Steps:
i'm doing the "method in his malice" quest for the WAR zodiac weapon. this is the quest where you need to retrieve 4 vials of blood from 4 instanced dungeon bosses. first is the tonberry king blood, from the wanderer's palace. second is the hecatoncheires blood from copperbell mines (Hard). third is the kraken blood from hullbreaker isle. this is where i'm up to in the quest. ive turned in the two previous vials, and the npc directs me to hullbreaker isle for the next one. , but i went to check the journal entry for the quest, and the next step listed is to turn in the hecatoncheires blood from copperbell mines (Hard) to the NPC. this was already done. i even went back to the NPC, he does not ask for that anymore.
