Uniquely among the high-velocity launchers, the bombabarbardeer fires one rocket from each of the three muzzles of the cannon barrel, resulting in a shotgun-like rocket launcher mostly suited to short-to-medium range combat. Each firing still only uses one rocket ammo, and the magazine is generous, on par with a low-level Vanquisher. The downsides are a punishingly long reload time, and that the individual rockets are fairly weak. On average the total damage will be similar to a high-damage launcher of equal quality and level, but the individual projectiles deal slightly less damage than those of a Vanquisher.
Unlike the Vanquisher, the gatling barrel does not rotate when firing. That muzzle only rotates when it's mounted on a Vladof launcher.
