Blind Devourer
Trap
Level 15 Lurker
XP 1200

The fiendish visage carved into the floor stares up with blank eyes, the blackness of its mouth seeming to draw in all light.

Trap: The featureless black mouth of the blind Devourer is a trap that conceals the only exit from this chamber.Perception     DC 18: The character can see multiple signs of metal scrape marks at the edge of the blind Devourer’s mouth, as if armored characters had carefully lowered themselves into it.Arcana     DC 18: The character recognizes that the mouth of the blind Devourer is a fixed sphere of darkness, much like a sphere of annihilation.Arcana or History or Religion     DC 23: The character recognizes that this imagery is wrong—although the green diabolic face is Acererak’s most infamous symbol, it has never before been pictured with its eyes closed.Special       Until the sphere of darkness is disabled (see Countermeasures), the blind Devourer radiates no teleportation magic.
Trigger       When a creature enters the blind Devourer’s mouth, the trap attacks.
AttackOpportunity Action      Melee 0
Target: The creature that triggered the trap.Attack: +18 vs. FortitudeHit: 4d6 + 5 damage, and ongoing 10 damage (save ends). A creature reduced to 0 hit points by the sphere’s damage is destroyed and reduced to a pile of fine gray dust.Countermeasures     A character can make a DC 23 Athletics check to climb out of the blind Devourer’s mouth. Up to two characters adjacent to the mouth can aid this check.
     The sphere of darkness cannot be controlled or destroyed, but it can be disabled temporarily in the course of activating the exit from this location. A character can make a DC 25 Athletics check or make a melee weapon attack vs. AC 31 that deals 10 or more damage to break the carved stone of one of the Devourer’s blind eyes. The character who breaks the stone takes 1d10 damage from arcane feedback, but the sphere is disabled while the Devourer’s open eye is revealed. The stone that covers the area magically re-forms, restoring the blind eye in 1 round.
     If two characters break both eyes simultaneously, neither character takes damage, the sphere of annihilation is disabled for 1 minute, and a portal opens beneath it. Characters who lower themselves into the Devourer’s mouth drop 20 feet into location 2, taking falling damage as normal. Characters can lower a rope down to avoid this damage, but the rope is severed when the sphere of annihilation reactivates.
