Click the wing icon near your cash display, walk your character onto the upgrade you want to lock, and confirm. Plan carefully — you only get one pick per token.
- Robux: 599 Robux on the powers board (persists always).
- Ascension: one free token per Ascension alongside 7.77× cash.
- Cannot target Hill Expansion or Space Staircase buttons.
