Nah. It’s a LOT over the top ;)
Iona and Jordis are pretty cool too. But LLydia seems to be the most brutal fighter of the bunch. They are all supposed to be the same stats (Housecarls) byt Lydia always seems to put her steel boot in more arse than the rest...
I gotta be careful what weapons I have Lydia hold on to, because one time I gave her a whole bunch of staffs and she was blowing the whole place up with fireballs. I've even seen her use random magic attacks, maybe some scrolls I had her hold on to. Sometimes I wonder if she picks up items, because occasionally I look at her inventory and can't remember giving her all these scrolls and ingredients.
