Clan Missions is an essential part of the game, the purpose of which is to reward players for teamwork. To get the Reward, each player has to contribute the required number of Mission Points.
After you claim the bonus items, they are added to the Vault. Open the Bank (Chest icon in the top right corner of the screen) and choose the Vault tab.
You won’t receive a reward if:
You have not earned enough Mission Points;
You were excluded from the Clan before the end of the Mission;
You left the Clan before the end of the Mission.
N.B. All the Points gained during the Mission reset if a player leaves the Clan or gets excluded by the Clan leader. If a player joins the same Clan after the end of the Mission again, he won’t be entitled to receive the reward even though he had contributed enough Points before leaving the Clan.
