Vercingetorix is the final Cie'th Stone mission boss in Final Fantasy XIII and is one of the Undying. The Cie'th Stone required to accept the mission is available after beating Missions 27 to 51, and after beating Barthandelus in Oerba. The Stone is found at the end of the broken railway bridge in Oerba, where Barthandelus was fought at the end of Chapter 11. The Cie'th Stone and the mark are on the furthest opposing ends of Gran Pulse: Vercingetorix is found in Yaschas Massif Paddraean Archaepolis. Vercingetorix can be considered the game's strongest foe.
Vercingetorix is a flying enemy similar to related enemies Mithridates and Bituitus. He has two wings but the lower his health goes, the more wings he sprouts. Whenever Vercingetorix reaches one of his HP milestones, 90%, 60% and 30%, it'll sprout new wings and grow stronger, especially Vercingetorix's Wing Shear attack: with 2 wings it hits 9 times, with 4 wings it hits 15 times, with 6 wings it hits 21 times and with 8 wings it hits 27 times. Another attack Vercingetorix uses is Wicked Whirl. Despite Vercingetorix's attacks looking like Wind attacks, they are actually non-elemental.
Vercingetorix continually casts Impenetrable Aura on itself, becoming immune to damage and recovering health. The amount of HP it recovers is [(Max HP - Remaining HP) * 0.01] x 8. The recovery removes status ailments and adds Bravery; with four wings the recovery skill adds Faith; with six wings it adds Protect; and with eight wings it also adds Shell.
After 30 minutes of battle time Vercingetorix will cast Doom on the party leader.
Before the battle the characters should be well developed in the Crystarium (all of them should have Sentinel and Medic), and it is highly recommended to have the Crystarium maxed out for everyone. Equipping damage reducing accessories, such as Imperial Armlets and Royal Armlets, is advised, and the extra ATB slot granted by the tier 3 weapons can be of great help. One should use Fortisol and Aegisol before the battle to make the fight easier.
It's best if the party includes characters who know Poison and Dispel. The recommended paradigms are Infiltration (SAB/SAB/SAB), Tri-Disaster (RAV/RAV/RAV), Relentless Assault (RAV/RAV/COM), Rapid Growth (SYN/SYN/SYN), Salvation (MED/MED/MED) and Tortoise (SEN/SEN/SEN).
The party should start the battle with Infiltration, and either cast Libra, or use a Librascope so the AI will know what to do. The aim is to cast as many status ailments on Vercingetorix as possible, especially Poison, which constantly damages its target's HP by draining a constant percentage of the target's total health. Because Poison takes off a fixed percentage per time regardless of number of hit points, it is especially advantageous on enemies with high HP, such as Vercingetorix. It is even possible to win the battle with just the help of poison, shifting to a healing/defensive paradigm as soon as Poison has been inflicted.
If the party succeeds in casting the debuffs, they should paradigm shift to Tri-Disaster and start filling Vercingetorix's chain gauge. Vercingetorix is difficult to stagger despite a low stagger point, because he casts Impenetrable Aura. If the party staggers Vercingetorix, they should shift to Relentless Assault to further fill his chain gauge and deal damage. Should the words Wicked Whirl flash on screen, the party should immediately shift to Tortoise to take the damage, and then to Salvation to heal.
Vercingetorix will use Impenetrable Aura, which makes him invulnerable to damage, clears him of status ailments, and empties out the chain gauge. The party can use this time to heal and rebuff. Vercingetorix will heal 1% of the damage dealt to him, eight times, and then come back.
The player should not ever think twice about healing; should any character need HP, the party should switch to Salvation, even if the mark is staggered. That can save Phoenix Downs (Phoenix Downs are better than Raise). The battle is easier if the player deploys a Saboteur to dispel Vercingetorix's buffs whenever he comes out of his immunity.
Players can find it difficult to survive when Vercingetorix has sprouted all of its wings. If this is the case, the player can use Vanille as party leader. Vanille is the only party member who knows Poison and has an Eidolon with an attack requiring the use of just one unit. The party can stomp Vercingetorix down to low health (at around 5 million HP, or 10 million if the party has an Elixir), then poison it, summon Hecatoncheir getting a reasonable Gestalt Bar, then going Gestalt Mode and not doing anything, which makes Hecatoncheir use only Chain Cannons, hoping that Poison will kill Vercingetorix before Vanille runs out of time counters. This is an effective strategy that almost guarantees a five star battle rating and operates on the idea that Poison still affects the target while the player is in Gestalt Mode. Vanille is best equipped with her debuffing weapon (Belladonna Wand and its upgrade Malboro Wand) and go for the Gestalt Boost synthesized ability (Speed Sash, Energy Sash, Champions Badge and Survivalist Catalogue).
Vercingetorix was a chieftain of the Arverni tribe during an unsuccessful revolt against Roman Forces during the last stage of Julius Caesar's Gallic Wars.
