Blightrot

Blightroot is a mechanic only present on difficulty Veteran or harder.

Every Recipe in production buildings has a Blightrot Footprint. This pollution accumulates and once it reaches 60 a Blightrot Cyst will form. The exact amount of accumulated Blightrot can be seen in the Blightrot tab in a given building’s UI panel.

Each Cyst lies dormant at first and brings some positive side effects with it. But during the Storm season, Blightrot Cysts wake up and inflict Corruption upon the Ancient Hearth (indicated by the progress bar above the Hearth and in the Hearth’s UI after selecting it). Once the Corruption bar fills completely, a number of villagers will die. The more Blightrot Cysts are active, the faster Corruption progresses.
