What this mod does

Make use of those steam geysers dotting the map for more than mere electric power! With a great deal of clever excavation deep underground, the groundwater that fuels a steam geyser can be brought gushing to the surface. A large amount of stone blocks are used to stabilize the shifted earth and form a clean, abiotic vessel in the ground, pooling the pure, steaming water into a luxurious hot spring.

This gorgeous all-natural bath will be automatically used by pawns as a potent source of meditative joy, and is capable of hosting up to six pawns at once.

It is of special interest to sick and/or injured colonists; the soothing heat and therapeutic trace minerals within the hot spring's waters greatly accelerate recovery from injury and illness. Colonists capable of movement can maximize their uptime on the hot spring's positive hediff by being manually directed to use it once per day, hastening their return to health as soon as possible.

Hard numbers

Too long for Steam.

How will this mod affect my gameplay?

This mod allows pre-electricity colonies to benefit from steam geysers with a non-trivial investment of 500 stony material and several days' worth of construction labor. It encourages building facilities directly around it, as it is useful for both recreation (pawns using it in an impressive room will gain an impressive rec room positive mood) and for injury/illness recovery (recovering pawns should be kept near it to minimize walking time to and from it).

Colonies that have electricity must 'sacrifice' a potential geothermal generator, as steam geysers are a limited resource. You will need to find alternative sources of power.

The Blood filtration buff is rather modest, equivalent to only 16% of a kidney. It will rarely be the most important factor in immunity gain.

The Natural healing factor increase is very strong, as the only other (non-mod) source of increase is an implant locked behind a techprint. If this bothers you, you can easily reduce the hediff's strength or remove the effect altogether by editing the HediffDefs in the .xml.

Tested With

While this mod's code was based on the hot spring from ssulunge's Kijin Race 2.0 mod, everything in the backend was renamed and recategorized properly to ensure that the mods should not conflict on a compatibility level.

Mod order seems to be irrelevant as long as it comes after Core/Royalty.

Graphics

Workshop page art can be found here. It was drawn by 隂宅.

The original art for the hot spring was drawn by Lumi MercuryDoll. It was further modified, enhanced, and given a stuff-mask by the talented Vincent_Wolfgang.

About and Acknowledgments

Please let me know in the comments section if you encounter any problems with this mod. I have little experience with game modding, so any comments, feedback, and/or coding/implementation pointers are greatly appreciated.

If you would like to show your support, please consider donating to my Ko-fi page. Every penny I receive means I can spend less time on other work and more time on realizing mod ideas such as this one.

If you're a fellow Rimworld modder, please do your part for inter-mod soft compatibility by making your mod's buildings Stuffable, as opposed to requiring exactly Steel or WoodLogs.

A very big thanks to:

ssulunge for creating the Kijin Race mod in the first place. His original C# code forms the basis of this mod's code; without it, I never would have even considered undertaking this project.

"Wiri" (from the Rimworld discord) for taking me by the hand and teaching me about .dll decompilers, Visual Studio, and Rimworld in C# code far above and beyond what a static tutorial ever could.

dninemfive for having written the Plague Gun tutorial in the first place, encouraging me to step into the world of C# properly, and for continuing to assist me with Rimworld code screwups beyond it.

Vincent_Wolfgang for taking the fate of my ugly texture into his own two hands. He improved the original bootleg texture's linework, greyscaled the rocks to work with a stuff-mask, and made said stuff-mask almost entirely on his own initiative.
