Gerrymon’s Hot Spring Expanded
In odyssey, hot spring spawns irregularly while giving a measly +2 mood buff for a 2-3 hours, so this mod aim to make hot springs an active recreation spot with extra buildables, increase the mood buff, and make hot spring have rejuvenation property for half a day. Perfect for hot spring lovers, not so much if you don’t plan on staying in a hot spring landmark!
Highly recommended to use with Perspective: Buildings.
Mood buffs:
– Swimming in open hot spring => +4
– Swimming in hot spring pool => +6, override above mood
Rejuvenated hediff:
– Blood filtration +20%
– Pain offset -25%

Encasing a hot spring pond with walls will turn the room into either public or private pool depend on the size of the room. They have different recreation type and have role priority over dining room and recreation.
You can’t put beds, laboratory equipments, nor production tables in the pools!
Sometimes people with chronic pain will come asking to join your colony in hope of using your hot springs to relieve their pain, it’s up to you to accept them or not.
Note: This should only triggered when you have any of the pool room on your map. Please report to me if it happened anywhere else.
Also, there’s a small chance the joiner do not have any pain on their person… if that happened, be a dear and add a scar using devmode. Or not, maybe they are lying about the pain and you have a perfectly healthy pawn joining you instead.


– Alpha Biome adds a healing spring variant, which count as valid terrain for any of the pool rooms. However it doesn’t gives the rejuvenation hediff (since it’s already have its own healing effect), nor can be spread with Hot Spring Spreader. Intended effect.
Q: How to use the water drill (hot spring spreader)?
A: You’ll need at least a single tile of hot spring terrain within the radius of the drill, and an open area for the water to spread into. They will not spread into player-made floors/structures, so you can utilize the fact to better control the shape of your pool. This also means the drill is totally useless if you don’t have any hot spring terrain to begin with.
Q: Why??
A: Balance reason, and to not make other landmarks moots. There’s other terraforming mods if you want to spawn hotsprings wherever.
Q: No Hot Spring Remover in case I over-enlarge my pool?
A: https://rimworldwiki.com/wiki/Moisture_pump
Q: Pawns not facing the inside of the pool when they sit on the pool bench
A: Yeah, there’s no way to easily recognize which side is the center of a pool, so they all sit facing south by default.
Q: Hot springs should clean my pawns when using it with Dubs Bad Hygiene!
A: People will beat your arse if you take bath in a public hot spring. Beside, have you seen actual hot spring water? They are nasty, if not full of algae and other natural matters, then with sulfur/other hard minerals. Not dirty per se, but definitely not hygienic enough by modern standards. That’s why onsens also have separate washrooms.
Q: Why does Alpha Biome’s healing spring spout out regular hot spring water when I spread it with the drill?
A: Just know it is intended behaviour.
Q: Will you add this and this and this?
A: If it still within the realm of xml coding, maybe…. I ran out of budget for making this mod.
