Thank you for sharing this. For some reason I ignored that cave from the start and now I am lvl 42.
Having switched the difficulty on master recently and after reading all the above comments I decided to go prepared, so I took with me a bunch of resist potions, a few damage Health (50 points) poisons, Mjorn the Lioness (wife) and also used the shout that brings a dead female warrior from Sovngarde. So the fight was feeling slightly hard as I had to withdraw weapon and heal behind a pillar at some point.
I must admit that if I had not read your comments, I would walk to a certain death, specially after getting all cocky for killing those Chaurus thingies.
Mjorn the Lioness? You should really know her name, she is your wife! It's Mjoll lol I could just picture Ysolda if I came home and called her Yosalda lol
