the last boss was easy for me...I'm a lvl 34 archer....due to making 3 fractions an ally....the trick I did was use frost shot at him then....continuously attacking him...then if the frost effect went down shot him again...until he dies
I love the ranger...it's so cool killing those warrior type enemies...my only problem is the ranger type enemies.....especially when they are two of them...and it's hard to level up...as for the items...I just keep on killing enemies and loot them up...
