You can recreate your in-game gear setup exactly as it is to calculate average damage and stats, or use the planner to theorycraft builds, then save and share them.
The site also includes timers for in-game events and content, see the landing page for details on the guild tracker.
The tracker centralizes events, builds, attendance, and formations among other things.
It’s currently the only purpose built guild management tool for the game, with deep Discord integration.
