Dirty Colossus

Dirty Colossus can’t touch you while his facing the opposite direction. Use melee and approach his back and then go all out with physical attacks. Dirty Colossus shares the same weakness to fire or dragon weapons with the Leechmonger boss. That being said, use Turpentine to endow your weapon with the fire property or equip a Dragon weapon or a light weapon.
