Hmm... umbral marrow x5 (85m) or riftdross x60 (18m). When will the devs admit how horribly they screwed up the weapon hierarchy. They said empyreans were supposed to be the hardest to upgrade 95>99, but in "reality," they cost about a fifth of what a relic costs to upgrade to 99. Not even close guys! Golden Gobbiebag II should be changed to 1500 heavy metal plates (150m+).
