Irminsul is a utility to extract data from Genshin Impact and export it for use with Genshin Optimizer and web sites, applications, and utilities that use the GOOD data format.

Irminsul utilizes packet capture instead of the common optical character recognition (OCR) that other scanners use. This allows it to be much quicker in exchange for:

1. Needing to run with CAP_NET_RAW/admin/root privileges (for the packet capture)
2. Needing to be run when Genshin starts to observe the handshake with the server.

To use the pcap capture backend, make sure to install a Pcap library (Npcap/WinPcap on Windows, libpcap on Linux).

Irminsul accepts a handful of command line options for advanced use cases:

• --capture-backend <pktmon|pcap> (shorthand -b): chooses which capture backend to use. On Windows both pktmon (default) and pcap are available. On other platforms only pcap is available.
• --no-admin: skips the automatic elevation prompt. This can be useful when you prefer to launch the application without requesting higher privileges up front.

In it's current state Irminsul supports:

• Incredibly fast capture of all Genshin Optimizer supported data
  • Artifacts including "unactivated" rolls and reporting of initial values for rolls
  • Weapons
  • Materials
  • Characters
• Simple, clean UI
• Export settings to filter which data gets exported
• Exports data either to the clipboard or saved to a file

Planned features include:

• Achievement export
• Wish history export
• Real time data updates while game is running

• Docs
• Discord

Irminsul is built upon the work of many others.

• PJK136 whose work on a fork of stardb-exporter provided the main inspiration for Irminsul's development.
• juliuskreutz whose stardb-exporter provided the foundation for PJK136's work as well as providing some examples for how to wrangle egui.
• hashblen whose auto-artifactarioum is used to interpret the network packets from Genshin.
• IceDynamix whose work on Honkai Star Rail network scanning is at the root of many of the Genshin and HSR network scanning utilities.
• emmachase who wrote the packet capture library pktmon which Irminsul uses to allow packet capture without having to install a npcap driver as well as their contributions to some of the above projects.
• Genshin Optimizer without which there would be no point in exporting data.
• Inventory Kamera which was my introduction into artifact and character scanning and whose discord provided a collaboration environment that spawned Irminsul.
