Ok, so, I want to lvl up as fast as possible, how can I achieve this without doing every single quest in the game?
thanks in advance guys 
Also, i have both expansions (ummm i think. Crucial and AoM)
Ugh… doing all the optional quests as you get to them is a fantastic way to get xp.
in this game you pretty much can always rely on quests to give you a good amount of xp but in case you already unlocked the homestead area you can go there and farm the dermapteran queen hive and the twin falls for some decent xp
I see. So basically there is no such thing as power lvl… got it Also, how do you do crucibal? I have tried to do it, but spans keep killing me at 3rd or 4th wave
you gotta find some good armor and maybe put more points in 1 skill so you can deal damage to clear waves more efficiently
Power leveling is knowing where the quests are, and making a beeline to them. That and stopping by all the bosses for a chance at good gear drops.
Once you get to about 40, doing the Undead Rogue zone is good experience and loot.
thanks man
