Seems like you haven't met Cicero yet. ^.^Anyone try to "sneak" while using a companion? Just saying...
Hi Guys
I use Lydia mainly as a mule, but also so she fills up all of my soul gems. I have given her a war hammer with soul trap on, and as long as its a "white" soul she traps the soul. The only problem is that she will fill any soul gems with petty souls.
