Calamity System
| Selection Formula | A calamity becomes eligible once either calamity level or mountain level reaches its minimum. Higher-tier calamities gain extra weight as calamity level rises, then the game picks from the weighted pool. |
|---|---|
| Trigger Effects | Each calamity trigger raises calamity level, starts an 8-second calamity window, runs the chosen event, and can reveal a den if the den-reveal upgrade succeeds. |
| Falling Rock Formula | Falling rocks use a weighted five-rock table. Stronger rock types become more likely as calamity strength increases. |
