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 from damage taken from that enemy. If you have a banner buff against a specific type of enemy, your damage dealt to it will increase drastically and its damage to you will decrease drastically, especially in Expert Mode. 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.

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 121 Banners: 99 Monster Banners (50 pre-Hardmode, 49 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.

Banner Buff
When you have a banner buff against a specific type of enemy, the effects are: Note that the multiplication occurs before taking the defense into account.
 * Your damage to the type of enemy is multiplied by 2 in Expert Mode and 1.5 in normal mode, no matter melee or projectile.
 * The enemy's damage is multiplied by 0.5 in Expert Mode and 0.75 in normal mode, but it seems that only melee attack applies the rule.

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. These trophies do not however grant increased damage to and resistance from the boss like banners.
 * The Spike Ball only spawns in areas marked by the Marching Bones Banner.
 * The Nymph and White Cultist Archer Banner are two of the rarest items in the game because both monsters rarely ever occur.
 * To some degree, the banner buff seems to counteract the improvement of the monster's ability in Expert Mode.
