Configuration: All EXP rates are fully customizable via config/battlegrowth.json, which is automatically generated with sensible defaults on first launch and self-updates if new config keys are added in future versions. Requirements: Must be installed on both client and server. How it works: Every time a Pokémon lands a hit, dodges an attack, uses a buff or debuff move, or performs a support action, it earns EXP immediately. Knocking out an opponent rewards a bonus EXP payout on top. When enough experience is accumulated, the Pokémon levels up instantly mid-battle — HP bar and stats update on the spot without waiting for the fight to conclude. Gameplay balance:
