Debris field
How it's calculated. Moon chance = 1% per every 1000 units of debris (Metal + Crystal), maximum 20%. Debris is left only by destroyed fleet (50% of its cost) — defenses leave no debris. The chance check is one-time, right after the battle.
| Debris in the field | Moon chance |
|---|---|
| 5 000 | 5% |
| 10 000 | 10% |
| 15 000 | 15% |
| 20 000 and more | 20% (cap) |
