Check the bonus-die supply at the next biome
Bonus dice are limited within a biome and refresh when you enter a new one. Buying another die type changes your available choice; it does not mean you can spend unlimited bonus rolls in the current stage.
Track uses before choosing the next challenge
- Check the supply when a dice event displays it, especially after a biome transition.
- Keep track of each bonus die spent so you know the remaining reserve before choosing a reward.
- Compare the failed roll's shortfall with the selected die's possible effects.
- Spend on a useful reward, then update your remaining count.
A fresh supply still does not guarantee success
The bonus roll can still fail to reach the reward threshold. Do not commit to a difficult option assuming the interface will reveal a spare die afterward. Use the current displayed supply rather than assuming a fixed count for every situation.
