Sa was the first exotic bounty I ever completed. I was still a noob at the time and knew nothing about what weapon I would get for completing it. I got it and it was awful. I decided to give it a shot and upgrade it, I didn't think it was worth the exotic slot. About a month ago, I needed more vault space after HoW dropped, and I sharded it. If your looking for an exotic shard, this is the weapon for you.
