trades, one wagon each. Unlocking more squads makes more wagons available.
at most to escort a wagon. A hero can only escort one wagon at a time.
a day on other lords' wagons, and each wagon can only be plundered twice.
How it works
You pick a wagon, give it an escort of heroes, and it sets off on a random route. On the way, other lords can attack it and steal part of its cargo. When it arrives, you claim whatever is left.
Two things raise the value of the cargo: the wagon's rarity and your Castle level.
Going for a rare wagon
Before it leaves, you can refresh the cargo: the first refresh is free, the next ones cost Trade Contracts. The more you refresh, the more likely a rare wagon becomes.
| Refreshes | N | R | SR | SSR | UR |
|---|---|---|---|---|---|
| 1 | 50% | 30% | 10% | 5% | 5% |
| 2 | 30% | 30% | 20% | 10% | 10% |
| 3 | 20% | 20% | 30% | 15% | 15% |
| 4 | 0% | 20% | 40% | 20% | 20% |
| 5 | 0% | 0% | 50% | 25% | 25% |
| 6 or more | 0% | 0% | 0% | 0% | 100% |
In short: from the 6th refresh (the free one included), the wagon is always UR. If you have enough contracts, that is the surest way to make a trade pay.
