The Rally Flag is a permanent cosmetic decoration in Clash of Clans that costs 15,000 Elixir and requires Experience Level 12 to unlock. Players can purchase up to one of these flags, which serve no gameplay or defensive purpose but allow for base personalization. The Rally Flag is primarily used to visually indicate a preferred attack point for clan members during clan war attacks, though it does not enforce or direct troop behavior. It can be placed in the main village area alongside buildings or on the outer edges reserved for obstacles and decorations.
