I started a no crafting warrior build, yes, I know, I keep doing new builds, and kind got stuck with him. If I were playing a stealth build, I'd hate him, but for a warrior, he's working out great. I am loathe to give him back to Clavicus Vile and am ignoring that quest. Would love to pick up another dog and have some fun. The chaos damage is too funny. I'm a dog owner, I don't mind as much. Thinking at first Vigilance, but then moving on to that amazing wolf from Wyrmstooth. I think Barbas allows for a second creature follower as he's quest-related. Barbas also works with Serana, unlike other human followers.
Has anyone tried taking Barbas to Solstheim? I know Faelor (the Wyrmstooth wolf), was able to go.
