I've been playing a Vanquisher for some time, using mostly dual-pistols and ranged attacks. I've been upgrading my Dexterity and picking up skills like Exploding shot and other things that seem like they'd increase my damage, but I've largely just been "winging it": picking things that sound cool or upgrading to items with more lines of attributes on them.
It's worked okay so far, but I'd like to aim for something in the rest of my play-through. I think I'm comfortable with my skill selections (Exploding shot and Ricochet, and spending almost all the rest in passives), but what should I be looking for—with respect to attributes—when trying to build a ranged vanquisher?
Should I be dumping all my attribute points into Dexterity, or is there a more balanced allocation?
Assuming I'm not trying to create a novelty build (like maxing out one stat—say, crit chance—at the sake of ignoring everything else that might be needed to get through the game without grinding my teeth—like say, survivability), what item attributes and runes should I be looking at?
Are there must-have attributes for Vanquishers, regardless of playstyle? Are there attributes that look good on paper, but don't really work as advertised?
