Strange Controller: Forcing Biome Changes on Demand - Sol's RNG Wiki
A complete guide to the Strange Controller in Sol's RNG, covering its biome-forcing effect, crafting recipe, cooldowns, exclusive biome chances, and upgrade into the Biome Randomizer.
Overview
The Strange Controller is a consumable that forces a biome change according to the natural spawnrate in Sol's RNG. It is the on-demand way to hunt biome-locked auras and can even roll the rare GLITCHED biome, making it a cornerstone item for dedicated aura collectors chasing the hardest targets.
How to Get the Strange Controller
This walkthrough covers every material needed to craft the Strange Controller in Sol's RNG and exactly where to find them, so you can start forcing biomes as quickly as possible without wasting time hunting the wrong components across unrelated areas of the map.
Crafting Recipe
The Strange Controller is assembled at Jake's Workshop from a base pair of rare items plus one item representing each biome in Sol's RNG. Gather the components below before attempting to craft your first controller, since missing even a single piece will block the recipe and slow down your biome-forcing progression considerably.
| Component | Quantity | Notes |
|---|---|---|
| NULL? | 1 | Core rare component |
| Eternal Flame | 1 | Core rare component |
| Wind Essence | 1 | Windy biome item |
| Icicle | 1 | Snowy biome item |
| Rainy Bottle | 1 | Rainy biome item |
| Corruptane | 1 | Corrupt biome item |
| Piece of Star | 1 | Starfall biome item |
How the Cooldown Works
The Strange Controller is balanced by a dual cooldown system in Sol's RNG. Understanding both timers prevents wasted attempts and helps you plan farming sessions around Starfall or other target biomes, ensuring every single use is timed for maximum value rather than fired off the moment it becomes available again.
Check player cooldown
Each player can only use a Strange Controller once every 20 minutes, so stagger your attempts rather than spamming the item.
Respect server cooldown
A separate 20 minute server-wide cooldown also applies, limiting how often biome changes can be forced across everyone.
Plan around target biomes
Wait for both cooldowns to clear, then use the controller when your desired biome's natural spawnrate gives the best odds.
Exclusive Biomes It Can Spawn
Beyond standard biomes, the Strange Controller can roll two of the rarest biomes in Sol's RNG. These exclusive chances make it invaluable for aura hunters chasing biome-locked drops, and they explain why dedicated collectors hoard controllers specifically for high-value attempts at the most elusive biome-locked auras the game currently offers to players.
CYBERSPACE
A 1 in 5,000 chance when forcing a change, the digital-themed biome hosts several sought-after auras in Sol's RNG.
GLITCHED
A 1 in 30,000 chance, the ultra-rare glitch biome and the main reason collectors hoard Strange Controllers.
Natural Spawnrate
All other biomes follow their natural spawnrate, so common biomes like WINDY appear far more often than rare ones.
Biome Randomizer vs Strange Controller
A direct comparison pits the Biome Randomizer against the Strange Controller in Sol's RNG, revealing which item gives better odds for forcing rare biomes like the path to Limbo. Use the side-by-side results to decide which consumable deserves your crafting materials before your next serious aura hunting session.
In practice, the Randomizer wins when you need any rare biome evenly, while the Strange Controller shines for farming common biome items cheaply. Many collectors keep both on hand, using the controller for routine farming and saving the Randomizer for high-stakes attempts at the rarest biome-locked auras.
Biome Spawn Chances
When a Strange Controller forces a change in Sol's RNG, each biome appears according to its natural spawnrate. The table below lists the headline chances so you can weigh the odds before each use, helping you decide whether to save the cooldown for a better moment or spend it immediately on a quick farming attempt with reasonable odds.
| Biome | Chance | Tier |
|---|---|---|
| WINDY | 33.18% | Common |
| SNOWY | 27.65% | Common |
| CYBERSPACE | 1 in 5,000 | Rare |
| GLITCHED | 1 in 30,000 | Ultra rare |
Upgrading Into a Biome Randomizer
Four Strange Controllers can be combined into a Biome Randomizer in Sol's RNG, a stronger damaged-looking version with broader biome coverage. These points explain why the upgrade is worth the investment for endgame collectors who want flatter, more reliable odds across the entire biome roster instead of leaning on heavily weighted natural spawnrates.
- The Biome Randomizer requires 4 Strange Controllers, making it a significant late-game crafting investment.
- It offers a 1 in 8 chance to roll any biome, far better odds than the controller's natural spawnrate for rare picks.
- Visually it resembles a damaged version of the Biome Randomizer, reflecting its chaotic biome-forcing nature.
- Use it when hunting specific rare biomes, since the flat 1 in 8 chance ignores natural spawnrate weighting.
