Boarinot's job is to make sure that no one gets in the way of Corruption. Any Pure monster will automatically become a mortal enemy to him. He may be as smart as a stick, but the fact that he doesn't ask questions and just attacks makes him the perfect ally for the Lord.
Boarinot is a Magic Tank who can Heal himself and recharge 50% Stamina in one go, Double his Maximum Life, or gain Double Healing while he deals damage to an enemy. He has an Evolving Trait: at rank 0, he has Taunt, at rank 1, he gains Immunity to Stun and, at rank 3, he gains Damage Protection at the start of every battle.
