Sol's RNG Biomes and Breakthrough Guide
Biomes are timed game states that can change which Auras are realistic chase targets. Use biome odds as planning context, then check the calculator or rolling simulator before spending potions or long roll sessions.
Quick answer
Biomes are timed game states that can change which Auras are realistic chase targets. Use biome odds as planning context, then check the calculator or rolling simulator before spending potions or long roll sessions.
What biomes change
A biome can make specific Auras more relevant by giving them a native chance in that environment. The base rarity still matters, but the native chance is the better number to use when the Aura is tied to the active biome.
- Use base rarity for normal rolling context.
- Use native chance when the Aura has a matching biome entry.
- Treat missing biome data as unknown rather than assuming a multiplier.
How to plan around biome chance
Start with the target Aura, check whether it has a native biome, then compare the native chance against your total luck and roll speed. This keeps the decision grounded in probability rather than only rarity labels.
Breakthrough context
Breakthrough-style rarity can change the practical chase path for some Auras. Until every breakthrough case is structured, use the listed native chance and notes as context, and avoid treating the simulator as exact server emulation.
FAQ
What is a biome in Sol's RNG?
A biome is a temporary environment state that can affect which Auras are worth chasing and may expose native Aura chances for that state.
Should I use base rarity or native chance?
Use native chance when the Aura has a matching biome. Use base rarity when no matching biome chance is available.
Can I simulate biome rolls?
Yes. The rolling simulator applies native chance when the selected biome matches the Aura data available to the site.
