SQ amphibious, change shape (humanoid and serpentine; shapechange)
Creatures that strike Geryon with melee touch attacks, unarmed strikes, or natural attacks are exposed to its poison, as are creatures that confirm a critical hit on Geryon with a piercing or slashing weapon in melee.
Geryon is immune to the effects of the River Styx and to all effects that cause memory loss or manipulate memories.
Tail slapâinjury; save Fort DC 43; frequency 1/round for 6 rounds; effect 1d6 Int drain; cure 3 saves.
Geryonâs vital organs and senses are spread across all three of its linked bodies. An effect that would cause it to become blinded or deafened instead affects only one of its bodies, unless it affects an area or targets each body as a separate creature. If one body is blinded or deafened, Geryon suffers no ill effects. If two bodies are blinded or deafened, it loses its all-around vision and is dazzled. Geryon is blinded or deafened only if all three bodies are blinded or deafened. It likewise has a 75% chance to ignore critical hits, sneak attack damage, and similar precision-based damage.
Environment any (Hell)
Organization solitary (unique)
Treasure triple (+5 arrow deflection bashing heavy steel shield, +5 cruel dispelling burst unholy flail, Horn of Lies, other treasure)
Geryon is a knot of three 20-foot-long, scaled worms.
From its maws it can partially regurgitate and speak with the voices of any being it has ever devouredâbe they mortals, fiends, or stranger eldritch beings. As a result of its covenant with Asmodeus, Geryon is now a true devil.
Slot none; CL 30th; Weight 15 lbs.; Aura overwhelming all
This horn can be sounded three times per day as a swift or move action to function as a greater horn of blasting with no chance of exploding and an effect duration of 1 minute. Creatures deafened by the horn hear whispers and falsehoods echoing in their minds, twisting their perceptions; they treat all other creatures as if they had concealment and take a â4 penalty on saves against mind-affecting effects as long as they remain deaf. In addition, any competence or insight bonuses are treated as penalties instead until they regain their hearing.
If these 13 serpents are slain within 24 hours, the artifact is destroyedâbut if even one serpent remains alive, the Horn of Lies is restored and returned to Asmodeusâs keeping in Hell.
Geryon is worshiped by those who crave forbidden knowledge. Its sacred places are hidden within libraries or amid the ruined temples of nigh-forgotten gods and fallen kingdoms.
Geryonâs unholy symbol is a shadowed, red-and-black serpentâs head. It favored weapon is the heavy flail. It grants access to the domains of Evil, Law, Strength, and Water, and to the subdomains of Devil, Ferocity, Oceans, and Resolve.
