Weapon perks

Introduction

#	Description
	Equipped weapon gains experience by killing NPCs or using Upgrade Parts on it. When enough experience is earned, new perks unlock, and their color changes. Weapon perks have ranks that determine their strength and are mainly influenced by Item Luck.
Perk 1-3	The first three perks on tier 3 gear are always predefined. Some tier 4 items may have random perks even on the first three levels.
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, known as the "legendary" perk, is selected from a separate table of perks and only applies against NPCs.
Perk 7	Every weapon can be upgraded by Roger or Cotsford (Vegas) to gain one additional perk.

All perks on weapons can be rerolled by Boyce in Junktown or Vault 8 (yes there are two of him). The cost is in local currency and requires the same amount of currency as the experience required to get that level. The perk added by wattz cores or t4 parts can also be rerolled, which is listed as number 7 in the following table. Rerolling is random, so expect to potentially spend a lot of currency before getting exactly what you want.

3	150,000

Total amount of Experience required for equipment to level up depends on its tier, type and current level.
