Java 26.3; XP are individual points, not enchantment levels. For a new mob kill: 10 XP; every 100 accumulated XP give a level, maximum 100.
Buying a skill spends an XP wallet but does not lower the level. Class is selected once; re-study does not cancel points. Progress is maintained after death and /reload.
The passive effects of the form list are maintained without active spells. Leave stops updating the effects; the latter will expire in two seconds. Countdown is limited to 10,000 homicides/s and 100 million XPs.

Java 26.3; XP — отдельные очки, не уровни зачарований. За новое убийство моба: 10 XP; каждые 100 накопленных XP дают уровень, максимум 100.
Покупка навыка тратит кошелёк XP, но не понижает уровень. Класс выбирается один раз; повторное изучение не списывает очки. Прогресс сохраняется после смерти и /reload.
Поддерживаются пассивные эффекты из списка формы, без активных заклинаний. Leave прекращает обновление эффектов; последние истекут через 2 секунды. Учёт ограничен 10 000 убийств/сек и 100 млн XP.
