grind mimics using demon layer
it worked for me
after you reach high level everything you do will can pretty much "kill" anything
Thanks
the labyrinth is also an option (with nightmare mode) but personally i do not use it because it is very laggy
Yeah i agree mimics are better because they are easier to defeat and you don't have to fight like 100 enemy's to get some exp (personally have not play labyrinth nightmare mode)
