Gilgamesh (Type-0 boss)

Gilgamesh is fought as the end boss to The Clash on Big Bridge mission. The battle concludes the mission even if the player loses. He appears as an optional boss with his traditional eight-armed appearance after the player has beaten the game twice and completed the second side-history missions. After the mission "The Last Queen Returns to Oblivion", the door to the Rift will open if the player completes all training missions to unlock map areas. The door will appear in four locations: Black Tortoise Crevasse, Militesi Empire near the capital, the Kingdom of Concordia near the Royal Palace and east Rubrum; the locations repeat in this order if the player fights and defeats Gilgamesh. Hence True Gilgamesh has a chance of appearing in one location in each of the four Crystal states.

Battle on Big Bridge
Gilgamesh is on LV65 and strong. He uses a spinning attack where he uses his enormous sword to strike those close to him. When nearby, he can grab a cadet by their neck and then strike with his sword. He moves failt slowly, but he has a lot of HP.

Strategy
It is possible to take Gilgamesh on even if he is on a much higher level than the player by exploiting the Breaksight strike chances that trigger when he is about to start an attack. On the last few HP bars the player can deal Breaksight strike many times in a row, quickly depleting his HP. It is best to use a ranged cadet and stay out of his way. Breaksight strike stops Gilgamesh on his tracks briefly.

True Gilgamesh
Gilgamesh will take a random party member to fight and if the player is defeated, he takes the character's equipped weapon. The reward of defeating the True Gilgamesh is the character's ultimate weapon.
