Not bad. Sure, it's a bit simple, but since when has GS been an exercise in complexity? Hurk's about one thing: getting in the boss's grill and staying there while beating the crap out of it. While GS is a relentless onslaught that doesn't have to worry about Stamina or Health, Teide involves a bit more finesse and micromanagement, which differentiates it enough from GS to be a change of pace. I'm interested in what the best usage of Doubleshot will be and when to use Impact Sure Shot for optimal results. Since it only has a 1 min CD, it's pretty flexible. Probably just, "whenever the boss is far enough away and only while you have 3 Wounds on it" :P
The only downside is that I'm gonna need a new outfit to fit with the aesthetic of this weapon. Or maybe just new pants.
