Oh… I’m not sure but I had a really hard time beating him… maybe I just sucked.

Just before you fight Alduin there’s some dude you have to beat up if I remember correctly, I think Tsun guarding the bridge to the Hall of Valor? I remember him just one-shotting me so I had to crawl into some terrain he couldn’t hit me from and I just very slowly killed him with a bow and arrow when I had absolutely no proficiency in archery.
