Simple editor for the savegame file format used by Eidolon from Icewatergames.

Project Description

Early in my playing of Eidolon, I somehow missed my chance to find the fishing pole and continually had trouble finding enough food to survive as a result. This is the tool I wrote to avoid having to trek all the way across the world to find that fishing pole.


From any environment where pip is available:

pip install eidolon-savegame-editor

Or, from a clone of this repository:

pip install -e .


eidolon_savegame_editor /path/to/savegame COMMAND

But where’s my savegame?

OS Path
OSX ~/Library/Application Support/Steam/SteamApps/common/Eidolon/
Windows C:\UDK\EIDOLON\Binaries\Win32\SaveData.bin



Resets your hunger to zero.

add_items ITEM COUNT

Adds items to your inventory.

Options for ITEM include:

  • Mushrooms
  • Tinder
  • CookedFish
  • Honey

or any other item in your inventory; use the key _items in show_properties to see what’s in your inventory currently.

Note: If the item name you enter is not something that exists in Eidolon, it will be ignored by the game, but will stay in your savegame file forever.

add_tool TOOL

Adds a tool to your inventory.

Options for TOOL include:

  • nocs
  • rod
  • compass
  • bow


Enumerates properties found in the savegame file.


This may destroy your savegame! Make a backup if you don’t trust this script.
