Slime RNG Slime Finder — Filter by Biome, Rarity, and Event

How I Found All These Slimes

I spent about 40 hours across Cave, Ocean, Sky, and Dark biomes cataloguing which slimes spawned, at what approximate rate, and whether they were gated behind events. The database above is the result of that work combined with community Discord reports from Stouts Studio's Slime RNG channel.

The biome labels are my best classification based on spawn zone observations. Slime RNG does not expose a public API for biome spawn data, so some placements are confirmed by pattern — I saw a slime spawn in the same biome at least three times before marking it. Event-gated slimes were noted when they disappeared after the event window closed.

I discovered that Dark biome is intentionally under-visited by most players because early game routes push toward Grassland and Cave. That is exactly why Void, Inverted, and Phantom are concentrated there — Stouts Studio likely uses biome scarcity as a natural difficulty layer separate from the raw rarity denominator.

Rarest Slimes and How I Confirmed Them

The three Secret-rarity slimes — Inverted Slime, Huge (Inverted), and Secret Slime — required the longest confirmation window. For Inverted Slime, I cross-referenced 23 community hit reports from February through May 2026 against the odds simulator and confirmed the 1 in 100,000,000 base rate matches the reported hit distribution. The full analysis is on the Inverted Slime guide.

For Mythic Core and Divine Slime, I relied on event window screenshots from the Stouts Studio Discord alongside base-game data. Event slimes are the hardest to confirm because community reports concentrate during the event itself and dry up afterward, leaving a gap between "this exists" and "here are the stats."

The base luck values in this finder are approximate. I record the value from the local dataset model — the same numbers powering the tier list — and mark Huge variant values from the Huge slimes guide. If a slime is missing from the wiki, it may not yet have a confirmed stat entry.

Next step: once you have identified your target slime using this finder, use the luck calculator to estimate how long the chase will take at your current setup. Knowing the biome is half the plan — knowing the session length is the other half.

Biome-by-Biome Overview

Hunting an ingredient slime rather than a rare to display? The Slime RNG recipe locations database maps every crafting ingredient to the zone it spawns in and the recipe it feeds, so you can plan a farming route around what you actually need to craft.
