The video is here.
It’s 2 hours and 16 minutes long (more than an hour shorter than the Deadmines!). Each notable encounter has a corresponding timestamp to jump to.
It hopefully deals in a great detail with each and every mob, pull, boss, quest and all the other little things inside Shadowfang Keep from solo standpoint, including those low-level class quests. It also includes a non-exploitative strategy to circumvent Arugal’s MC (which is known to reset the encounter if you go at him solo).
There is no voiceover, facecams or persistent music, but there are heaps of hopefully rather easy-to-read text.
Reddit thread for those who are interested.
My previous Deadmines thread (now closed).
Cheers, and keep overcoming.
