Executioner's Chariot

The Executioner's Chariot is an optional boss in Dark Souls II. It is an undead two-headed horse that tortures the undead skeletons of the Undead Purgatory by smashing into them for all eternity.

Biography
During the Old Iron King's rule, he sent his knights out to round up the undead from his kingdom of Venn for sport. The Executioner's Chariot was designed to be used to torture the undead during these hunts. Long after the Iron King and his kingdom fell from fire and rock, the chariot continued its tradition of punishing the undead; but not under control of the rider, but his horse, possessing its rider's will with the intentions of tormenting its victims.

The Bearer of the Curse encounters the chariot in the Undead Purgatory, continuously running loops through a circular arena, forcing them down one way from the fog door, as the other way is a pit they cannot jump over. There are skeletons in the way that attack the player, although they can be crushed by the chariot. The skeletons will continuously revive unless the two necromancers that are hiding in two alcoves of in the arena are killed.

At the end of the looped arena is a lifted iron gate, which falls back down when a nearby lever is pulled. The chariot will be unable to stop in time and crashes into it. The chariot is destroyed, the rider is killed, but the horse is slightly injured and quickly raises back to its feet. It attacks by biting, stomping, kicking, or breathing out a dark flame. Defeating the horse ends the battle.

Alternatively, the horse can be defeated without lowering the gate by hitting it with arrows, spells, or a long-ranged weapon as it continues to run across the arena. As it weakens, it jumps the pit at a slower pace. Once it has less than a fourth of health left, it misses the jump and ends up hanging on the edge of the pit. Hit it once for the mad steed to plummet down to its death.

In the Scholar of the First Sin edition of Dark Souls II, a second horse can be found in a hallway of the Drangleic Castle.
