Hecatoncheir (Final Fantasy XIII boss)

Hecatoncheir is a boss in Final Fantasy XIII. He is Vanille's Eidolon, and is fought by Vanille and Fang in the Mah'habara Subterra's Flower-filled Fissure, as a test to prove Vanille's strength to him.

Strategy
Like all Eidolons, Hecatoncheir inflicts Doom on Vanille at the beginning of the battle, and instead of being defeated, Vanille must fully fill up his Gestalt Bar.

Hecatoncheir is fought with only two party members, making the battle a bit tricky. By pausing the game and selecting "Retry", the player can set the Paradigm deck before battle. Recommended Paradigms include Divide & Conquer (SAB/COM), Stumbling Block (SAB/SEN), Lifeguard (MED/SEN), and Slash and Burn (RAV/COM). Hecatoncheir is immune to any of Fang's Saboteur abilities, so Fang should be a Sentinel for most of the battle. Hecatoncheir goes through stages of charging and attacking. When he is charging, the party can use offensive Paradigms but Fang must switch back to Sentinel when he starts attacking, lest Vanille be attacked or even KO'ed. If Fang has learned a few Ravager abilities, Dualcasting (RAV/RAV) can be included to quickly increase the Gestalt Bar. However, the player should make sure to have used Fang as a Commando to stop the chain gauge from depleting too fast, and switch to Dualcasting to build up Hecatoncheir's stagger meter. As noted before, it is a good idea to attack relentlessly, if the Eidolon is charging using Looming Wrath.

Also, using a Fortisol immediately before the battle will allow both characters to begin with the Haste effect. This makes it much easier to fill the Gestalt gauge before the Doom timer runs out.
