Features persistent character-based storage via Lilia's character system, comprehensive client-side UI with progress visualization, administrative panel for monitoring all player achievements with search functionality, automatic progress updates through game hooks (OnNPCKilled, PlayerDeath, OnItemAdded, OnCharVarChanged), and support for both simple single-criteria achievements and advanced multi-stage objectives. Includes achievement completion notifications, color-coded status indicators, and tooltip information displays.
