Details
Since this is a field with unusable items, some items cannot be used. Some attacks will reduce the Awakening gauge. You can break it with 2H Spear skills. When its HP falls beneath a certain amount, it changes mode. When it changes mode, it receives a buff. Additionally, its Break conditions change. Skill Breaks can be performed with skills that are both Thrust Element and Fire Element. With each Break or Skill Break, it will be weakened by a stack debuff that increases damage dealt from players. In the Character Quest and Labyrinth, at the beginning of battle, it grants a "Critical resistance" and "Reduces damage" buff. It uses the "Increase Defense" buff. It uses the "Seal item" debuff.
