I'm about to finish the Nashkel mines and I'm wondering if I should take Xan instead of Dynaheir. I have a good-aligned party made of me (fighter), Imoen (NOT dual-classed), Ajantis, Kivan, Branwen and Dynaheir. The fact that Dynaheir doesn't have access to sleep or blindness is bothering me. Should I replace her with Xan? What do you guys think? I'm open to other options as well but I prefer not to have evil characters in my party.
