Acid Ravenous Earth Oppressor



Welcome to a Complete Build & Leveling Guide for the Acid Ravenous Earth Oppressor. This build is one of the best starting builds in the game, can do all content (save a few super bosses) and easily farm Ultimate for set gear with self-found drops. It’s new player friendly and scales very well. If you’re looking for a fun, powerful and top tier starter build with a complete leveling guide, this is the place! Note the GrimTools link is at the bottom of the guide.

It’s been my experience this build is the strongest RE build out there, outperforming the traditional Vitality version of RE. While this build does start with traditional vitality damage, once the character equips a Leafmane Horn and converts to Acid (covered below under Gameplay), it melts everything with efficiency.

This build is hardcore viable and can easily reach 100!



This build is based on SFHobbit’s RE Acid Oppressor build. A shout out to SFH for his great video!

Update 1: Special thanks to Foxhull on Reddit for providing an updated and even stronger end-game version with the Pandemic Sword and Venomfire Amulet! New GrimTools link is at the bottom.



Before we begin, I recommend these mods to anyone playing Grim Dawn, especially new players. Note none of these mods cheat or change the core of the game – they just add quality of life:

GrimInternals (http://www.grimdawn.com/forums/showthread.php?t=53629
This is hands down the best mod currently out for Grim Dawn. Automatic component pickup and monster name/labeling with legendary drop Sound FX are just a few reasons why every Grim Dawn player should have this.

GD Item Assistant (www.grimdawn.com/forums/showthread.php?t=35240)
This mod allows the player to store an unlimited amount of items they find. This is fantastic because it supports “account building” with extending storage to be anything the player feels is important in the future or for another build.

Item Color Filter (http://www.grimdawn.com/forums/showt…407#post718407
A fantastic visual modifier to the game that shows item prefixes and suffixes in colors based on their damage/resist/skill type. Extremely popular and valuable.



Resistances are everything in Grim Dawn. If you die, it’s probably because your resists were low. Below is a list of recommended components that are commonly used throughout the leveling process:

Components List

  • 7: Wardstone | 7% Elemental, 15% Bleed Resistance | Amulet & Medal
  • 15: Silk Swatch | 18% Pierce & Bleed Resistance | Shoulder, Chest & Leg Armor
  • 15: Imbued Silver | 20% Chaos Resistance & 15% Bleeding Resistance | Mainhand/Offhand (Toggled Item Skill)
  • 15: Purified Salt | 20% Aether Resistance | Mainhand/Offhand (Toggled Item Skill)
  • 15: Antivenom Salve | 20% Poison & Acid | All Armor
  • 15: Unholy Inscription | 10% Vitality, 15% Bleeding | Hand Armor
  • 20: Runestone | 12% Aether & 12% Elemental Resist | Head Armor
  • 20: Soul Shard | 20% Vitality Resistance | Ring, Amulet, Medal
  • 20: Mark of the Traveler | 8% Movement Speed & 10% Slow Resistance | Boots
  • 24: Sanctified Bone | 18% Vitality, 12% Chaos | Chest & Head
  • 24: Aether Soul | 16% Aether Resistance | Amulet & Medal


Augments are the most important thing for end-game and require honored or revered reputation with a faction to access them. Rule of thumb: as soon as you hit Honored with any faction (which will begin to happen in Elite mode), immediately buy the Writ (for 88,000 iron) that doubles your faction gain. This will help you get to Revered much quicker, and give you access to the necessary augments to help your resists in Ultimate.

Augments List
The factions a player gets Honored and Revered with first are generally: Devil’s Crossing, Rovers, Homestead, Black Legion, Order/Kymon, and Coven of Ugdenbog. I’m listing some of the most popular defensive Augments below for reference, which can greatly help in surviving both Elite and especially Ultimate.

  • 40: Arkovian Rose Powder | 10% Elemental Res | Rings/Amulet | Rovers Honored
  • 40: Slith Venom | 15% Poison, Acid & Bleeding Res | Rings/Amulet | Devil’s Honored
  • 40: Gazer Eye | 10% Aether Res | Rings/Amulet | Devil’s Honored
  • 40: Corpsefiend Tentacle | 10% Vitality Res | Rings/Amulet | Devil’s Honored

Transmutation
This is a new and critically important feature introduced with Forgotten Gods that allows the player to convert set items to another item of the same setAnd it works with BLUE (non-legendary) set items! The quest to unlock Transmute is given by Kargon in the Conclave of the Three. The quest unlocks after you’ve progressed to the Oasis area. The Tome is found on Canen’s Corpse. It costs 120,000 iron per transmute, and uses 1 Eldrich Essence (which is quite rare, so make each transmute count!). Luckily, a player put together a guide on Farming Eldrich EssenceRemember, if you can craft the helmet of a set, you can transmute those helmets to other pieces. This means you can craft an entire set just from the helmet recipe!

Another technique is to convert a set item to another random set item. This costs 30,000 iron, scrap and crystals (which is a lot cheaper than converting to the same set). A good example of this technique is if you want the Mythical version of a set item (but you have none, and don’t have the recipe to craft the helm), you can take another mythical set item and convert it to a random set item with the possibility of getting a mythical of the set you’re looking for!



Final Level 100 Stat Distribution: 63 Physique, 3 Cunning, 40 Spirit.

The key items for this build are easily found and farmable as the player progresses through the story. The Bonespike drops from the Mages in Mountain Deeps. This lowers the recharge time and raises the duration of Ravenous Earth. The Leafmane Horn is what converts Vitality Damage to Acid Damage, and drops from the Leafmanes east of Coven’s Refuge in Ugdenbog. While the Leafmane Horn is usable at level 20, most players won’t get to Ugdenbog to farm it until 40 or so; but Ravenous Earth is so powerful it’ll perform just fine before the conversion to Acid. The Basilisk Crest also drops in the same area the Leafmane Horn does (east of Coven’s refuge) from the Basilisks. That is the most difficult one to find, so don’t spend too much time farming a good one until Ultimate; prior to that time, any prefix rolls will work just fine as long as you have the skill recharge adjuster for RE.

Pandemic (1H Sword) is the ultimate weapon goal for this build (L84), and replaces the bonespike, but it’s a very rare drop. One can also craft a Venomfire amulet at level 90 with a Cult of Dreeg blueprint.

This build is so powerful the play at early and mid-game is just rush, drop RE and rush. With bosses, use Judgment to debuff them. But when you get into Ultimate you’ll need to strategically use your Vire’s Might to proc scorpion, Judgment to debuff and pull large groups into your RE, and Ascension to buff your damage. Another key skill at end-game is Mark of Torment, which protects you from damage while it’s up – hit bosses with this as you rush back and forth through them with Vire’s Might while using Judgment and Ascension as it’s available. Rune of Displacement also provides a second jump if you need to get away from damage. If you are engaged in a tough fight, make sure you kite and use Vire’s might whenever it recharges to keep clear of big hits. I made it to 100 farming Ultimate like a boss with 0 deaths using this build with only self-found gear (I didn’t even have Dark One’s set).

This build can farm the Dark One’s set, but you have to make sure you are properly outfitted. This means all resistances maxed (and overcapped by some amount) and at least 16,000 health is recommended to be safe.



With the included leveling guide, GrimTools prior to level 94 isn’t really necessary, but I believe it’s always important to see where you’re going. Below is the end-game build for reference, showing the final gear, etc.
