This feature has been removed from the game.
Ranged was a category of skills. It included bow, pistol, assault rifle, machine guns and sub machine guns, shotgun, rifle and sniper-rifle, ranged energy weapons, fling shot, aimed shot, burst, full auto, bow special attack, and multiple ranged weapons.
The 18.7 patch removed the ranged category. It placed pistol, bow, SMG, assault rifle, shotgun, rifle, ranged energy, and multiple ranged into a new ranged weapons category, and fling shot, aimed shot, burst, full auto, and bow special attack into a new ranged specials category.
