Is there a guide for All Dungeons Swordless?

There are no existing tutorials for the entire route, but there are a few resources:

Blank has a number of videos on his youtube channel that are helpful, namely:

Here's a doc with the route: https://docs.google.com/spreadsheets/d/1HZGpb5prw131uMz2FxJxUmtvyfQvDDafVQyv5rG-m6E/pubhtml?gid=1469878830&single=true

superSKUJ also has several videos which cover a variety of glitches used throughout the run: https://www.youtube.com/playlist?list=PLPsUbwi58oG_hjrgq1wpYmM3JMEn9b8R8

Apart from that, I would just advise watching some of the top runs on the leaderboard.

Hope this helps!
