correct me if i'm wrong but u need 333 of each basic item:
SoulAroma+Moss+DreamGrass=GhostHorn = 1 of each
3GhostHorn=1EvilTooth = 3 of each
3EvilTooth+3SoulAroma+3Moss+3DreamGrass=3FeatherSt one = 12 of each
3FeatherStone=1ImmortalStone = 36 of each
3ImmortalStone+3SoulAroma+3Moss+3DreamGrass=3Vigor Fragments = 111 of each
3VigorFragments=1ImpureVigor = 111 of each
1ImpureVigor=1PureVigor = 111 of each
so as you need 3 pure vigors then 111 x 3 = 333 O_o thats a lot. Total 999 basic items, we can say 1k
P.S. i need 1 moss then i go make vigor fragments.. blah blah and my second pure vigor will be ready
