Hello, It's the 2nd time I loot an exotic gun with 160 ( while I am around 280). There is no other options to increase it except some "increase Damage" perk which gain only 2 or 3 point. The very last "increase damage" require an exotic gem (not sure of right english word) I was wondering if this one will like double the damage or what? I mean I dont want to loose my gem for 5 points What I call gem is the green stuff you get from exotic disassembly.
