🗡️ Aion 2 DPS Meter
A lightweight, network-based DPS meter for Aion 2. It passively reads game packets off the network interface — it does not modify, intercept, or interact with the game client or server in any way.
⚠️ Disclaimer: This tool only reads network traffic on your local machine. It does not inject code, modify memory, or communicate with any external service. All combat logs and data remain strictly on your local machine; this tool does not share, upload, or transmit any data to external resources. Use at your own discretion and in accordance with the game’s terms of service.

📦 Installation
Step 1 — Install Npcap (required)
Download and install Npcap from https://npcap.com/#download.
⚠️ During installation, you must check “Install Npcap in WinPcap API-compatible Mode”. The meter will not work without this option enabled.
Step 2 — Download the latest release
Go to the Releases page and download the latest .zip archive.
Step 3 — Extract and run
- Extract the
.zip to any folder of your choice.
- Run
AionDpsMeter.UI.exe — no installation needed.
- Launch Aion 2 and start playing. The meter will automatically detect the game traffic and begin tracking.
Note: You may need to run the application as Administrator depending on your system’s network capture permissions.
❓ FAQ
Q: Why is my nickname displayed as Player_xxxx?
- The server does not include player nicknames in damage packets. A nickname is only sent in specific events, such as teleporting or entering a dungeon. Until one of those events occurs, the meter displays a placeholder name.
Q: Why are some summon skills registered as a separate unknown entity?
- This is a rare edge case. It happens when a summon is spawned outside your render range, meaning the meter missed the summoning event and could not link the summon’s ID to the owning player.
Q: Will there be support for other languages?
- No. It’s too much effort, and the translation will not be accurate anyway.
