There are three levels of Clan Shields.
Clan Shields can be selected by the LEADER and LIEUTENANT(S).
It is worthwhile for the Clan to decide whether or not to buy a Shield by voting, but the final decision is also the LEADER(S) and LIEUTENANT(S).
1. BRONZE SHIELDS
Not unique, free Shields. Higher level Bronze Shields become available depending on Rank List results.
2. SILVER SHIELDS
Can be bought with Gold Coins. They are NOT unique. Higher level Silver Shields become available depending on Rank List results.
3. GOLD SHIELDS
Custom Shields that can be bought for Gold at auction. Only a few Shields are auctioned off per week.
The Clan Shield can be changed in the Clan Profile page.
