About this tool

This is a rebuilt offline version of the MUA3 Heroes and Teams tool originally created by u/ArcOfSpades at dnawoods.com/mua/ (now offline). The original was built with Python + Flask; this version runs entirely in the browser with no server required.

Data status: Team bonus data is complete (all 52 heroes). Individual stats (STR/VIT/MAS/RES/DUR/ENE) recovered for 28 heroes from a July 2025 mirror. Stats marked no data are from the 24 heroes missing from the mirror.

Hosting options: This file runs locally in any browser. To share it online for free, upload to GitHub Pages, Netlify, or Vercel.
