What little i have been testing Torghast in beta i have been getting 3 types of boss/chest loot: orange quality legendary “[PH] lengendary component”, epic quality “[PH] comdemned soul essence” and epic quality “[PH]Torghast boss loot”. Legendary component only has been dropping from end chest but boss loot also from end bosses. Besides those basic mobs and things you trash give you currency you can use to buy more skills (expires on exit, not saveable) and grays and bit of gold. But yeah there is placeholders for “boss loot” dropping from there right now.
I think it’s good thing Torghast drops actual loot, it provides nice gearing option for both solo and group players. I hope it remains the same and that those “boss loot items” are actually usable gear and not turn out to be something useless.
