Blightrot
In the end, the Blight came.
Blightrot
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. 
Purging Fire is made by using 
Coal , 
Sea Marrow, 
Oil or 
Wood.
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.
Harpies in a Blightpost have a +10% chance to double their Purging Fire production, and 
Lizards in a Blightpost get +5 to their Resolve.
