A shorter-strung bow, designed for rapid fire from the hip, rather than long-range sniping.
The Swift Bow features a high ammo reserve (which can be further extended with Talent selection) and extremely fast 'hip fire' (as of the WoM update, the primary attack key can be held down for repeated shots-- ideal for suppressing a horde or saving allies who are surrounded). Be aware that the hip fire has absolutely no armor penetration and minor headshot damage against armored enemies. Aimed shots gain significant penetration and damage against armor, so always aim against these targets. Unlike some longbow/career/talent combinations, swiftbows never have a visual zoom, making sniping a player-skill affair.
