Sol's RNG Wiki

Runes are consumables that let eligible auras roll at their native rarity without requiring the matching biome. Weather and special-biome runes focus the chase, Rune of Eclipse ignores the daytime or nighttime requirement, and Rune of Everything covers supported biome pools for a shorter window. Their obtainment routes and exclusions differ, so the target pool and exception notes matter before you spend one.

Lanterns are pocket gear crafted at Stella's Cauldron to target a biome. Each lantern doubles the spawn chance of its linked biome, including WINDY, SNOWY, HELL, HEAVEN, CORRUPTION, and NULL. You choose one for the pocket slot, so the right pick depends on the biome and materials you are hunting.

Auras are what every roll in Sol's RNG produces: cosmetic effects drawn from a fixed rarity table that runs from common Basic drops to one-in-hundreds-of-millions chases. Base odds never change, but potions, gears, and active biomes stack luck or swap in far better native odds, and some auras are craft-only or locked to The Limbo. Knowing which aura sits at which chance, and in which biome, is the difference between a plan and a prayer.

Gears are equippable hand items that passively boost your rolls: right-hand gloves and devices add flat luck or roll speed, while left-hand gear reshapes the Bonus Roll system with shorter cooldowns and multipliers. Nearly all of them are crafted at Jake's Workshop from specific auras and materials, so duplicate auras become crafting stock. Since you wear one per hand, every choice is a slot-by-slot comparison.

Potions are timed boosts you drink before rolling: each one adds luck or roll speed for a set duration, from one-minute map pickups to four-hour crafted brews and one-roll spikes worth hundreds of thousands of luck. Small ones spawn free around the map while the strong tiers come out of Jake's Workshop recipes. Timing a big potion to overlap a biome window is the core trick of aura hunting.

Biomes are timed map states that reroll every second and change which auras are cheap: while Rainy, Hell, Starfall, or another biome runs, its native auras drop at several times their normal odds. Most cycle naturally on per-second chances, while Cyberspace only opens through biome items and Singularity hijacks one in a hundred Starfall spawns. Aura hunting is really biome hunting with extra steps.
