Terrain Ability Earthquake
Gutsco is a pretty straightforward boss that likes to cast Fira. Ice Armor is effective for your Warrior, but the rest of the party will have to rely on healing to stay in the fight. You can try to Silence him, but his magic resistance makes it difficult. You'll have to walk or Teleport out after the fight.
