Star Ocean: The Last Hope International

This is the boss on the first visit to the world Lemuris. He's a bit hard, but the enemies in his area are really easy to grind if the player needs to gain a few levels before him.

He does have a weak spot on his tail (blindside him if needed) and he does have a few big attacks, but overall he's easier than the first boss of the game.
