Experience Points

Experience points are a reward for completing specific tasks or defeating non-player enemies in combat. More experience points are required to attain higher levels. For example, you need a total of 1000 xp to get to level 2, and a total of 210,000 to attain level 21.

NOTE: No xp is earned for killing player characters.

What can earn you some experience points

Killing non-player enemies. The more powerful your enemy is, the more experience points you get.
Total XP = (( HP x 2 + AP x 15 + each DR * 3 ) x 2(if Boss) ) * their own exp multi.

On encounter everything which is human, ghoul, mutant or robot have 100%, rest have 250%.
Completing a quest.
Using your skills successfully (Repairing an item, healing someone, etc.).
Avoiding a random encounter on the world map.
On a special occasion from a Game Master (e.g. for winning a contest etc.).

Weapon and Armor Experience

Your worn equipment gains experience points from kills alongside you, gaining perks specific for every armor and weapon. Only currently equipped armor and weapon in active slot will gain experience. You can view the current experience, experience required for the next level and unlocked perks on a piece of equipment by examining it.

Full list of equipment perks can be seen here:

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

Total Experience Needed = Base Experience Needed * Experience Needed Modifier

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

==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 (in Salt Lake) or Cotsford (in Las Vegas) to gain one additional perk.

1	10,000
2	75,000
3	150,000
4	1,000,000
5	5,000,000
6	50,000,000
7	50,000

Weapon experience

The total amount of gear XP required for a weapon to level up depends on its tier, type, and current level.

Total XP required for a weapon to level up = Base XP requirement * XP requirement multiplier

The tables below show (1) the base gear XP required to level up your weapon depending on its tier, and (2) the base gear XP requirement multiplier by weapon type.

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.
