update:
Getting efficient XP and leveling is proving to be really difficult.
I've beaten nightmare now, at level 33.
They say the maggots in river is supposed to be where you level, but the xp is honestly fucking trash
Cows xp is trash, norm xp is trash, nightmare river is trash, I don't even know what to do at this point honestly
I've been leveling in nightmare river, to the point where I barely want to play this anymore. and doing cow king for drops
FINALLY successfully gambled
