A shieldbow is a class of Ranged weapon that was introduced along with the Evolution of Combat. It is a longbow with a shield-like attachment that provides defensive bonuses to armour and life points. Shieldbows largely replaced longbows after the Evolution of Combat, which were simply slower versions of shortbows with a greater range. However, many longbows, such as the crystal bow and zaryte bow, were not converted into shieldbows, but instead to shortbows.
Effectively, a shieldbow is similar to a one-handed crossbow wielded alongside a shield. The primary differences are that a shieldbow uses arrows instead of bolts as its ammunition, its attack speed is Average, it deals slightly more damage, and it counts as a two-handed weapon for the purposes of some Ranged abilities. Because of its attachment, a shieldbow also counts as a shield for the purposes of most Defence abilities.
Shieldbows have a lower damage value than shortbows because of their defensive properties. The attack range of most shieldbows is 8.
