XP & Levels

Cubic curve, NO level cap.

XP sources

Kill: each species gives its own fixed XP (see "XP per kill" on the Pokémon's page).
A kill gives XP to the trainer AND to the active Pokémon — two independent levels.
Pokédex: +25% XP (one-time bonus per species, after 100 kills).
Tasks, Quests and Game Pass also pay XP.

The curve

Total XP for level L = round( 50/3 × (L³ − 6L² + 17L − 12) )

There's no cap — the level is infinite (the curve just gets more expensive).

💡 Multipliers: VIP, XP Boost (1h) and Streak Points (+0.1%/point) add up on top of the kill's XP.
