Actually it is my character, Zoe, who has reached level 80 and met the ebony warrior. Hooray! Now she is getting ready to face him. She is planning on taking her dragonbone bow, mace, spellbreaker shield and probably wearing light max armour cap armour. Her gear will have fire enchants.
What follower would you suggest she take with her? It could be any in the game including DLCs.
Any suggestions on what, if any thralls she could bring (she has conjuration twin souls)?
Plus any other suggestions?

Well...personally I wouldnt bring any thralls. It's a duel, i would just fight him one on one.
