aion2calc
Plan your AION 2 build, learn from your fights, and plan raids on a visual timelapse map — free and open source.
The raid planner runs right here in your browser — no install. The desktop app adds build optimization, gear advice and combat-log analysis.
Build & rotation optimizer
Best skills, stigmas, Daevanion, arcana, stat priority, a copy-paste macro and a priority rotation for any class — in the desktop app.
Combat-log analyzer
Paste an AbyssLogs link for an AionFlex-style breakdown: per-skill share, crit/double/perfect, cooldown use, timeline and idle time, compared with the optimum.
Raid & boss planner
Drop player, enemy, marker and AoE tokens on a map, scrub a timelapse slider and drag each to plan movement over time. Lay out party buffs; overlay a real fight.
The desktop app
Download
Windows, macOS and Linux. No Python and no command line. The app follows your computer's light or dark mode. Builds are unsigned, so the first launch may need one extra click.
