Lu4: Fatigue System

Lu4 29.01.2026


Basics

The Fatigue System was introduced in the Lu4 to balance the progress between active players and those who spend less time online. It affects how much experience a character can gain per day.


Character State

Each character in the game can be in one of two states. Checking the current state of a character is quite simple — hover your cursor over the hourglass icon in the bottom right corner of the game interface.

icon l2 — Battle Ready State.

  • Normal state of the character
  • The character receives 100% experience for killing monsters and Raid Bosses
  • Fatigue Points (Exp) are consumed in an amount equal to the experience gained

icon l2 — Battle Worn.

  • Fatigue limit exhausted
  • Experience for killing monsters and Raid Bosses is reduced by 10 times
  • Fatigue Points are not consumed
icon l2

Fatigue does not affect experience gained from other sources and does not change the mechanics of Fatigue accumulation.


Gaining Experience

The Battle Ready state affects the amount of Experience a Character receives.

Let's take an example with killing a monster Werewolf Hunter Werewolf Hunter Lv. 10 , which gives 276 Experience upon death.

  • Character in Battle Ready state:
    • Receives 276 Experience
    • Spends 276 Fatigue Points
  • Character in Fatigued state:
    • Receives 27.6 Experience
    • Fatigue Points are not consumed

Fatigue Points are not consumed if experience gain is disabled with the .expoff command.

The system does not limit experience gained outside of combat — it only applies to experience from monsters and Raid Bosses. Quests grant full experience regardless of Fatigue state.

The exact amount of experience depends on the level difference between the character and the monster. Learn more in the article Experience Gain and Penalties.


Fatigue Recovery

Fatigue Points are automatically replenished daily at 06:30 server time. The number of points depends on the current stage of server development.

If the limit has not been exhausted, the new points are added to the remaining ones. After replenishment, the character automatically returns to the Battle Ready state.

Example: The character had 1 000 000 points. At 06:30, they received another 2 500 000. The new total is 3 500 000 points.

Fatigue Points can also be replenished manually using special items, for example: Greater Battlesurge Elixir Greater Battlesurge Elixir NG

Elixirs can be obtained as special rewards for activities, such as entering promo codes in the Personal Account.


Experience Loss

Character death in PvE and PvP affects experience loss differently depending on the state:

  • Character in Battle Ready state:
    • Standard Experience loss, regardless of death type
  • Character in Fatigued state:
    • PvE — Standard Experience loss
    • PvP — Experience loss is reduced 5 times: down to 20% of the standard amount
