After joining a clan you can participate in "Clan Wars". Team up with your allies and fight other clans in 1x1, 2x2 and 3x3 battles!
Each win grants you a certain amount of Glory points that are required to advance your technology and battle skills:
• 1x1 win — 1 Glory point
• 2x2 win — 2 Glory points
• 3x3 win — 3 Glory points
Every day the results of Clan Wars are announced, and top 20 clans that earned the largest amount of Glory points get a special reward: Artifacts. They will be given out to each player who won at least one battle that day.
Additionally, you receive 1 artifact for each battle won in a series of 3 wins, and scoring 5 Clan War wins grants you 2 Artifacts.
You can check the Artifacts available to you in the Psi-generator in your base.
In order to get a weekly clan reward, you need to win at least one clan battle.
