Absolver

Story related, can't be missed.

Kuretz is one of the main bosses of the game and is found in the Raslan Coliseum. The fight is in three phases, the first simply being a straight up 1v1. The second phase sees him being defensive, whilst sending his allies to help him. Defeat them all and you will enter the last phase which is basically another 1v1 but this time he will use his gauntlets against you. The gauntlets will do a good amount of damage to you if you are hit so time your attacks and he will soon fall.
