An example of a Tier-16 blighted map with 20% quality

Blighted maps are alternate versions of existing maps that contain a more challenging Blight encounter than is normally found on maps. These maps have all the native monsters removed and are dedicated to the Blight encounter.

The map will always have an alternative map icon, as well as these implicit modifiers:

  • Natural inhabitants of this area have been removed
    Area is infested with Fungal Growths
    Map's Item Quantity Modifiers also affect Blight Chest count at 25% value
    Can be Anointed up to 3 times

Item acquisition

Blight icon chests from completing Blight encounters in maps have a chance to drop a Blighted version of a map. Blighted map drops are not affected by Cartography Scarabs.[1]

Mechanics

A player defends the Purification Pump from Blighted monsters that are trying to destroy it

Blighted maps only contain a small area with no enemies and a single Fungal Growth that spawns dozens of roots. Multiple waves of monsters will spawn from monster portals all across the map. Monsters move along a fixed route towards the Purification Pump. The player must defend the Purification Pump for 5 minutes, and then defeat all remaining monsters in order to complete the map and grant the rewards. Compared to regular Blight encounters in maps, in Blighted maps players get extended preparation time and Pump durability (health) is increased to 20 (up from 10).

Similar to regular maps:

  1. Blighted maps are available in different tiers, with the highest being Tier 16.
  2. Higher tier maps have tougher monsters and can drop rarer, more valuable rewards.
  3. Blighted maps can be increased in quality using Cartographer's ChiselCartographer's ChiselStack Size: 20Improves the quality of a mapRight click this item then left click a map to apply it. Has greater effect on lower-rarity maps. The maximum quality is 20%..
  4. Can be crafted into Magic or Rare rarities, but it greatly increases the difficulty of combat, compared to Normal rarity maps.
  5. Map rarity affects the reward chests and the central drops.
  6. Map fragments that increase Item Quantity, such as Sacrifice at DuskSacrifice at DuskStack Size: 10The Vaal shall never fear the setting of our sun.Can be used in a personal Map Device., can be used with Blighted maps.

Unlike regular maps:

  1. Blighted maps can also be anointed, adding a variety of unique modifiers, including extra experience and significant boosts to rewards.
  2. Blighted maps cannot be used with scarabs, therefore it won't be consumed.
  3. Sextants have no effect on Blighted maps and won't be consumed when opening a Blighted Map.
  4. Atlas passive skills don't apply to Blighted maps.

If you fail the blight encounter, it will not count as a map completion, however you can still collect all chests that have been already spawned.

Strategy

Blighted maps have a large amount of enemies and a large amount of resources for tower building. The same strategies that work on smaller Blights in maps will be useful, but more tower building and killing will be involved.

Anointments

Can be combined with other Oils at Cassia to Enchant Rings or Amulets, or to modify Blighted Maps.
s at Sister Cassia
For a list of anointments that can be applied to Blighted maps, see List of Blighted map anointments.

Sister Cassia can anoint your blighted map to increase the ease of combat, and/or to increase rewards. It is easy to self-sustain oils for these anointments because blighted maps provide a large number of oils upon successful completion. Generally, the higher the tier of the oil, the greater its effects.

    : Grant "25% reduced Cost of Building and Upgrading Towers" and "Towers deal 25% more Damage", and "12% reduced Monster Movement Speed" respectively. These oils reduce the difficulty of the encounter and may be useful for those who are struggling to successfully clear a blighted map. Generally, Sepia Oil will be be more useful early on in the encounter (due to low resources at the beginning and often an excess near the end) while Amber Oil will be more effective throughout the encounter. Due to its modifier's lower magnitudes, Clear Oil tends to be the weakest of them all.
  • Teal OilTeal OilStack Size: 10
    Oil Tier: 5

    : Grants "Blight Monsters spawn 30% faster, Encounter duration is 50 seconds shorter". Teal Oil reduces the time required to complete the encounter while making it more difficult. May be useful for those seeking "profit per hour" strategies trying to make the most of their time, if they are up to the greater challenge.

Not recommended for those running blighted maps for the rewards. Recommended to save for blight-ravaged maps, if used at all as blight-ravaged maps will grant more experience.
