Weapon perks

Introduction

#	Description
	Equipped weapon gains experience by killing NPCs or via Upgrade Parts. With enough experience, new perks unlock, and the item's color changes. Weapon perks have ranks that determine their power level; they are mainly influenced by Item Luck.
Perk 1-3	The first three perks are always predefined.
Perk 4	The fourth perk can be chosen via a dialog window once unlocked. However, if you level up your weapon using Upgrade Parts, this perk will be random.
Perk 5	The fifth perk is always random.
Legendary Perk	The sixth perk, a.k.a. the "legendary" perk, is selected from a separate table of perks. Its effect applies only against NPCs.
Perk 7	Every weapon can be upgraded by Roger or Cotsford (Vegas) to gain one additional perk.

Rerolling

Weapon perks can be rerolled by Boyce in Junktown or Randal in New Vault City. The cost is in local currency and applies to a single reroll. Since the outcome is randomized, multiple rerolls will likely be necessary to achieve the desired perk configuration.

Level	Cost
1	10,000
2	75,000
3	150,000
4	1,000,000
5	5,000,000

Weapon experience

The total amount of gear experience (gear XP) required for weapons to level up depends on its tier, type, and current level.

Total XP needed for a weapon to level up = Base XP Requirement * XP Requirement Multiplier

Base XP requirement and Experience modifiers to get specific equipment to a specific level can be seen in tables below: NOTE: Patch 5.4

Base weapon XP required to level up per tier

Itemized gear upgrades

There are two item types that can help your gear achieve the optimal perk configuration: upgrade parts (which provide an immediate gear XP boost), and gear mod upgrades (which have a chance of increasing the rank of your already unlocked perks).

Weapon XP boosters

Found mostly in dungeon lockers, Upgrade Parts add experience directly to your weapons. Note that any perks unlocked via this method will be randomized, even if you would normally be able to select the one you want.

To use Upgrade Parts on an item: (1) place the weapon on the ground; (2) click and hold the left mouse button on it; (3) from the drop‑down menu, select the bag icon; (4) in the inventory window that appears, click on the stack of Upgrade Parts you wish to use.

Gear experience boosters

Image	Name	Description
	Upgrade Parts	Adds 10,000 XP to a piece of gear
	Upgrade Parts MKII	Adds 100,000 XP to a piece of gear
	Upgrade Parts MKIII	Adds 1,000,000 XP to a piece of gear

Weapon perk rank upgrades

If the rank of the perks on your weapon could use a little tune-up, there are several items that you may find interesting, see the table below.

To use any of them: (1) place your weapon on the ground; (2) click and hold the left mouse button on it; (3) from the drop‑down menu, select the bag icon; (4) in the inventory window that appears, click on the item you wish to use. Alien weapons are only compatible with GMU1000.
