I gotta say, I'm really enjoying my combo of Wroggi gunner armor with the Wroggi Revolver bow. Stat attack and Rapid-type shot boosts, plus I get to run around Tanzia as a cowboy with a giant revolver on his back. It even makes those twirly-gun noises when drawn and holstered!
Wroggi Armor is what I'm striving for since I'm going to be using Dual Blades. Is it difficult to get all the pieces?
Not at all. There's a dual Wroggi quest at HR3 and it's extremely easy. You'll get all the parts you need after a few runs (will need a few Hercudromes as well, so farm those at the area while you're hunting them).
