Blighted map
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
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:
- Blighted maps are available in different tiers, with the highest being Tier 16.
- Higher tier maps have tougher monsters and can drop rarer, more valuable rewards.
- Blighted maps can be increased in quality using

- Can be crafted into Magic or Rare rarities, but it greatly increases the difficulty of combat, compared to Normal rarity maps.
- Map rarity affects the reward chests and the central drops.
- Map fragments that increase Item Quantity, such as
Sacrifice at DuskSacrifice at DuskItem Quantity: +5%5% increased Quantity of Items found in this AreaThe 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:
- Blighted maps can also be anointed, adding a variety of unique modifiers, including extra experience and significant boosts to rewards.
- Blighted maps cannot be used with scarabs, therefore it won't be consumed.
- Sextants have no effect on Blighted maps and won't be consumed when opening a Blighted Map.
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.
