ahaha yeah, lvl42 for a fighter is easy. Even if you have a pure end build :P I used to have all end D: at around lvl40, then I started adding str points. (I regret putting 36end points D
goblins are just too easy for fighters, perhaps a little hard for mages, but those are so easy for all classes. And just like _The_Noob_ said, just wait till you get to lvl49 (painful to lvl to 50 D: but since you can easily enter lvl50 abyss now...shouldn't be too hard), lvl52 (really sucks to lvl up to lvl53...) and lvl56 (By then, you'd have 1 quest left lol)
