Banner

The Banner is an outdated item that was previously obtained using bugs and exploits. Normal banners are not craftable.

Properties
Banners were obtainable through 2 main methods. The first one was breaking the banners in the Hub with the enchant while in an unprotected Dark Auction lobby. The second method was when the Traveling Zoo was first introduced, which cause the stands to spawn on player's islands, allowing them to break the banners.

Because the type of banner you were able to obtain didn't exist (WALL_BANNER), when the game tried to render them it caused a crash. The texture for these items in 1.8 was later changed to a stone block. Due to some glitches, banners became reasonably common, though they later became blacklisted to prevent game crashes. This makes them incredibly hard to transfer, and they will delete upon changing servers.undefined

Banners disappear when interacted with in many different menus, so one of the best ways to ensure they don't get deleted is to place them.

Trivia

 * An unknown update allowed for banner ids that were previously invisible in versions of 1.8 to become visible. It is unknown why these changes came into effect.
 * TimeDeo's video showed the NBT data of one of the banners at the end of his "how i lost 800,000,000 coins" video. As every other item in SkyBlock, the data includes, which classifies the item as wall banner (which, in vanilla, does not exist). ExtraAttributes is not used by Minecraft, but the plugins that the server runs on, which instructs the plugins to display that item in the player's inventory.
