Diabolos was a powerful Voidsent, summoned to Eorzea by the Voidmages of Mhach during the Fifth Astral Era. In the waning days of the era, during the destructive War of the Magi, he was sent to attack the city of Amdapor. He destroyed the city, but the White Mages of Amdapor magically sealed him in the ruins. Thus confined, he slept for the ensuing centuries.

SPECIAL ABILITIES
Dark Messenger (Su)
Once a day, under 50% health, as a standard action, Diabolos conjures a black hole of dark energy, blasting his foes. Enemies within 30 feet of the avatar take 15d6 points of shadow damage, with a Reflex save DC 29 for half.
Giganton Press (Ex)
Diabolos fluctuates the gravity around himself within a 30-ft.-radius aura, knocking all enemies prone and applying a free grapple attempt if nearby him unless the enemies makes a Fortitude save DC 29. The grapple is held as though it had a bonus of +26. A creature that saves cannot be affected by this Diabolos’ Giganton Press for 24 hours.
Pit of Dispair (Su)
Diabolos creates a blast of dark energy against a single foe. The target of this ability suffers the effects of Gravity, as the black magic spell. Blue mages may learn this ability as a 5th level spell (Knowledge: Planes DC 25).
Shadow Strike (Ex)
Once every 1d4-1 rounds as a standard action, Diabolos can make a slam attack by striking a shadow adjacent to him and hitting a foe up to 30 feet away. He has a -5 penalty on the attack roll with this ability but the foe is considered flat-footed against the attack.
Corruption (Su)
3/day, Diabolos whispers words of taint and corruption to one foe up to 30 feet away. The subject must make a Will save DC 29 or be inflicted with Confuse status. Blue mages may learn this ability as a 6th level spell (Knowledge: Planes DC 27).
Nether Blast (Su)
As a standard action, Diabolos can send a blast of pure nether, requiring a ranged touch attack roll (+28) against a target within 30 feet. If the attack is successful, the target takes 5d6 points of shadow damage and bypasses 10 shadow resistance also does 10 points of shadow damage to anything immune to shadow.
