Once the war is complete, your individual winnings of loot from the war will be loaded into your clan castle. You may leave this loot in your clan castle or collect it.

When it is in your clan castle, a portion (10%) can be lost during an attack on your base just like a storage. There is also a maximum amount of loot that your clan castle can hold. Be sure that there’s enough room for new loot. When you collect your clan castle loot, it will be moved to your regular storage and can be used and lost as usual.
