EXP Formulas

Bonus EXP

EXP bonuses are expressed as a percentage of the base rate and stack additively with each other.

Formula:

Final_EXP = Base_EXP × base_rate × (1 + bonus1 + bonus2 + ...)

The effective rate shown by @rates is base_rate × (1 + all active bonuses):

Active bonuses Effective rate Example (1 000 base EXP)
None 5 5 000 EXP
+25% map bonus 6.25 6 250 EXP
+100% Field Manual 10 10 000 EXP
+25% map & +100% Field Manual 11.25 11 250 EXP

Current bonuses that stack:

  • Weekend bonus: +50% (active on weekends)
  • Bonus EXP Map: +25% (active when on a randomly selected bonus map)
  • Field Manual: +100%

Example: killing a monster that gives 1 000 base EXP, with a weekend bonus (+50%), an active bonus map (+25%), and a Field Manual (+100%):

Effective_rate = 5 × (1 + 0.50 + 0.25 + 1.00) = 5 × 2.75 = 13.75
1 000 × 13.75 = 13 750 EXP

Tip

Use the @rates command in-game to see the current effective rate including all active bonuses.

Party Share EXP

Party EXP sharing applies two separate bonuses on top of the server rate:

  • Tapper bonus: the first attacker is the baseline, then, each additional attacker who dealt damage adds +15% to the mob's total EXP before the party split. 5 tappers = +15%×4 = +60%.
  • Party member bonus: the first member is the baseline, then, each additional party member boosts the shared pool by +10%, then it is divided equally. 5 members = +10%×4 = +40% to the pool.

Formula:

EXP_per_member = Monster_EXP × (1 + 0.15 × (T − 1)) × (1 + 0.10 × (N − 1)) / N
Variable Description
Monster_EXP EXP value the monster gives at the current server rate (including active bonuses)
T Number of players who dealt damage to the monster (tappers)
N Number of eligible party members on the same map (alive and not idle)

Example: a 5-member party kills a monster worth 1 000 EXP (after server rate and active bonuses), all 5 members attacked it:

Tapper bonus : 1 000 × (1 + 0.15 × 4) = 1 000 × 1.60 = 1 600
Party bonus  : 1 600 × (1 + 0.10 × 4) = 1 600 × 1.40 = 2 240
Per member   : 2 240 / 5 = 448 EXP

Info

Idle members (no action for 120 seconds) do not receive shared EXP and are excluded from N, but they still count as tappers if they dealt damage before going idle.
