Blighted map

Quick Guide: This article has a quick guide that shows you how to use the Scout Tower strategy to complete a Blighted Map encounter.

Blight map preparation.png
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:

  • Area is infested with Fungal Growths
  • Natural inhabitants of this area have been removed

Regular Blight encounters in maps have a chance to drop a Blighted version of a map.

Mechanics

Blight map defence.png
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. The Atlas Awakening Level affects the difficulty of the monsters and bosses, with Awakening 8+ being the hardest.[1]
  4.

  5. Players can craft the map into Magic or Rare rarities, but it greatly increases the difficulty of combat.
  6. Running a Blighted map in Normal rarity provides for the easiest combat.
  7. Blighted map rarity affects the reward chests and the central drops.

Unlike regular maps:

  1. Blighted maps can also be annointed, adding a variety of unique modifiers, including extra experience and significant boosts to rewards.
  2. Players can annoint Blighted maps with Teal Oil inventory icon.pngTeal OilTeal OilStack Size: 10

    which provides a "Lucky" modifier to a fixed number of Blight reward chests
  3. Blighted maps cannot be used with map fragments such as scarabs. The map fragments will not be consumed even if players place them into the Map Device.
  4. Watchstone modifiers and sextants have no effect on Blighted maps

If you fail the blight encounter, it will not count as a map completion.

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.

The following is recommended:

  • A ranger or spellcaster build or any build that can do high amounts of area damage (melee builds using Cyclone inventory icon.pngCycloneCycloneAttack, AoE, Movement, Channelling, Physical, Melee

  • To run Magic blighted maps: At least 10 million damage per second
  • To run Rare blighted maps: At least 20 million damage per second
  • A method to increase damage against Rare and Unique mini bosses (such as Assassin's Mark for crit-builds, or Sigil of Power for lightning-builds)
  • Capped elemental resistances (fire, cold and lightning resistance at 75%)
  • At least 5,000 Effective hit points (Life pool)
  • At least 20% block or evade chance, or Mana before Life defenses
  • A strict loot filter that filters out most of the inexpensive loot

Sister Cassia can annoint your blighted map to increase the ease of combat, and/or to increase rewards. It is easy to self-sustain oils for these annointments because blighted maps provide a large number of oils upon successful completion.

Annointing tips are as follows:
