Being the idiot that I am, I did not realize that Valinov had already done up a very viable doombolt deceiver build: http://www.grimdawn.com/forums/showthread.php?t=70777&highlight=doombolt+deleter
Ask not for whom the bell tolls, for it tolls for thee.
^EDIT: Just wanted to fashion dawn it up.

GT: https://www.grimtools.com/calc/62aw6ebZ <-- Edited GT link. Now with 70% WPS chance.

My sincere thanks to the usual crowd. :rolleyes:
Preface
Itās always baffled me a little as to why they arenāt more Chaos deceiver builds posted. With 2 skills granting flat damage and attack speed, 2 on demand heals which give OA and DA, the best chaos RR skill available in the game, and possession - I would have thought itād be a popular pick.
While I have no doubt that this build will do extremely well on a pyromancer, I feel that it would lack the defence needed to achieve the goal I had in mind: Clear 170 using no more than 3 buffs.
I had initially wanted to do it using just 2, but energy consumption becomes a huge issue past 150. (Strangely enough, I can consistently beat 150 unbuffed/unbannered with the current set up.)
At the risk of coming across as stupid, Iād like to mention that clear time and consistency increases TREMENDOUSLY with the vanguard banner as you can literally take nems out in about 6 seconds. Crits hit for about 650-700k per doombolt. We can literally shred 40-50% of a nemās life the moment one spawns.
Logic of the Build
It goes without saying that the harbinger set is key to the build.
Shadowflame mantle was chosen for an additional WPS, and divinesteel hauberk for more defense.
I opted to snag the bloodsworn sigil as I have way more fire RR than I do vit RR.
Shard of beronath was used to get an autoattack skill.
Grand total of -135% RR:
i. -20% from weapon
ii. -10% from ring
iii. -35% from devotions
iv. -25% from death sentence
v. -10% from relic
vi. 35 flat RR from set bonus
All said and done, DB consistently crits for ~300k, peaking at 400k or so under perfect conditions.
Autoattack show a sheet DPS of about 89k - while not mindboggling amazing, itās still a non trivial amount of damage especially when we consider the 70% WPS chance we have.
A thing to note about aeonās - Not only does it allow us to double DB, it also allows us to reset both our heals. This allows for some pretty damn good sustain.
In addition, āThe Harbingerā proc (100% dodge for 8 glorious seconds!) + Ghoul allows for some mad facetanking. This essentially gives you enough time to facetank a nemesis mob and take out one before needing to kite.
Do note that this is one of the few builds Iāve done up NOT equipped with GDstashed items. The affixes are far from BiS - again proving that smart gameplay (if I may so toot my own horn) and an understanding of mechanics are the 2 things really needed to clear 170.
Affixes to lookout for:
- Anything which fixes your resists
- OA, DA, Flat HP
- Energy
Devotion
- Purple crossroad
- 2 nodes into jackal
- Ghoul, viper, Eel, Sailorās guide, Watchtower
- Spec out of crossroad --> Get green crossroad
- Spider
- Solaelās witchblade, Scholarās light
- Spec out of spider --> Kraken
- Aeonās, Dying God, 5 nodes into revenant
To be honest, Iām uncertain if I should squeeze in fiend. (This can be done by giving up 4 nodes in revenant, scholarās light and the green crossroad for fiend and hawk).
Alternate, viable item options:
- As suggested by Korsar: Elite malmouth void pauldrons (https://www.grimtools.com/db/items/7648)
Ptir pointed out that the shoulders Iām using essentially result in a slight DPS loss per the crappy attack animation of the WPS. I opted to keep my shoulders, however, because:
i. My paranoid mind canāt handle not taking a free WPS
ii. In a run-'n-gun situation, when you only have time to get 3 or so shots in, being able to proc that WPS before kiting results in more damage.
