There are a lot of ways to get banners in King of Avalon. Many are free if you’re willing to wait. Then there is the option to pay and get as many banners as you can afford.
Free to Play
Outside of the free options below you can also get free banners if an alliance member buys an Alliance Prestige pack or if Merlin is feeling generous and offers 20.
Spirit Altar
The Alliance Spirit Store has unlimited banners available as long as the alliance has enough Ceremony Crystal’s to stock and you have enough Spirit Coins to buy them. They cost 16 crystals or coins per banner.

Most alliances select The Wander Spirit which returns free banners every week! If you are active and run a few alliance events each week it really isn’t difficult to unlock all the chests. In total there are 3,575 banners via the Alliance Celebration tab every week. Free.
Magic Spire
You can purchase up to 300 banners every day from the Magic Spire. You must pass floor 5 to access the banners. Easy enough for any main.
Pay to Play
Deals of the Day
You used to be able to acquire these on Saturday; however with the appearance of Dragon Emblems this deal of the day was replaced with emblems. Since prestige cannot be applied past stronghold 35 the demand for banners has dropped. I personally managed to get every building to 30 on prestige without spending a dime on banners.
Packs
There are two packs you can buy to get banners. The banner pack and the alliance prestige pack. Only the alliance prestige pack will share with your fellow alliance members. Samples of these packs are below.
Each chest can drop 1400 to 1500 banners.
