.Perception     DC 18: The character notices the squares in front of the wall are trigger plates.     DC 22: The character notices the hidden control panel set on the left side of the wall. The control panel contains only a single keyhole.Initiative +7TriggerWhen a character moves into a trigger square, the wall attacks with a burst of blazing blue force as an opportunity action. Then the trap rolls initiative and attacks as a standard action each round thereafter.AttackOpportunity Action/Standard Action      Close burst 2

Turning it the other direction allows the trap to attack again as a free action. Success disables the trap.
     Arcana DC 22: (Standard Action) Six successful checks made on the control panel disables the trap.
     A character can attack the wall (Defenses 5; hp 100) or the control panel (Defenses 12; hp 60). Destroying either disables the force burst wall.
