h3sed

h3sed is a Heroes3 Savegame Editor, written in Python.

It opens savegame files from Heroes of Might and Magic III, allowing to see an overview of all heroes, and edit any and all hero attributes:

• primary skills, like Attack
• other primary attributes, like level, experience points, spell points etc
• war machines, like Ballista
• secondary skills, like Logistics (more than 8 skills can be added)
• artifacts, like Boots of Speed, both worn and inventory items
• spells, like Slow
• army creatures, like Golden Dragons

Attributes can be copied from one hero and pasted to another.

Hero data can be exported as HTML or spreadsheet.

Supports savegames from Shadow of Death and Horn of the Abyss.

Usage

Navigate the file view to Heroes3 games-folder and open a savegame file to edit, or drag and drop a savegame file onto the program window.

Choose a hero to modify, change attributes to your liking, and save the file. Changes will be available in Heroes3 after loading the changed savegame.

Attributes from one hero can be copied to clipboard as text, and pasted onto another hero, overwriting their data.

A timestamped daily backup copy is automatically created of the savegame file, one per day.

Warning: as Heroes3 savefile format is not publicly known, loaded data and saved results may be invalid and cause problems in game. This program is based on unofficial information gathered from observation and online forums.
