Hi, I'm Kat or Duchess

I'm an Australian data miner who writes farming, event, and food buff guides for Fallout 76.

I believe that all knowledge and information should be free which is why my guides will never be locked behind a paywall. However, running a website and photo and video editing software does not come cheaply.

So, If you found my guides useful, please consider buying me a ko-fi (coffee) using the link below.

All monies go towards the tools for writing my guides and maybe for an actual cup of coffee or 3 ;)

Alternatively, share my guides with your fellow vault dwellers and help them to survive the wasteland.
