Slime Rancher 2 - Radiant Slime Sanctuary - Update 1.2.0 Notes

4/16/2026

The Radiant Slime Sanctuary update features new variants of slimes altered by the Prisma Core; Radiant Slimes, with a different color palette and radiant effect. These slime will be very rare and can appear anywhere their normal version might pop out.In addition, we are introducing the Caretaker and The Sanctuary; a special NPC and area specialized for caring for your slimes, particularly with helping your Radiant Slimes shed some of that Prisma energy (while still retaining their lovely radiant colors). This includes special ranch expansions and rooms which you can set to different themes and decorate, along with themed alcoves where your most cherished slime friends can hang out. We’re very excited to see how everyone customizes these!

What is more, these rooms can generate a new currency: Sprinkles! These can be used to unlock expansions in The Sanctuary, new themes, gadgets and decorations.

We know that’s already a lot of amazing stuff, but we didn’t stop there! We’ve also added:

  • A New Toy, the Resource Detector - it “actually” works as intended; indicating if a crafting resource is nearby. Batteries ARE included!

  • Gadget Bundles: Amazing deals in the Coo-Coo Corner on loads of decorations.

  • An Improved Storage Capacity upgrade for Silos; bringing each up to a 200 item limit per slot.

  • A Growth Amplifier upgrade for your gardens; granting extra growing space to get more of those home grown veggies and fruits your slimes love.

We hope everyone has a blast looking for Radiant Slimes and building out The Sanctuary. Stay wiggly ranchers!
