StrategyThe Blood Iron Eater spawns when you harvest out all the blood iron ore veins in the mine.[]
Damage-out-put is ~300k every 3sec (crush), BUT during the fight The Blood Iron Eater casts "enemy mining" (?). You have to cure this poison immediately (start cure in the last 20% of the cast-bar of The Blood Iron Eater), as The Blood Iron Eater runs away and if you are too far away you will instantly die.
