| Tool | Purpose | |------|---------| | Hero Editor | GUI editor for stats/skills/items | | ATMA / GoMule | Stash management and item transfer | | d2s-save-editor (Python) | Command-line parsing and validation | | d2edit (hex+struct) | Low-level binary inspection |

A .d2s file is a binary file encapsulating a character’s entire persistent state relevant to gameplay and display. Key logical components:

For v1.10+, synergies are not stored; they are computed on the fly from skill levels. The save file only records the actual assigned hard points.
