I've been farming Scourge of Winter story boss. Get the checkpoint outside his chamber. Pop coin, snipe boss low, run in and rocket suicide to kill him. If he dropped loot, it'll still be there. Rinse and repeat. Within 15 coins, I've gotten 3 chest exotics. Edit. 31 coins, 5 exotic engrams. Roughly half hour of . Mission - Scourge of Winter[b] (Difficult doesn't matter) [/b] Pop coin. Snipe boss low, or shoot him, whatever works for you. Go in and kill him and yourself with a rocket launcher. Any loot will carry over after you revive at the checkpoint. Rinse and repeat while collecting any loot drops from the previous kill. [b]Only use one coin at a time,[/b] the buff goes away regardless of you getting a drop or not. [
