Chances and Economy
Chance Roll
Section titled “Chance Roll”Each confirmed attempt generates a random integer from 1 through 100. The upgrade succeeds when that number is less than or equal to chance. For example, chance: 75 succeeds on 1 through 75.
A failed roll consumes the recipe’s reserved from.amount and gives no result. Required ingredients follow the global failure-removal setting.
Economy
Section titled “Economy”coin is checked through Vault before the chance roll. If the balance is too low, the menu closes and returns the reserved source item. The configured amount is withdrawn only after a successful roll.
When Vault or an economy provider is unavailable, Item Upgrader treats the balance as unavailable and skips both the insufficient-balance check and withdrawal. Install and verify both plugins before using non-zero prices.
Display Placeholders
Section titled “Display Placeholders”Result names and lore can display %price% and %chance%. Lore also accepts %needed_coins% for compatibility with existing configurations.
These values are display substitutions only. The coin and chance fields remain authoritative.
