Area is infested with Fungal Growths.
Regular Blight encounters in map have a chance to drop a Blighted version of a map. Blighted maps only contain a small area with no enemies and a single Fungal Growth that spawns dozens of roots. The player must defend the pump for 5 minutes, then defeat all remaining enemies. Players get extended prep time and pump durability increased to 20.
These maps can also be annointed, adding a variety of unique modifiers, including extra experience and significant boosts to rewards.
If you fail the blight encounter, it will not count as a map completion.
Blighted map cannot be used with map fragments. The map fragments will not be consumed so there will be no additional change in map quantity.
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.
