Warning: This guide assumes you have learned the basics of Blight from our mechanics guide. Read that first before continuing!
Blight is one of the most accessible end game farming strategies for many builds and does not require an exceptionally strong or fast character. It features two major money makers (Oils and Blighted Maps) which sell easily and retain most of their value throughout a challenge league. In this Blight Farming guide you will learn how to maximize your loot, set the strategy up and optimize your play with essential tips and tricks.
While Blight is not the most profitable mechanic, it is incredibly consistent and offers valuable Currency from:
- Tier 14-16 Blighted Maps
- High Grade Oils (Opalescent Oil - Golden Oil)
- Oil Extractors
- Miscellaneous League Drops
Blight's small loot table means your drops can be sold quickly and in bulk all at once. Blighted maps and oils are always in demand but you must price them correctly and competitively to ensure they sell. Refer to our bulk selling guide here.
Blight has not have an extreme character requirement as Blight towers contribute a substantial amount of crowd control and damage; However a character with high single target damage to manage unique bosses and some form of monster explosions makes things a lot easier.
Blight also requires the use of Scarabs, the Atlas passive tree and an end game Atlas in order to sustain it and maintain profitability. Having access to a pool of Tier 16 maps is preferred, but the strategy works as soon as you can access good Map layouts for Blight at Tier 14+, usually requiring 2 Voidstones.
Blight should always be used on enclosed map layouts as it greatly increases the quality and quantity of loot you receive.
Here’s how to run Blight maps:
- Clear the map normally until you encounter the Blight.
- Open a Portal Scroll to open a portal to town in case you die.
- Click the Fast Forward Button to start the Fight encounter faster.
- Keep the pump safe at all times.
- Build towers to win (see the tower strategy below).
- Collect your loot and finish the map if you haven’t already.
Tips And Tricks
Blight Reward Tendils
When a Blight spawns its tendrils one tendril will always contain ONLY Blighted reward chests, which drop all of the most valuable items we are after. Blights in enclosed layouts spawn less tendrils, but still offer the same amount of reward chests. The result is more guaranteed Blighted reward chests concentrated on the tendril with guaranteed Blight rewards. In extreme cases you can have all reward chests be Blighted rewards on one tendril!
All resources you accumulate should be spent on minion towers to distract enemies and slow down their advance on the purification pump. Once you reach a decision point for upgrading your towers, always turn them into Sentinel towers (Flying Robot Swarms) as they provide fantastic single target damage that can help deal with unique blight bosses.
Oil Extractors are special drops that come from blight reward chests. They can be sold, but are more importantly used on specific anointments on jewelry to extract high value oils (Golden Oil, Silver Oil and Opalescent Oil). Suitable jewelry for extraction can be purchased off the trade site, or collected from blights themselves.
Atlas Passive Tree
Atlas Passive Tips
- Use extra Atlas Passive Points to specialize in an additional synergistic farming strategy.
- League and map nodes on the 'base tree' are mandatory but travel nodes can be adjusted as needed.
- When using Awakened Sextants allocate the 'Enduring Focus' node.
Before farming Blight, have the following Atlas objectives completed:
- The Grasping Voidstone
- The Omniscient Voidstone
- 70 Atlas passive points
- 7 Favourite Map Slots
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
- 70 Atlas passive points
- 10+ Favourite Map Slots
Closed layout maps are preferred since they give additional Blighted rewards. Any closed and narrow layout map can be used for Blight farming, but the ones below have extra merit or are particularly well suited for it. When favoring maps or moving toward infinitely sustaining one map, these should be your top picks:
- Core is considered the best Blight layout map in the game. It is so narrow and finicky that you always get 1-3 Blight tendrils. The map doesn't have the best natural mob count, but is reasonable for map sustain due to the 3 additional mini bosses you can kill every run.
- Toxic Sewer/Waste Pool are two of the best map layouts in Path of Exile and are a reasonably strong pick for Blight. They are not as strong as Core or Flooded mine for tendrils, but are much faster and more fun to run.
- Flooded Mine is widely considered one of the worst layouts in Path of Exile due to how cramped and winding it is to run, which is exactly what makes it so good for Blight and getting the lowest amount of tendrils possible. In leagues where Core is not available, Flooded Mine is a reasonable choice for maximizing Blights if you can stand the layout.
Rolling your maps correctly is essential for increasing your profit and sustaining maps in the end game.
Have at least 10 maps suitable for Blight 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 Blight on.
- 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.
- Chiseling - Use Cartographer's Chisels on all of your maps until each one is 20% quality.
- 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.
- 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 Blight. On average using Vaal Orbs on high tiers maps is always worth it.
When farming Blight, at minimum use the following Scarabs and fragments:
- Rusted Blight Scarab
- Sacrifice at Dawn
- Sacrifice at Noon
For larger profits use a higher investment setup with:
- Gilded Blight Scarab
- Rusted Cartography Scarab
- Rusted Elder Scarab
Blight farming does not require any specific sextant modifiers, but as with all strategies, sextants increase your profit for next to no cost in the long run.
Always use Awakened Sextants to roll additional monster packs on all your available void stones to ensure you sustain your maps. Use Surveyor's Compass on valuable sextants you don't want to use so they can be sold.
Kirac modifiers are a set of league modifiers that can be accessed via the map device for a Chaos Orb fee per map. Even when Blight is a Kirac modifier it is never worth using since you cannot spawn multiple Blights in one map. Blight Scarabs are always far more cost-effective and offer additional benefits over Kirac modifiers.
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.
Oils are such a common drop while running Blight that it can be tedious to loot all the lower tier ones from every chest you open. Low tier oils can be hidden at your discretion to avoid dealing with them every map you run. Oils that are completely safe to hide are:
- Clear Oil
- Sepia Oil
- Amber Oil
Using Your Oil Extractors
As mentioned above, Oil Extractors can be used by players to acquire expensive oils from anointed jewelry. Due to Blight Atlas passives anointed jewelry drops consistently from Blight encounters.
If you are able to identify which anoints on jewelry are worthy of using extractors on, you can accumulate more high tier oils from your farming sessions. Unfortunately though, learning which pieces of jewelry to use extractors on is very challenging.
Alchemy and Go
Alchemy and Go is a strategy that combines multiple low maintenance, easy to sell league mechanics that reward speed with little to no character or map requirements. This makes it a perfect companion for Blight farming and a great place to spend your remaining Atlas passive points.
This guide explains:
- The low character and currency requirements of Blight.
- The consistency of the strategies loot drops.
- How to run and make currency from the strategy.
- A suitable Atlas Passive Tree Skeleton to use.
- How to sell the loot that you've earned converting it into liquid currency.
