I turned in the contract for wailing banshee finally, as I got tired of my previous merc. I noticed a few days later when I used sense the dead (to quickly point me to the next undead mob since I had to hunt them for a quest) that it pointed me to the merc! Technically, I get it. It's undead. Makes sense. But so is my pet, and my pet doesn't interfere with sense the dead. Can mercs be marked as not undead so our lowly level 1 spell is still useful? Thanks!
