Combat Detail (Buff Timeline + Damage Capsules)

• Global — Real-time DPS rankings for all nearby players
• Timer — Training dummy mode with 10s idle auto-finalize; DOT does not extend the timer
• Boss — Whitelisted bosses are tracked automatically; auto-finalize on boss death

The legacy Dungeon mode has been retired (old dungeon reports remain readable).

• QPainter custom rendering, high performance with zero lag
• Frameless window, drag freely anywhere on screen — including onto another monitor (edge-snapping removed in v9.4)
• Title bar control buttons: Reset / Personal Report / Expand Main Window (v9.0)
• "You" Marker — a slanted YOU tag on your own nickname capsule, so you spot yourself at a glance (v9.1)
• BOSS Summary Row — in boss fights the top ranking row shows boss name + team total damage + team DPS with a full red bar; the title bar slims to timer + kill mark (v9.3)
• Semi-transparent overlay, background opacity affects only the backdrop (text stays fully opaque)
• Normal / Mini size toggle (right-click menu)
• Right-click menu integrates all customization (size/damage format/DPS format/opacity/background/theme)
• Show Overlay Toggle — a checkable "Show Overlay" entry in the right-click menu; after hiding the overlay you can bring it back from the main window's right-click menu or the system tray (v9.4.1)
• Hover Skill Panel — hover over a player's rank row to see full skill breakdown
• Cast ECG — waveform visualization of skill cast rhythm (wave height = damage, wave color = cast speed)
• Buff Timeline — Gantt of buff cast timing + per-buff count capsules, color-coded by direction (v9.0)
• Damage Type Capsules — seven-type breakdown (Crit / Heavy / Perfect / Frontal / Back / Block / Multi-hit), aligned with the official meter (v9.0)
• DOT Classification — direct hits and DOT damage split automatically
• Auto-Position — the overlay restores its last position on launch, or sits center-right on the current screen the first time
• Metallic nickname text + class-colored gradient bars + hover glow effect + faction icons
• Pairing status indicator + real-time network latency (RTT) + accelerator detection
• 4K DPI auto-scaling
• Persistent settings (opacity/size/display mode auto-saved)

• Multi-level collapse (player-level + skill-level), skill hide/restore
• Region select analysis (Alt+drag) — cross-player stats for casts / damage / CPM
• Semantic-colored skill icon borders (crit red / strong orange / perfect purple / DoT cyan / heal green)
• Playhead-centered zoom, Fit button, combo chain grouping

• Skill breakdown: damage share, crit rate, average hit, specialization indicators
• Your Gear Score — combat detail shows your own gear score (v9.1)
• Skill timeline: cast sequence tracking for rotation and combo analysis
• Left/Right-Click Skill Coloring — skill names are colored by trigger key (light blue for left, orange-red for right) across combat details and the skill map (v9.4)
• "Frontal" Column — the skill table now covers all seven damage types, with Frontal placed between Perfect and Back; older reports have no such value and show 0% (v9.4.1)
• cHPS Healing Stats — combat detail, reports, and analyzer all support healing metrics
• Personal Report Window — one click on the overlay opens your latest 20 reports with full personal combat detail (v9.0)

• Full Report Upload — reports to the Aletheia community now carry every skill's full metrics and healing, powering class skill leaderboards and spec/stigma stats (v9.1)
• Automatic Report Upload (Free users) — compliant reports upload anonymously and automatically to the Aletheia Community (startup consent required); Sponsors have it off by default with manual target selection kept; teammates are always anonymous (v9.3)
• Server in Reports — uploads carry your server (for yourself and every participant), so community leaderboards can categorize by server (v9.4)
• Report Analyzer — compare performance against historical class averages, with DPS/HPS/speedrun modes
• Summon damage automatically merged under the summoner
• Healing skills tracked in a separate section (damage/healing don't overlap)

• Windows 10/11
• Npcap (check "Install Npcap in WinPcap API-compatible Mode" during installation)

1. Install Npcap
2. Download the latest version → Releases
3. Extract, then launch ALETHEIA-DPS.exe (right-click → Run as Administrator) — from v9.1 this is the entry point, with built-in auto-update
4. On first launch, sign in with Discord and agree to the report-upload terms (both required to enter the main window). Optionally activate an AION2-XXXX-XXXX serial for Pro — without it the main window is blurred, but the overlay and basic monitoring still work.
5. Launch the game and data will appear automatically

Hotkeys are customizable via right-click menu or settings.json.

Q: Why is there no data?

A: Make sure Npcap is installed (WinPcap-compatible mode), the application is running as Administrator, and the game is active.

Q: Latency shows a value but there is no damage data?

A: v8.0 automatically supports most game accelerators with candidate auto-switching. If issues persist, use the built-in environment diagnostics for self-diagnosis.

Q: Why does my antivirus keep flagging it?

A: Windows Defender's ML model may flag executables without an EV code signing certificate. Please add the main program and companion tools to your exclusion list. We plan to purchase an EV certificate when funding allows.

Q: How accurate is the data?

A: v8.0 includes combo chain grouping, DOT classification, skill merging, and improved damage-attribution precision. Godstone and summon damage are included in totals. v9.0 realigns damage-type classification (Heavy / Crit / Back / Multi-hit) to match the official meter 100%.

Q: The overlay isn't visible in Exclusive Fullscreen?

A: Exclusive Fullscreen bypasses the Windows DWM compositor, so all topmost overlays (Discord / Steam / NVIDIA included) stop rendering. Use Borderless / Windowed Fullscreen instead — visually identical, and the overlay stays on top.
