You could try out the devour build instead of stormcaller, I haven’t played much as a warlock but I think the devour build is real strong.I just got this game for Xbox yesterday. I had the original and enjoyed it for a time but got quickly bored when no one I knew played.
Now I've got some friends who might be interested so I'm giving it a shot. I'm going for a Warlock Stormcaller because it seemed really cool when I unlocked it last time. Anything I should know before really diving in?
