When is the earliest that set items drop during normal stages? I started a new character and I want to just leave him on a floor to farm.

It will only appear in equipment of perfect quality and above.

after 110 floor then set items drop may be.

im playing 3charater now. more character more fun LOL.

So how do you get set bonuses on t5 items? Farming dungeons cold take years. You have a chance to get the item you want, then a smaller chance to get the set bonus you want on that item.
