How to Get Evernight in Anime Girl RNG (Rarity & Biome)

The short answer

Evernight (March 7th) is listed on the community wiki at 1/1,000,000, Legendary tier, Galaxy biome only. It has been the single fastest-rising Anime Girl RNG search of the last three months, which is why every second video thumbnail is currently promising it.

Why the rarity number understates it

One in a million sounds like a weekend. It is not, because Evernight is biome-locked. The biome roll happens once every 10 minutes at a 40% chance, and Galaxy is one of several biomes that can come up. Your rolls only count towards Evernight during the minutes Galaxy is actually live — the rest of the time you are rolling against a table that does not contain it at all.

At base luck, one million odds needs roughly 693,000 rolls for a coin-flip chance. Every one of those rolls has to land inside a Galaxy window.

How to actually set it up

1. Bank your potions. Do not drink luck pots between biomes. Hold them.
2. Watch for the Galaxy biome. When it opens, that is the window.
3. One luck potion at a time. They do not stack — a second one replaces the first and you lose the difference.
4. Pair luck with haste. Haste potions cut the roll cooldown and are a separate system, so a Big Haste plus a luck pot is strictly better than luck alone inside a limited window.
5. Have a relic equipped. Relic luck is permanent and applies inside the window too.

What else is in the Galaxy biome

Galaxy carries around seven biome-locked auras in total, so a window is never wasted even if Evernight does not land — see the biome tables for the full set and their odds.
