Weapon Perk

Almost all weapons of uncommon or higher rarity have perks and upgrades that can be unlocked by earning experience with the weapon equipped. Perks typically come in the form of different optics, adjustments to attributes, special abilities and increased attack power. In almost all cases, the rarer the weapon, the more perk choices that are available.


 * Weapons typically have the following perk and upgrade options available:

Legendary and Exotic weapons acquired after Update 1.2.0.1 can only have their attack power improved by being ascended.
 * Uncommon: Two optic/attribute options, one ability and one damage upgrade.
 * Rare: Three optic/attribute options, one ability, two abilities and/or attribute adjustments and two damage upgrades.
 * Legendary: Three optic/attribute options, two abilities, three abilities and/or attribute adjustments and five damage upgrades.
 * Exotic: Three attribute adjustment options, two abilities (one or more possibly unique), three abilities and/or attribute adjustment options, and five damage upgrades.

Before perks can be used, they must be purchased with Glimmer and/or other upgrade materials such as Weapon Parts. Legendary weapons require Ascendant Energy for the last few damage upgrades. Exotic weapons require an Exotic Shard for the last damage upgrade. Perks/upgrades in the same column, such as optics, can be swapped for free once purchased.
