we all know how it can be hard to even get an uncommen chest but where are the best places to find them?
As i know, almost every non-boss dungeon has at least 1 chest or box. GH dungeons have 2 (never seen with only one or maybe didn’t pay attention).
My advice, get the strongest, robust and fastest character you have and do a few runs in any dungeons that has mobs to which you can mostly do max or moderate damage. For example, Cretacious park with archer or VH. There are no mobs whith the defence against xbows or bow. Leeches can be tough though.
Just did a run on the CP with one floor in GS and found a common and rare. So any chests can be there.
For legendaries I prefer the last dungeon. But the chances are still small.
