Eldritch Altar Farming Guide


Eldritch Altars are not a league mechanic but are similar to one; they are easy to access and have atlas passive tree nodes. They are the most accessible high-profit end-game farming strategy and are available on every tier 14+ map you open for free after defeating an Eldritch pinnacle boss. Altars drop high-demand loot not found anywhere else in the game and pair well with additional farming strategies to increase its strength further. This Altar Farming guide will teach you how to maximize your loot, set up your strategy, and optimize your play with essential tips and tricks.



Altar farming is fast, efficient and offers a lot of valuable Currency from:

  • Eldritch Ichors
  • Eldritch Embers
  • Eldritch Invitations
  • Large Amounts of Atlas Currency
  • Scarabs
  • Assorted Divination Cards

These items are always in demand, maintain value and can sell quickly when priced appropriately and in large enough quantities.


Altar farming requires a character capable of Tier 14+ maps. We recommend having considerable durability and acceptable clear speed for maximum efficiency.

The only material requirement is a pool of Tier 14+ maps; however, you will also need one of the two Eldritch Beacons unlocked (Searing Exarch or Eater of Worlds) and the required Atlas Passives of whichever Eldritch Influence you prefer to farm.

Maps where the boss can be easily located and killed before any other monsters are best for maximizing earnings and lowering the difficulty of this strategy.


After spawning, Altars offer 2 of 3 possible reward types:

  • Boss reward (bad)
  • Minion reward (good)
  • Global reward (situationally good)

Minion rewards are the best option. After you kill the map boss, all Altars that spawn after its death will not spawn boss rewards, so subsequent Altars only offer minion and global rewards every time (increasing profits substantially).

The ideal maps for altar farming have the boss in a pre-determined location, preferably easily accessible from the starting portal of the map; luckily, many maps fulfill these criteria.

Here is an overview of how to run Altar maps:

  1. Locate the boss and avoid killing any monsters.
  2. Kill the boss.
  3. Clear the map.
  4. Always select minion reward when an Altar spawns.

Tips And Tricks

Boss Rushing

Kill the map boss as soon as possible; if needed, walk past monster packs. This rule is dependent on map layout and player knowledge. If you don't know where a boss is or how to prioritize finding the boss pick minion rewards when offered, skip global and boss rewards unless you're confident you can endure the extreme downsides.

Negate Altar Modifiers

Minion rewards are the most profitable and the safest to choose. They will only apply defensive and offensive buffs to Eldritch monsters. Boss modifiers apply to the map boss making them significantly more threatening. Global modifiers have reasonable rewards, but are incredibly dangerous so exercise extreme caution when choosing them.

Exarch Vs Eater

There are two influence types to choose from: The Eater of Worlds (Blue) and The Searing Exarch (Red). The Exarch influence is significantly safer to run using this strategy; most Exarch monsters are melee based, making them easy to dodge. Use the upgraded Abberath Pantheon when running Exarch. The Eater of Worlds is more challenging as it spawns many ranged monsters, but it is slightly more profitable due to better atlas passive modifiers.

Atlas Passive Tree

Atlas Passive Tips
  • Choose either Searing Exarch or Eater of Worlds, never both.
  • After acquiring 4 voidstones and 7+ favorite map slots, allocate the Singular Focus keystone.
  • League and map nodes on the 'base tree' are mandatory but travel nodes can be adjusted as needed.
  • Allocate the 'Enduring Focus' node when using Awakened Sextants.
  • Allocate the Eldritch Gaze and or Wrath of the Cosmos keystones for substantially more loot and challenge.
  • Use extra atlas passive points to specialize in an additional synergistic farming strategy.


Atlas State

Before farming Altars, have the following Atlas objectives completed:

  • 45 atlas passive points
  • The Omniscient Voidstone


  • The Grasping Voidstone

For seamless gameplay, infinite sustain of the best layout maps and maximum profit, you need:

  • The Grasping Voidstone
  • The Omniscient Voidstone
  • The Ceremonial Voidstone
  • The Decayed Voidstone
  • 46 atlas passive points
  • 10+ Favourite Map Slots

Map Choice

Layouts where the boss is easily accessible and deterministically spawns are best the ones below have extra merit or are particularly well suited to the mechanic. When Favouriting maps or moving toward infinitely sustaining one map, these should be your top picks:

  • City Square and Mesa are the easiest maps to access the boss as fast as possible. The boss always spawns at the center of the map close to the starting portal. Both maps have low monster counts so map sustain can be challenging.
  • Dunes has its boss situated in a small outcropping branching off the side of the map. Follow the border of the map and dodge packs of monsters to get there quickly. Dunes has a good amount of monsters making sustain easy and drops the Acclimatisation Divination Card for higher profits.
  • Shore has the boss located on the coast, found by traversing down the cliffs located near the start of the map. After reaching the shoreline, continue up until you find a ship wreckage and click the pirate booty to spawn the boss. Shore has a high monster count for map sustain and also drops The Destination Divination Card.

Rolling Maps

Rolling your maps correctly is essential for increasing profit and sustaining maps in the end game.

Have at least 10 maps suitable for Altars at Tier 14+ before beginning to farm. If you don't have enough, they can be purchased off other players or farmed up yourself.

For this strategy roll all of your maps using the following materials that you intend to run Altars on.

  1. Clean Your Maps - Ensure all of your maps are identified and then use an Orb of Scouring to make them all normal rarity, since achieving 20% quality on white maps requires significantly less Cartographer's Chisels.
  2. Chiselling - Use Cartographer's Chisels on all of your maps until each one is 20% quality.
  3. Alchemy Orbs - Use Orb of Alchemys on every map you have at 20% quality. Re-roll maps your character cannot run using Orb of Scouring and Orb of Alchemy.
  4. Vaal Orbs - Use Vaal Orbs on all of your appropriately rolled maps. Some maps may transform or receive new modifiers, so weed out any maps with modifiers your build cannot run or that are no longer on a favourable layout for Altars. On average using Vaal Orbs on high tiers maps is always worth it.

Selling Your Loot

Here are the drops you can expect to acquire with this strategy, as well as some advice on how to sell them effectively and quickly. Follow our Bulk Selling guide to learn more.

Eldritch Currency

You will receive a significant amount of Eldritch Ichors and Eldritch Embers from altars with the Ichor or Ember minion reward type. Ichors and Embers are a massive part of your earnings and are used by most builds when crafting end game best in slot gear. As such, they should be sold using bulk pricing methods listing at competitive prices. because of massive demand players often opt to buy large quantities at once making sales incredibly efficient.

Eldritch re-roll currencies can drop from influenced monsters but are incredibly rare. These currencies (such as Eldritch Chaos Orbs, Eldritch Exalted Orbs and Eldritch Orbs of Annulment) should be priced individually and ideally only sold when you have 2-3 at a time.

Eldritch Invitations

Eldritch invitations are a guaranteed drop off the map boss, every 14 influence maps you complete of a certain influence (e.g. every 14 eater of worlds influenced maps). There are two different invitations for each influence type (major and minor). Your first 14 maps will drop a minor (e.g. Polaric Invitation) and your next 14 will drop a major (e.g Incandescent Invitation) alternating back and forth.

Major boss invitations are worth a lot of Currency. The bosses drop powerful end game Uniques such as the chase items Crystallised Omniscience and Ashes of the Stars. However, minor boss invitations are still worth selling as their bosses drop Eldritch Crafting Currency frequently.

Invitations can be sold fast individually, but you should wait until you complete your farming session to list them all using bulk selling methods to save time trading.

Atlas Currency

Altars drop a lot of atlas currencies after selecting the corresponding minion reward. Atlas currencies include Cartographer's Chisels, Awakened Sextants, Orbs of Unmaking, Harbinger's Orbs, Orbs of Horizons and more.

All mapping strategies rely on atlas currencies which makes selling them incredibly profitable, They should be sold using bulk pricing methods at competitive prices. Consider keeping some or all of the atlas currencies you drop for yourself and future mapping and strategies.


Scarabs drop frequently when selecting the Scarab minion reward option and follow the standard drop rules with the majority being rusted quality, some polished and only a few gilded. There are many different types and rarities of Scarab, so earnings can vary based on luck and timing.

Selling Scarabs is not easy due to their variety; listing each of them is time consuming and trading them is tedious. The fastest way to sell them is offloading them to players that purchase entire scarab tabs at once on community trading Discord servers.

Alternatively, you can list scarab types individually. Price check each type and list them using bulk selling methods. This should only be done at the end of big farming sessions to save time.

Miscellaneous Drops

Altars drop a variety of miscellaneous items worth selling,  such as Divination Cards and Maps. Each of these have frequently-encountered minion altar reward options. Maps that drop from altars will likely be your favorited ones, resulting in greatly increased map sustain, if you have more than you need sell them. 

Divination Card altars award a random assortment of Divination Cards. They should be priced and sold individually; turn in any full sets you collect.


Eldritch Keystones

Altars have two keystones on the atlas passive tree: Wrath of the Cosmos and Eldritch Gaze. Both increase the loot of altars but add enormous difficulty. Only take these keystones if you understand the downsides they impose on your maps and  you are prepared to die frequently (or have a character that can endure the punishment).

Invitation Speed Farming

Invitations add incentive for clearing maps quickly – the more maps you clear per session, the more invitations you farm to sell. Map layouts you can clear quickly while boss rushing become priority due to the incredibly high price of eldritch invitations. Adding the price of a minor and major invitation together and dividing it by 28 will tell you how much you earn per map from this alone!

Strategy Synergies

All Leagues

The low atlas passive requirements, on top of the flexibility of Eldritch Altar farming, means it should be used along side another farming strategy. Almost all other farming strategies synergise well with Altar farming. You can find some examples here:

You may need to modify the strategy when boss rushing is not an option, prioritizing your safety over loot when minion rewards are not available. Even without clicking a single Altar, Eldritch influence is always worth using for free monster packs and Eldritch invitations.

Alchemy And Go

Alchemy and Go combines multiple low maintenance league mechanics that reward speed and have low character and investment requirements. It is a perfect accompaniment for altar farming and a great place to spend your remaining Atlas Passive Points.

Both strategies also favor similar layouts, with an emphasis on small deterministic layouts that can be quickly run. The combination of Alchemy and Go and Altar farming is one of the most competitive strategies for end game Currency farming  currently.
