About

A medieval SAO-themed class and skill tree system. Players choose one permanent class (Warrior, Mage, Archer) and unlock skills through a progression tree. Features class-specific abilities like mage mantras (rock throw, thunderstorm), stat upgrades (health, damage, speed), and a GUI-based skill system. Only server owners can reset player classes. Includes particle effects, cooldowns, and full data persistence using JSON file storage.
