Maddening Mural
Trap
Level 29 Warder
XP 15000

A seemingly normal landscape is carved into the wall, but the more you look at it, the more you spot strange details. Images of vegetation hide eyes, mouths, and claws, and the shapes themselves start to twist into horrid monstrosities that reach out from the mural, lashing at your sanity.

Something is definitely strange about the painting.Arcana     DC 33: The character identifies the painting as a maddening mural and knows the risks of getting too close to it.TriggerThe trap is triggered when an enemy ends its turn within 10 squares of the painting.

The attack deals damage to the painting’s physical statistics (see Countermeasures).    Free Itself (Standard Action): A DC 19 Intelligence, Wisdom, or Charisma check frees the creature from the entrapment. When a creature frees itself from the prison, it is still dazed until the start of its next turn.Countermeasures     Arcana DC 28 or Thievery DC 28: An entrapped character who is trained in Arcana or Thievery can use a standard action to attempt to disable the painting.
