I have all of the 5e fantasy modules and this is the third I've run. Like the others it takes just a bit longer than one session (if you're playing only three or four hours). I fit this story into Faerun (put it in the Giant's Run mountains, changed the evil dwarf god to Abatthor) as a way to start a Faerun campaign. I nerfed the hit points a bit for some of the villains to make this useable with first level characters.
I like the idea of exhaustian levels in addition to normal damage.
All around good adventure.
