Where does the Damage +15% / -1 Energy Regeneration come from? I've been playing this game for 154 months and this is the first time I've looted an item like this. It's an old Inscription/Mod I take it, before they got added to the game with Nightfall? Is it just another version of the dual leech I just haven't seen before?
