Level

Level is a number between 1 and 1000 that reflects your character's skill and experience.

Every time you level up, you get a set number of skill points (based on your Intelligence).

Up to level 18, leveling up increases your hit points (based on your Endurance)

Every three levels up to level 27, you get to choose one level perk to add to your character; select it quickly lest you lose it.

Starting at level 55, you start getting PvE Perks at the rate of one perk every five levels, plus one more for every 5 points of Charisma you have, up to a total of 5 PvE perks per level.

Level progression gets progressively harder: each level up imposes an additional penalty of -0.1% on the amount of XP you gain while increasing the XP requirement for reaching the next.

XP needed to go up one level = Current level * 1000

Total XP needed to level up = Current level * [(Current level - 1) * 1000) / 2

Note that the above formulas are not adjusted for the -0.1% XP/level penalty, which always applies as the final step to all XP gains:

Final XP earned = Total XP - [Current Level * 0.1%] * Total XP (note that [Current Level * 0.1%] cannot exceed 99%)

Experience points

Experience points (XP) are a measure of your progression towards the next level. They are rewarded for completing specific tasks, such as quests, or defeating non-player opponents (killing players awards no XP). The higher your current level, the more experience you are going to need to reach the next. For example, you need a total of 1000 XP to get to level 2, but a total of 210,000 (rather than 20,000) to reach level 21.

XP per kill formula

The more powerful the critter you defeat, the higher its XP reward:

Total XP reward = [(HP x 2 + AP x 15 + DR point sum * 3 ) x 2 (if boss)] * XP multiplier, where:
HP = the critter's hit points;
AP = its action points;
DR point sum = its damage resistance values put together;
"Boss" means a critter with the word "BOSS" displayed next to its HP, and XP multiplier is generally either 1 (for humanoids) or 2.5 (for non-humanoids).

Alternate XP sources

If you're tired of massacring NPCs, some amount of XP can also be gained from:

• Completing quests
• Successfully using some of your skills (e.g., First Aid awards 3 XP for each hit point you manage to restore)
• Detecting random encounters on the world map
• Participating in/winning contests/events

Character XP gain multipliers

• Everyone starts with 100% as their base XP gain multiplier
• Loner: +10% (Regulators get 10 times that!)
• Swift Learner: +10% XP
• Charisma: +2% XP per point

• With each level, you get 0.1% less XP

Gear experience

Your equipment receives experience points from kills alongside you, unlocking perks as it levels up. Only your currently equipped armor and active slot weapon are eligible to gain experience. You can view your gear's level progression/perks by left-clicking its inventory screen ("I" by default) icon.

For a complete list of weapon/armor perks, see weapon perks and armor perks respectively.

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

XP needed to level up = Base XP requirement * XP requirement mod
