Another Fibber, Rubi or a DP Unkempt Harold would be a good choice, I think.
How do UH or Rubi work out? Don't you need to fire the fiber at the ground for the best results?
The Fibber breaks into multiple projectiles after initial impact, then ricchochets and deals increased damage. So fire it into the ground in front of him, so that it bounces up into him. The rubi converts damage into health. If you're using the fibber though, and firing into the ground, the second weapon will miss on all of it's shots while you're gunzerking.....so unless you're using 2 fibbers, that strategy won't be as effective.
No son, never. The blood stays on the blade. One day you'll understand.
