Goliath

Order of Ecclesia
Goliath appears in Giant's Dwelling as the game's 6th boss. This is considered to be the hardest boss fight of the whole game. Not only is Goliath powerful, but his attacks are imbued with magic power. When he punches the ground, spikes made out of rock will erupt out of the ground. Sometimes, he will jump up and slam the ground, causing a giant shockwave to erupt around him. He will also punch the ceiling, causing easily destroyable debris to fall and hit you. His most powerful attack is taking long strides to back you into a corner. You can crouch under his strides to avoid the attack, but if you are backed into the corner, he will keep punching you until you die. This fight will take awhile, so make sure you equip your most powerful glyphs.
