Bow

General
A Two-Handed projectile weapon that causes piercing damage, there are a variety of bows in Guild Wars. The Ranger's Marksmanship attribute improves the damage of and is generally a requirement for this weapon type. Bow Attacks can only be performed when equipped with a bow.

Bow Classes
There are five different classes of bows, each of which has different range, attack speed, arc size, and projectile speed. Refire rate directly affects the DPS of the bow. Additionally, arc size also affects the pathing of the arrow -- some obstacles might obstruct a bow with small arc size, but a bow with large arc size may be able to fly over the obstacle.

1 Range is approximated in the radius of the aggro circle measured on approximately flat ground. 2Flight Time is for a target at Shortbow range distance.
 * Being at a higher elevation than your target increases the range your arrows can reach, and at a lower elevation your range is shortened. Having height advantage to your target will also increase your damage by up to 50%, depending on the amount of elevation.
 * Note that Guild Wars does not factor in accuracy of bows the same way other games do. Accuracy is determined by Flight Time and Arc Size.

Max damage range of a bow is always 15-28, regardless of bow class. Bows with maximum damage have been observed with attribute requirements as low as 7. Bows with an attribute requirement of 0 have been observed with damage ranges as high as 9-13, although the Candy Cane Bow, an item from Wintersday 2007, 2006 and  2005, does 15-15 damage (modified normally) but has no attribute requirement.

Upgrades and Modifiers
The weapon upgrades for the bow are Bow String (prefix) and Bow Grip (suffix).
