Papa Nurgle summons you forth to spread rot and decay!
The Build
With all permanent buffs including Consecration and Blood of Dreeg. DPS shown is with Righteous Fervor.
Obviously the Gun & Belt affixes are GDStashed, but you don’t need to do that as I show with the setup below. GT is still at 1.1.4.2 so the build is slightly different in-game.
The build will perform with a base item (affixes can be anything) Lunal’Valgoth’s Girdle and a Ugdenbog Venom Launcher of Alacrity. Any prefix is good, but get something with more Acid Damage.
Build Features
Upsides:
- Hybrid Acid/Vitality
- Great sustain
- DW Gunslinging fun!
- Build does not require specific affixes on MI items
- Not a Purifier, but a Putrifier!
Downsides:
- Run speed is not capped
- Decent WPS, but I wish Occulist had some too…
Build Overview
Here’s my idea of a Gunslinging Putrifier in Grim Dawn! 
This is my approach to a build that I have never seen posted online. I thought up this build in response to a recent thread requesting a DW Acid build. I thought about trying a Hybrid Acid/Vitality Sentinel with all the RR and it turned out to be fun, it looks great and plays great as well. Weapon Damage is pretty solid and all the procs make for the pretty good character.
It’s interesting to note that using the Dreeg’s Reproach Transmuter for Righteous Ferver converts any Physical/Fire damage you pass-through it, so Smite becomes Acid/Vitality. The Fire Damage from Void Rounds is changed as well. Pretty handy to know! This allows you to bypass using Path of the Three and instead you can pump Possession for all the juicy Damage Absorption and free Chaos Resistance.
Let me know what you think and if you have any questions or suggestions! Feedback is always welcome.
Equipment Choices
Try to get maximum Elemental to Vitality/Acid conversion and be sure to craft the Amulet, Ring & Pants for +% Physique.
Core Items:
- Set: Dark One’s Gift. [Great set all-around and can be farmed]
- Weapon 1: Ugdenbog Venom Launcher. [45% Elemental to Acid conversion to BoD, Crit Damage, +OA. Get a decent prefix and some Attack Speed]
- Weapon 2: Mythical Morguul’s Mortality. [Solid Attack Speed, excellent affixes and a nice added RR proc]
- Belt: Lunal’Valgoth’s Girdle. [~50% Elemental to Vitality conversion, affixes don’t matter]
- Amulet: Mythical Pesitlence of Dreeg. [+1 Oathkeeper/Occulist, ~25% Chaos to Acid conversion and a handy spreading curse skill]
Using the above items will get you 100% Elemental to Acid/Vitality & ~90% Chaos to Acid/Vitality conversion overall. With all the combined Hybrid RR going with Sentinel, you can deal out decent damage which will not be easily resisted.
Supporting Items:
- Ring 1: Mythical Deathlord’s Band. [Much needed Attack Speed, Pierce/Elemental Resitances]
- Ring 2: Mythical Widow’s Sting. [Flat Acid, +2 BoD and it’s craftable, so grab some +% Physique here!]
- Pants: Mythical Arcane Harmony Leggings. [Huge +DA/+Spirit are needed here]
- Boots: Mythical Boneshatter Treads. [Nice OA, and some Slow Resistance]
- Medal: Mythical Korvaak’s Brand. [Necessary to dual wield, but helps to have some extra damage and another WPS]
- Relic: Meditation. [+~200% Acid/Vitality Damage(!), +~5% Total Speed is great!]
- Movement Rune: Glyph of the Ravenous Wendigo. [Nice to leech a group as you run through them. Decent Damage.]
Devotions
Best Setup:
- Rumor > to Righteous Fervor
- Twin Fangs > to Bloody Pox
- Raise the Dead > to Smite (works great since it pierces 100% and hits with both hands!)
- Guardian’s Gaze > to Curse of Frailty
- Tainted Eruption > to Guardians of Empyrion (Scions of Dreeg)
- Abominable Might > to Plague of Rot
- Ghoulish Hunger > to any permanent buff
Gameplay
Keybinds:
- LMB: Point to Move
- RMB: Righteous Fervor
- Mouse Scroll Up/Down: Ascension
- Keyboard 1: Curse of Frailty
- Keyboard 2: Blood Pox
- Keyboard 3: Plague of Rot
- Keyboard 4: Wendigo Rush

Standard procedure:
- Movement rune in.
- Debuff using CoF, BP and Plague of Rot.
- Fire away with your guns blazing!
- Pop Ascension when it gets tough.
- If you get stunned or frozen, Guardian’s Gaze and Twin Fangs will keep you alive for a few seconds (cross your fingers!).
Build Performance
Shattered Realm:
The build is SR65+, maybe higher. I only checked to see if it’s possible.
Crucible:
I don’t play Crucible, so I’m not sure how it will perform. I am attaching the save file if anybody wants to take a stab at it. Since the build is SR65+ I imagine it can complete 170, but I’m not sure of the time and the buffs/banners required.
My Conclusions
This build is pretty fun and fits the bill for what a Gunslinging Acid/Vitality character should be in my eyes. It was a pleasure theorycrafting and making this build.
I will now backup my existing characters and start fresh with patch 1.1.5.0 leveling this exact character since I can farm all the items in the game pretty easily. I have not started fresh since I first started playing in May 2013 - it should be refreshing and fun for a change. (I hope! 
)
Wish me luck! 
Enjoy my take on a Gunslinging PUTRIFIER!
