Ran through this today, and a bit surprised to find a reference to the Rabenkunst spell list in the lower level, when this product doesn’t yet exist.
Also, I couldn’t find any precursor beast generator in Bernpyle Issue 1… I eventually found the link in the description here, but in the actual dungeon it references Issue 1, and as I’d printed the dungeon off, I wasted a bit of time trying to find it there.
You should probably remove these references. Otherwise a fun little dungeon crawl!
