I really wanted to give the Gloom Knight set a go since I had the pieces drop, and decided to put it on a Reaver.
Thanks to @Glimpse for the reference to the other Gloom Knight Build below. There are definitely a lot of changes you could make to suit your personal preferences here. The other build below is all in on Avalanche with Ascendant Bonuses, and if you were playing on SC you could remove some of the defensive layers I have, but as is this setup has done all content on HC Ascendant to date with no issues.
There’s definitely a higher level of capability to reach after Ascending all of the items… I’ll add an updated version after I go through that process. Since the FoA release I prefer to try and run an idea as far as I can before adding in Ascendant bonuses though, so this is done w/ just a straight build.
Bonus for the controller/simplified playthrough people, this build is super streamlined mechanically:
- Two buff shouts
- Two attack skills
- One debuff shout
No need to piano your way to success!
I play strictly HC, so I skew towards survivability and safety.
High OA/DA + 29% Dodge/29% Deflect + Multiple defensive layers gives a wide margin for errors for when GD likes to try and Merc you like it does.
(My Primary Setup Now) Alternate Devotions:
Grimtools: Reaver, Level 100 (GD 1.3.0.8) - Grim Dawn Build Calculator
Original more Defensive Setup:
Grimtools: Reaver, Level 100 (GD 1.3.0.8) - Grim Dawn Build Calculator
Grimtools Old
Grimtools Old: Reaver, Level 100 (GD 1.3.0.8) - Grim Dawn Build Calculator

Highlights so far:
SR 36 - Pushed to the next breakpoint now that I’ve done all other content
HC Ascendant Mog - OG - Face Tanked the whole encounter
HC Ascendant Ravager of Flesh - Approximately ~1 minute TTK (I didn’t time it though)
HC Ascendant The Dread - EZ fight. Dodge Red Balls, Face Tank the rest.
HC Ascendant Calla - Fiddly fight. Stick and move from obvious danger and he goes down.
HC Ascendant Crate - ~1 min fight EZPZ. Dive in, stack Onslaught/DoTs, kite back, rinse repeat.
HC Ascendant Mog - FoA - Stuns are super dicey, had to prioritize the rock tossers to keep the life leech going. Dodge big hits, play smart, he’s very dangerous.
HC Ascendant Nerf - Took a little longer than my Xbow Mystic, but smooth fight, just don’t get one shot!
HC Ascendant Uber Nerf - I do not recommend this fight, it’s just not fun dodging one shots the whole time. It is doable on this build though if you maintain good positioning in the arena.
HC Ascendant Fully Juiced Dread - EZPZ. Done w/ the Alternate Devotions Setup
Leveling was smooth sailing. There are a number of MIs that you can lean on to help along the way, like the dermapteran slicers, as well as the off-hand in the final build Rift Scourge Slicers. I didn’t care what armor I equipped along the way, the dps carries pretty well, I just made sure that it was relatively level appropriate and my resists were maxed out.
