So I was trying to get to Hrogthar from Whiterun (Go to Iverstead, look for giant stairs, follow them), and I ran into a wispmother. I had a housecarl with me, but still died when the Wispmother spawned two other Wispmothers to join her.
I'm a level 9 Wood elf specializing in Archery, One-handed Weapons, and Sneaking. What do I need to do to beat her? Spells? (Which ones?) Regular weapons?
