Banners (decorative)

Banners are decorative furniture items that 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 in a given world. When placed, Monster Banners provide a minor buff to nearby players which gives increased damage and defense against the corresponding monster.

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 272 Banners: 243 Monster Banners (91 pre-Hardmode, 152 Hardmode), 4 crafted, 6 Faction Flags, 3 Floating Island, 6 Underworld, 3 Pyramid and 7 Unobtainable banners.

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 placed, a Monster Banner provides a buff against its corresponding monster within a 50-block radius. This buff does not stack with other banners of the same type, though banner buffs against multiple different kinds of monsters can be acquired and will be consolidated into a single buff. The effects are as follows: Note that these effects apply before taking the defense into account.
 * Your damage to the type of enemy is multiplied by 1.5 (2 in Expert Mode).
 * The enemy's melee attack damage is reduced by 25% (50% in Expert Mode).

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 Banner is one of the rarest items in the game because Nymphs rarely ever spawn.
 * To some degree, the banner buff seems to counteract the improvement of the monster's ability in Expert Mode.
