Companion overlay
The whole HeavenlyForge database on top of your game, without leaving the match.
The overlay is a small window that sits on top of Heroes of Might and Magic: Olden Era. Look up a unit, hero, spell or artifact, calculate damage and report your games, all without minimizing the game.
Free. Windows 10 and 11. About 80 MB.
What it does
Live search
The whole encyclopedia (units, heroes, spells, artifacts, laws, buildings) at your fingertips, in the game's 16 languages.
Damage calculator
The same exhaustive engine as the site: build a character on the fly and compare damage during the match.
Match reporting
Report your games in a few clicks to feed the community tier lists.
Always up to date
The data follows every patch automatically, and the overlay updates itself, with nothing to reinstall.
How it works
Once installed, the overlay starts with Windows and stays out of the way in the system tray. It appears on its own over the game when you launch Olden Era, and tucks away when you close it.
On first install, Windows may show a warning (unsigned app): click "More info" then "Run anyway".
