Banners (decorative)

Banners are decorative furniture items that provide a minor buff to all nearby players. This buff increases the damage that the player deals to the enemy displayed on the banner, along with a decrease in damage taken from that enemy. Banners can be placed on the underside of blocks. There are four crafted Banners (red, green, blue, and yellow). There are also several that are found naturally placed in various biomes, or are dropped from enemies. All Banners are purely decorative, and have no function.

Banners that drop from enemies are known as Monster Banners. Nearly every enemy in the game has a corresponding Monster Banner, each of which drops after every 50th kill of the respective enemy. Every 50th kill will be announced in the server chat, along with the enemy and the player killed it.

Faction Flags are Banners found in Dungeons. In post-Plantera worlds, the Faction Flags found hanging in a particular Dungeon area correspond to the background wall type (brick, slab, or tile), both of which signify the types of enemies that will spawn there. See Dungeon for more info.

There are currently a total of 109 Banners: 87 Monster Banners (46 pre-Hardmode, 41 Hardmode), 4 crafted, 6 Faction Flags, 3 Floating Island, 6 Underworld, and 3 Pyramid.

Orientation
Each banner may be placed in a right-facing orientation or a left-facing orientation, but this is not decided by the player. A banner placed in a specific "column" in the world will always face one specific direction. Placing it one block to the left or right will flip the orientation, resulting in alternating left- and right-facing "columns" which decide the banners' placement. Two identical banners with an even number of blocks in between each other (including zero blocks) will always face different directions, while banners with an odd number of blocks in between each other will always face the same direction.

Trivia

 * The four craftable banners correspond to the team colors in multiplayer.
 * The left half of the Nymph Banner is of the Lost Girl "NPC", while the right half is the Nymph monster.
 * Bosses don't have banners- instead they have trophies.
 * The Nymph Banner is a rare drop from the Nymph, the rarest enemy in the game, making it the rarest item in the game.
 * If you manage to defeat Skeletron and you need coins, take of all the banners you find in the dungeon. Each banner sells for 20 silver, and five banners will make one gold coin.
 * The Spike Ball only spawns in areas marked by the Marching Bones Banner.
