That's my main beef with this game for now. I hope a similar utility comes out soon for Grim Dawn. It effectively gave you unlimited storage. There was a great utility program for Titan Quest, I forget the name, but it basically allowed you to empty your stash into some sort game files, and restore them with this program. There is nowhere near enough stash space in this game. I just want to get into Ultimate with some character and start farming legendaries. I started him off as a summoner/pet build, but that was really boring (though powerful early on). He's a melee, 2H Primal Strike build now. I also have a lvl 63 Conjurer (Shaman/Occultist). I've died like *gulp* 45 times or so, last I checked. He uses two guns and does great offensively.
I have a lvl 65 Sorcerer (Demolitionist/Arcanist), that is in Elite.
