Blightrot

In the end, the Blight came.

= Overview =

Blightrot is sometimes described as a tax on Rainwater usage. Blightrot generates Blight Cysts and these cysts generate Hearth Corruption with continued Rainwater usage. The more water you use, the more Blight Cysts and Corruption generate. You can view your Hearth Corruption percentage on the bottom right of your screen. Clicking on the Icon will take you to the Hearth Corruption information page, where you can view how many Blightrot Cysts have generated as well as how much Blightrot generation you can spare until 3 random Villagers die.

From Veteran to Prestige 10 difficulty, the rate of Corruption generation is 60% Corruption a minute per Blightrot Cyst. It multiplies by 1.5x starting from Prestige 11.

Blightpost, Blightfighters and Purging Fire
On the left is a Blightpost, an essential Building used to produce Purging Fire which Blightfighters (Villagers assigned to the Blightpost) then use to burn off Blight Cysts during the Storm Season. Viceroys can also build a Hydrant to store extra Purging Fire near buildings that have grown a lot of Cysts. is made by using, ,  or.

A single Blightpost can handle a maximum of approximately 20-25 Blightrot Cysts per Storm Season on Veteran to Prestige 10 difficulty (this number goes down to around 15 at Prestige 11 and above). Beyond this point, multiple Blightposts will be needed.

The Hydrant
The exact number of cysts a Blightpost can handle varies depending on the movement speed and Global Work Speed of your Blight Fighters, and also by cyst location – the less time your Blight Fighters spend walking between the Blight Post and the cysts, the more cysts they will be able to burn. A well-placed Hydrant will greatly reduce this travel time, and may be essential if the distance between your Blightpost and the infested buildings is too great.

in a Blightpost have a +10% chance to double their Purging Fire production, and in a Blightpost get +5 to their Resolve.

Blightrot Cysts and Removal
Blightfighters (Villagers assigned to the Blightpost)) will burn Blightrot Cysts with produced in the Blightpost. This will remove Corruption.



On the left is a closed Blightrot Cyst, cysts will remain closed during Drizzle Season and Clearance Season, and they are invulnerable during this time. On the right is an open Blightrot Cyst, cysts will open during the Storm Season, and they are now vulnerable and able to be burned off with Purging Fire by Blightfighters.
