When to push the button — a phase-by-phase guide for every stage of the game.
Rebirth resets your coins and slime collection, but permanently raises your luck floor. Think of it as a prestige system — each cycle gets faster.
Each rebirth adds +4% base luck (diminishing after R11). A player at R10 has a 40% luck advantage over a new player — before any buffs.
Some slimes only appear at high rebirth tiers. Voidcore requires R8 minimum. Solar Flare's best rate is at R12+. Rebirth is not optional for endgame.
Below 500K coins, the luck floor gain doesn't offset the coin loss. Farm to at least 500K before your first rebirth — even if it feels slow.
Every coin above the optimal rebirth threshold is wasted opportunity. Coins don't compound — luck floor does. Push the button when the calculator says so.
Rebirthing without recipe materials means starting from scratch. Stockpile Aether Glaze, Bio-Slurry, and Mythic Resin ingredients before you reset.
Enter your coins, rebirth count, and luck — get the optimal number instantly.
