There are five Tribe Clan leagues in the game:
1. Wooden
2. Stone
3. Rune
4. Golden
5. Crystal
The higher the league, the more difficult the tasks and the more valuable the rewards.
All new tribal unions fall into the first (wooden) league.
If your clan takes places 1-3 in the competition, then you will rise to a higher league.

If your clan takes one of the last 3 places, you’ll be moved to a lower league.
Note that if there are more than 5 clans in the room, then the last 3 clans, starting from the 5th place, drop 1 league lower. An exception is the first, Wooden league, as it is the lowest.
Example: If there are 5 clans in a room, then 3 go higher, 1 remains in the same league and 1 flies to the bottom.
If there are 7 clans in the room, then 3 go higher, 1 remains in the same league and 3 go down.
If there are 4 clans in a room, then 3 go higher and 1 remains in the same league.
