Rainpunk

A Stormwater Geyser

Overview

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 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 different types of buildings. Drizzle Water powers buildings that produce food, Clearance Water powers crafting and artistry buildings, and Storm Water powers heavy industrial buildings producing fuels and metals.

Sourcing Rainwater

There are two ways of sourcing Rainwater:

• Collecting Rainwater from the sky via buildings such as the Rainwater Collector and Advanced Rainwater Collector.
• Building Geyser Pumps on top of Water Geysers.

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 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

Geyser Pumps are buildings you can place on top of Rainwater Geysers to collect Rainwater, they have a base capacity of 50 units, upgradable to 200 units. Geysers produce 2 units of water every 6 seconds. They have two worker slots, upgradable to place 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.

Engine Usage

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.

Here you can select which perks you would like to enjoy when using Rainwater, as well as how much Rainwater you would like to use. On the bottom left of the information box, we can see a Blightrot meter. This meter shows you how much Blightrot your engines are spawning.

Engine Controls are as follows:

Left:

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

Right:

• 1 - Workers gain 5 Resolve.
• 2 - Workers gain a further 5 Resolve

It is important to note that as long as there are workers assigned and the engines are turned on, the Rainwater will be used and Blightrot will generate, even if no products are being produced.

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

A Blightpost

A Blightfighter burning a Blight Cyst

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

A 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.

Blightrot Cysts and Removal

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

A closed Blightrot Cyst

An open Blightrot Cyst

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.
