Maddening Mural
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.

Trap: This strange painting threatens the sanity of those who wander too close.Perception     No check is needed to notice the painting.     DC 19: A character more than 10 squares away sees that the images in the painting twist and writhe. 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 trap’s psychic attack then lashes out at the creature in an attempt to snare and devour its sanity.Attack * PsychicOpportunity Action      Ranged 10
Target: The creature that triggered the trapAttack: +32 vs. WillHit: 2d8 + 10 psychic damage, and the target’s sanity is entrapped within the painting. While the target’s sanity is entrapped, the target is dazed and slowed and can spend actions in only the following three ways:    Stumble Away (Move Action): The entrapped creature cannot run.    Fight the Painting (Standard Action): The entrapped creature can make any at-will attack against 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. A successful skill check gains 1 success on a complexity 1 skill challenge (4 successes before 3 failures). After 4 successes, the painting is disabled. After 3 failures, each entrapped character takes 3d8 +10 psychic damage, and the skill challenge must be started again.
