I actually do have 3 of every dub in my box, except amelits because I'm not sure I've gotten three total yet, and mythlits, because I keep using the third (to burn off all the extras) and being at two.My strat has been keep 3 dubs of each type in your box... then when you do need a specific one... farm THAT high level dungeon when its double drop rate... gives you xp fodder and not a complete waste of stam if you dont get what you want... dub mythlit has been a bit shy recently though...
I'm just not far enough along yet. I guess that gives me a goal for this weekend, though... I wonder how far in normal i can go if I actually put forth a concerted effort.
One way to find out!
