Rain Fortress

6/21: 1.5 IS HERE!!! Watcher creatures, lizard resprite, new plants and more!

PLEASE ENABLE SEASONAL AUTOSAVES WHILE PLAYING WITH THIS MOD! There is a very rare crash upon caravan arrival that I haven't been able to squash yet. If anyone is able to find the cause of this, I will implement a creature or creature subtype into this mod (or secondary mod) of your choosing - this can be a fanmade critter, a hybrid, rare scug feature or coloration from your oc... I'm open to suggestions!

Just your average rain world fanmod~

This mod aims to be as close to rain world lore as possible, though I will be deviating somewhat in order to attempt to provide a more balanced and interesting play experience, and may sneak in some fanon tidbits for flavor. After this mod is completed, I plan to create a secondary mod introducing fan creatures and other additional content!

(As a forewarning, most of my testing focus is currently on fortress mode. I'm working in compatability with adventure mode where I can, but things may behave unexpectedly!)

Check out the In-Depth Bestiary for more info on the specific creatures in this mod.

- 15 different fur colors, 8 ear shapes, 3 rare features
- Slightly smaller than dwarves
- Civ only has access to spears, crossbows, axes, and picks

- Civ spawns in temperate wetlands and favors any wetlands for expansion, with grasslands/savanna/shrublands/river close behind

- Train Lizard (megabeast)
- More misc creatures
- RW creature statues
- Slugcat sprite rework (will include portraits lol)
- Custom toys
- Scavenger civ that can temporarily paint themselves and other creatures
- More plants (gooieducks, dandelion peach, glow weed, pole plants)
- Creatures/plants from The Watcher DLC
- Additional things if I figure out I can do them in the first place haha

- Misc fan creatures (list is very long and meaningless without context, will be taking suggestions closer to implementation)
- NPC ancient civ that specializes in selling exclusive hybrids and purposed organisms
- NPC iterator civ that can give marks of communication to creatures
- Opt-in genetic modifications mechanic (teachable secret for ancients and iterators)
- Multiple distinctly purposed scug races with unique graphics and abilities that your slugcats can be modified into
- Voidworm and general void-related implementations (void scarring, void spawn, voidworm megabeasts?)

I could very well just have all the content in one mod. Howeeeever-- splitting the content into two mods allows me a bit more freedom in what I implement. The main mod (this one) sticks more strictly to what's in the main rain world game, and adds just enough content to give you that bit of "vanilla" rain world flavor you might be wanting.

The secondary mod is where I'm putting the content that may be more "out there" in comparison! It's all still very much rain world flavored, but I'm free to do things that alter the game experience more drastically, or veer more into headcanon or fanon territory. I understand that some people may just want to mess around and tame lizards without having to think about the iterator civ next door that wants to experiment on your scugs, or having ancients try to trade you a whole entire miros yeek, and that's totally understandable.

Want updates on mod progress as it happens, announcements when a new patch drops, sneak peeks, an organised spot for suggestions/contributions, and more? Join the discord!

It's relatively quiet, but steam discussions are horribly inconvenient and I wanted an easy way to notify people when something important happens, run polls, etc. I'll be giving progress updates on any new mods I make in there, too!
