Addon: Flagbearer's Banners 3.0

Author: DarkChisaka

Flagbearer's Banners 3.0 expands faction building with medieval standards for castles, tournaments and battlefields. The collection includes sixteen colors and several shapes, including square and rectangular sashimono banners and tall flagpole variants.
A dedicated Banner Table is used to craft the new designs. Large standards can mark a settlement or army camp, while smaller banners work well in formations and ceremonial areas.

Flags can also be carried in the offhand slot, allowing a player to act as a standard-bearer while keeping the main hand free. The addon works without experimental world options.

Offhand support lets a standard-bearer stay recognizable during movement and combat, while the large variants establish permanent faction landmarks.
How to install the add-on
Download the .mcaddon or .mcpack file, open it with Minecraft and wait for the import to finish. Then enable the resource and behavior packs in the world settings. If the add-on requires experiments, turn them on before launching the world.
