Ogest

The first fight, in , is not really a hard fight, but it is a long one. You only need to get him down to 49% and he will run away. His Ranged damage is not all that bad but his Melee attacks are very strong. Oddly, he will not choose to close to Melee range, preferring to stay where he is.
The second fight is not much harder, but there are 4 bosses you have to drop to enter the throne room.
