Level 83 Puncture Slayer^3.25

Notes

FOR (almost) FREE!?
  figure out your gems:
    remove deadly ailments + empower from boots
    remove vicious proj from helmet
    use vulnerability curse (drop faster attacks on blink arrow if not using mark of submission to make space for it)
    use enduring cry for endurance charge gen
    use blink arrow instead of dash (matter of taste)
    use automation + steelskin for more tank
  get uber lab ascendancy (masterful form)
  reconfig your skill tree a bit:
    remove expertise and ancestral knowledge (you don't need these until you have elegant hubris)
    remove jewel socket west of duelist (you have a free jewel socket, so this is dead weight that can be trimmed for now)
    remove bow mastery from deadly draw (you have resolute technique, accuracy doesn't matter)
    remove cannibalistic rite wheel
    remove life mastery from bloodless
    remove reservation mastery from champion of the cause
    remove life mastery from golem's blood
    add spirit void (leech to replace reduced cost, works out better i think)
    add leader of the pack wheel (frees mana)
    add tireless (more value than flat life mastery)
    add disciple of the slaughter (frenzy scaling)
    add savagery
    add fervour
  level up/quality your gems (can flip lvl 20 support + 1 gemcutter's prism -> lvl 1 support with 20% qual btw, if you didn't know)
  use pantheon (idk if you missed this in your original pob, but you should 100% be running brine king for freeze immune and anti-stunlock, at the very least. minor god is dealer's choice, i like yugul)

CHEAP
  6-link bow (bases are a couple of c, slam flat phys essence, craft inc phys, done. already like 15% dps increase on the bow alone, not to mention two additional links)
  less shit rares (idk how else to phrase this, your gear is pretty bad across the board. rares with life + 2/3 decent resists should be cheap at this point)
  darkray vectors (+1 frenzy, more movespeed)
  mark of submission (nice qol, will curse ALL enemies automatically and without reduced effect, skip if you need more stats on a ring)
  usurper's penance (good for dps, blocks spell supress evasion mastery. imo suppression is a "have it or don't" stat, so unless you can cap supression, i'd grab this instead)
  better flasks (don't need mana or quartz, get bleed on life flask, add jade and amethyst, roll better affixes on utility flasks)
  exarch/eater implicit your chest for endurance charge every x seconds, combine with duration charge mastery for perma-endurance charge uptime
  
LESS CHEAP
  anoint your ammy for +1 frenzy (frenetic notable is 2x silver + 1x blue, so 90ish chaos)
  6-link your chest (this will cost around 1 divine, or less if you're lucky ;P)

FUTURE
  ralakesh's impatience boot swap + olesya's delight (p expensive)
  better bow
  +1 frenzy haemophilia corrupt
  curse on hit vuln rare ring
  better rares again
  elegant hubris
  forbidden flesh/flame gratuitous violence
  gem upgrades
  etc etc
