I usually try to keep these things separate from specific weapons, but in this case the Stygian LBG is truly the best accompaniment I know of for this set so yeah!
Stygian's Gunner gear is pretty good when you need Dragon damage, as long as you have a way to gem in Bonus Shot onto it. Starting with Dragon Atk +2 is really nice for enhancing those shots, 13 points of Evasion is weird but lets you get +2/3 really easily, synergising well with the Unscathed ability to keep your damage up. Load Up is more of a bonus for this set, but it does have uses - it lets you load all of your Dragon Shots in one salvo, maintaining efficiency. Boosting the salvos of Thunder and Pierce shots is good too. Finally, the negative skill on this set is a big one, but is removed with just one slot - Recovery Down makes your Health items only heal for 75% of their normal amount, which you really need to get rid of because it sucks so badly for a gunner!
This set isn't very flexible, but with a good Rapid Fire charm is still very powerful for using Dragon shots. Be sure to take lots of combines if you're going to use this set!
