• With buff, some damage Dished out by nearby teammates Comes back as healing

The Concheror, is a promotional secondary weapon for the Soldier. It is a light brown wooden box with dark brown corners and a quad diamond shaped insignia, accompanied by a conch shell. A white, slightly tattered, vertical banner flag with the same diamond insignia secured onto a pair of bamboo sticks appears when the banner call is played.

The Concheror functions in a similar manner to the Buff Banner and the Battalion's Backup, as they provide a specified effect for surrounding teammates. This banner charges through a combination of either dealing or receiving damage. Like the Buff Banner, holding down the primary fire button will delay the effect until the button is released. While this banner's buff is active, allies within 450 units are healed for 35% of the damage they deal.
