D'Sparil

D'Sparil is the main villain and final boss of Heretic, and is the boss of Episode 3: The Dome of D'Sparil. He is the first and the youngest of the trio of Serpent Riders, relying on cunning and deception to initially gain dominance of Parthoris, the world of Heretic. He declared the supernatural race of the Sidhe to be forever hunted as heretics to their new Order. The Raven sequel, , begins with D'Sparil's death and shows D'Sparil cursing Corvus.

In Game
D'Sparil initially is seated upon a Green Chaos Serpent, which are prevalent in Hexen. The Serpent is the most powerful of any Chaos Serpents in the series itself, able to belch fireballs, at first in single units, and then after falling below half its health, shoot a line of three scattered fireballs at the player. The Serpent can also make a bursting charge of speed towards the player when stunned by attacks. Like the Iron Lich and the Maulotaur, D'Sparil is immune to the effects of the Morph Ovum and cannot be instantly killed by the Firemace under the influence of the Tome of Power. D'Sparil also has 50% damage resistance against the powered up Hellstaff's rain like the Maulotaur. He also takes no splash damage from explosives. When the Serpent dies, D'Sparil will electrify and rise up, and start attacking the player. His abilities are a mix of offensive and defensive tactics, one being to fire a blue, trailing bolt of electricity for extreme damage to unarmored players. He can also shoot a pair of purple rings which turn into Disciples of D'Sparil, and teleport himself to one of the six raised platforms in the area. As he is damaged more, he will teleport more often. D'Sparil will also often teleport when he is hit by a Phoenix Rod missile or Hell Staff rain (the game code does a specific check for these weapons hitting him).

D'Sparil can be hurt by stray missiles from his disciples, however, he will not retaliate against them in infighting when in his dismounted state. His chaos serpent has no such qualms, however.

When D'Sparil finally dies, he explodes into a pile of bones in a burst of electrical energy, and all the other enemies on the level will instantly die too.

D'Sparil's entire fight is 5500 Hit Points; 2000 Hit points for the Chaos Serpent, and D'Sparil himself having another 3500 Hit Points.

Battle Sounds
The demonic incantations of D'Sparil are actual phrases recorded backwards:
 * SORSIT - This sound is hard to understand, but some possible interpretations are "Now ravens shall chew your flesh" and "I will torture your flesh"
 * SORACT - "Surrender to D'Sparil"

Trivia
A reference to a Tomb of Desparil can be found in the title of the twelfth level of Catacomb II, a game John Carmack wrote for Softdisk in 1991.
