In order to upgrade your guild's level, you will need to invest various resources. In the 'My Guild' section, you will see a shield with the guild's current level, guild bonuses, and an indicator that needs to be filled. Next to the indicator is a 'Level up' button.If you click on it, you will see an option for the contribution. 2 more options will appear randomly. Note that more valuable resources will contribute more to the guild's progress.
New Guild System
Last Updated: 199d
We’ve changed the guild system and the mechanism for levels’ increasing.
From now on, the maximum level is increased: players can upgrade their guilds to level 45.
To upgrade the guild’s level, players need to get a certain amount of guild experience. The higher the guild level becomes, the more guild experience is required. More powerful guilds have bigger bonuses.
Also, as the guild level increases, the number of guildmates can grow to 30 (this number can’t be reduced).
When a guild reaches level 40, it will be able to upgrade 5 bonus levels. However, each additional level has its own burn rate. So if the guild wants to keep the level, the players have to keep the amount of guild experience for that level.
