Daeva Lens

English · Türkçe: docs/tr/README.md

Daeva Lens is a DPS / healing meter and boss helper overlay for AION 2. It reads a passive, read-only copy of the game traffic reaching your network card (via Npcap) and shows damage, healing, damage taken, boss and dungeon history, boss timers, player ratings and a skill rotation timeline. Interface: English / Turkish.

Meter panel	Position lock

Skills	Settings: panel and meter

Settings: sounds	Settings: privacy	Settings: window and data

All images are the real interface, captured while replaying a local recorded test session (not published) with Streamer mode on, so names appear as aliases. No live game was used. The recording comes from real gameplay (a packet recording replayed inside the program), and the player name is masked.

Features

• DPS, healing (HPS) and damage taken: group and personal views, share, crit rate, per-skill breakdown, death recap.
• Boss and dungeon history: every boss fight is saved; in dungeons the main boss (last boss) closes the run card.
• Four tabs: Boss and Players, Skills, Timers, Settings.
• Sounds hub: all sound and voice settings in one place (Settings > Sounds).
• Boss timers: same schedule data as shugo.gg, region selection, beep or spoken alert in English or Turkish.
• Player ratings and blacklist: rate players, keep notes, optional red alert when a blacklisted player is in your party. Stored only on your PC.
• Skill rotation timeline: per-player skill strip with zoom (wheel / +/- / Fit) and pan.
• Party display: option to hide party members who are not dealing damage.
• Streamer mode: names replaced with local aliases on screen.
• Quiet by default: sounds, on-screen notices, event timers and the extra panels are off by default and can be turned on in Settings.

Install

1. Install Npcap from https://npcap.com/#download (default options). Daeva Lens does not work without it.
2. Download the release zip from Releases and extract the whole folder somewhere permanent.
3. Run Daeva Lens.exe. No installation is needed. Settings and the log are written to the %APPDATA%\Daeva Lens folder. If auto-start is turned on (it is off by default), it is added to Windows startup.
4. Start AION 2. The panel fills in when combat begins.

SmartScreen note: the exe is not code-signed, so Windows may show "Windows protected your PC". Click More info > Run anyway. The exe is unsigned because a signing certificate costs money and this is a free hobby project. Antivirus tools may also give a false positive on unsigned programs. Free ways to build trust: you can scan the files on VirusTotal; you can report a false positive to Microsoft at https://www.microsoft.com/wdsi/filesubmission. To verify your download, first compare the zip with the SHA256SUMS.txt file on the release page:

certutil -hashfile "Daeva-Lens-v2.2.1-win-x64.zip" SHA256

Then, after extracting the zip, compare Daeva Lens.exe with the matching line in the SHA256SUMS.txt file inside the extracted folder:

certutil -hashfile "Daeva Lens.exe" SHA256

Usage and shortcuts

Shortcut	Action
Ctrl+Shift+K	Position lock (prevents moving the panel by accident)
Ctrl+Shift+L	Click-through (mouse clicks pass to the game)
Ctrl+Shift+D	Show / hide the panel
Ctrl+Shift+R	Reset the meter

All shortcuts can be changed in Settings. Click a player for the skill breakdown; the gear icon opens the four-tab drawer. Full guide: GUIDE.md.

FAQ

• Panel shows no data: is Npcap installed? Restart the app after installing it.
• Cannot click the panel: click-through is on - press Ctrl+Shift+L.
• Cannot move the panel: position lock is on - press Ctrl+Shift+K.
• No spoken alert: needs a Windows voice for the chosen language; check Settings > Sounds.
• Panel not visible over the game: run the game in borderless/windowed mode.
• Reset everything: quit and delete %APPDATA%\Daeva Lens\.

Security and honesty

What the source code does (and does not do):

• It does not read the game's memory, does not inject code, and does not listen to your keystrokes (the only global keys are the Electron shortcuts above).
• It does not send anything over the network: no HTTP, update or telemetry code; boss timers use your local clock.
• To find the game, the helper program looks at the list of running processes and at the TCP and UDP connection tables (Windows system calls). It writes the processes whose name contains aion, ncsoft or purple to the log. It reads a passive copy of traffic through Npcap and never sends anything to the game server.
• Traffic recording to a local file is optional and off by default. Settings and data live in %APPDATA%\Daeva Lens\.

There is no official approval from NCSOFT. NCSOFT's published rules (plaync.com/policy/operation/aion2) neither explicitly forbid nor explicitly allow packet reading or overlay panels. No known ban case was found, but that is not an approval. No guarantee is given that you will not be sanctioned or banned; the risk is yours.

The helper a2co-capture.exe is also GPL-3.0 free software; its source is in capture/ (see BUILD.md).

Build from source

See BUILD.md (step by step: Node.js, npm install, npm test, npm run dist). The capture helper source is in capture/.

Full tests need local game recordings; for privacy reasons the recordings are not published, so those tests are skipped.
