I'd like to preface this by saying that this build is not cheap, I don't know if it can be made cheaper and really don't want to try. Regardless the weapon alone will cost a pretty penny.

There's some room for improvement but I think I've gotten it to a point where it can do pretty much everything I want. I will link some videos when they finish uploading.

You can definitely build it for more dmg (replica dragon fang, voices for more abyss jewels, etc) but my preference has always been somewhere in the middle with comfy enough defences to do juiced maps.

• Vaal BV w/ 10sec duration
  • I generally have between 5-8 when I'm mapping and they auto target. This can go even higher if Atziri's Reign Procs
• Burst button (Unbound Avatar) feels really good to press (good audio feedback)
• 76% chance to evade, 100% spell supp w/ 56% prevented
• Conc ground+profane ground (Rational doctrine, Str+Int balanced

Pros:

• Defiance of Destiny w/ progenesis.
• Super smooth mapping (auto target, perma phasing, +108% movespeed)
• Perma freeze
• HoA
• Choice of movement skill (Whirling Blades pref)
• LGoH Recovery

Cons:

• not super giga zoom
• Bossing is doable but not built for that (cleared uber cortex and uberub elder since those were the frags I had lol)
• can feel weird to wait for a flask charge before you start the map, casting regular BV helps solves this since it does plenty of dmg.

Open to feedback!
