I had a backup mag mod and thought that was great but Rampage Spec is the only mod that gun needs. The full extra second of Rampage makes all the difference in the world. Easily stays procced during reload now and makes keeping 3x much longer.
The gun is even more devastating than it already was.
Random drop?
Just like with the first three forges, just as the second round starts, there will be two small drones that spawn at two set locations of the arena. It would be kinda hard to explain in writing here where they are but there are plenty of video's that talk about it.. i believe Datto has one. If you kill them both, a chest will spawn near the forge after you beat the boss giving you the key.
I know I've seen that... is there any way I can check in my inventory or somehow to see if I have done that particular step? Probably a dumb question. I know I'm mostly up to speed otherwise.
That rare bounty I'll easily get done in the next handful of days or so.
