I believe it turns krolin into hardmode my friend.. before anyone pulls the boss, you use the extractor on him... he enrages turns into OP krolin... then you fight him... when the fight finishes you should either automatically get the item you need, or you have to loot the item.. but you need a full raid party to do my friend. He is pretty damn hard. I think when he goes into hardmode version he gots like 20 mil hp + idr tho
