Reverse-engineering Aion 2's network protocol for a real-time DPS meter

A developer built a combat analytics tool for Aion 2 by reverse-engineering the game's undocumented binary protocol. The Rust + Tauri app passively captures TCP traffic, parses varint-heavy packets that change with patches, and handles tricky entity identity issues. It also implements an rDPS attribution model to credit support classes for buffs and debuffs.
