Rain Engines

Viceroys can now take advantage of the Rain to power their buildings, but not without a cost! Blightrot will grow in Rain Engines as Viceroys use them, the more Rainwater that runs through an engine, the faster Icon UI Blightrot.png Blightrot Cysts will spawn. While Rainpunk is essential for any Viceroy playing on higher difficulties, it is a delicate balance between using Rainwater Engines and keeping the Blightrot at bay, as Blightrot likes to eat villagers. Blightrot scales with difficulty, so prepare to fight for your life at higher Prestige levels...

Types of Rainwater

There are 3 types of Rainwater: Each type will power a different type of building. DrizzleWaterCircle.png Drizzle Water powers buildings that produce food, ClearanceWaterCircle.png Clearance Water powers crafting and artistry buildings, and StormWaterCircle.png Storm Water powers heavy industrial buildings that produce fuels and metals.

Sourcing Rainwater

There are two ways of sourcing Rainwater:

Rainwater Collectors

A Rainwater Collector

Most players will start with building a Rain Collector that collects Rainwater during the season. Collection is based on seasons, so StormWaterCircle.png Storm Water can only be collected during the Storm Season, and so forth. Rain Collectors have tanks with a capacity of 50 units and collect 2 units every 16 seconds, and Advanced Rain Collectors, which you unlock in later levels, has double the capacity and speed.

Rainwater Geysers

A Geyser and Geyser Pump

A Geyser Pump is a building you can place on top of Rainwater Geysers to collect Rainwater, they have a base capacity of 50 units, upgradable to 100 units. Geysers produce 2 units of water every 6 seconds. They have two worker slots, upgradable to place two Automatons in worker slots for uninterrupted collection. It is important to note that a Rainwater Geyser will only produce Rainwater of the type that is the colour of the geyser, it does not change with seasons.

Chance of Geyser type per Glade type*1

Engine Usage

Install PanelEngine Controls

Viceroys can control how much water, and for what purpose, is used in a Building. To the left we can see a Viceroy clicked on the 3rd panel of a Building information box to open the engine controls of a Manufactory Manufactory. We can see:

  1. The 3rd panel with Rainpunk Information.
  2. The option and cost associated with installing Rainpunk.

On the right, we see:

  1. The 3rd panel with Rainpunk Information.
  2. The Controls. Click on this button with LMB to increase, and RMB to decrease usage.
  3. The Blightrot meter. Viceroys can hover on this panel so see how much Blightrot is being generated.

Engine Controls are as follows:

Left: (Uses 2 Units of Water per Level per Recipe / Minute )

  • 1 - Increase production speed by 50%.
  • 2 - Increase chance of double production yields by 25%.
  • 3 - Increase production speed by a further 50%.

Right: (Uses 1 Unit of Rainwater per Level per Worker / Minute)

It is important to note that as long as there are workers assigned and the secondary resolve-boosting engines are turned on, the Rainwater will be used and Blightrot will generate, even if no products are being produced. This can be useful sometimes to generate Blightrot Cysts. The rate of Rainwater usage depends on the amount of workers assigned, with more workers using more Rainwater.


See the Main page on Blightrot for further information.
