Premium targets top three rarities
Premium Lucky Blocks are re-normalized to Legendary → Beyond (top three rarities). The Standard Lucky Block covers the full ladder.
Use the Index ETA tool
Forecast rolls with the Index ETA tool. Default priors use a 0.50 geometric decay (each tier is half as likely as the one below it) — editable if the wiki publishes official rates.
Beyond at default priors
Standard Beyond: ≈1,000 rolls per animal. Premium-only Beyond: ≈14 rolls per animal. Plan your Premium share (φ) before committing Robux.
Robux cost projection is eye-watering
Premium-only Index completion at default priors costs ≈113,000 Robux. Use the Standard-block long-tail for the common half of the Index.
