So last night my brother and I decided to go kill a few bosses in the Twilight Forest. We started with a Lich, then we killed a Naga, and then a Ur-Ghast. Somewhere along the way we both lost our helmets. My brother had an ultimate solar helmet and I had a Force Armor Helmet. We noticed the loss after fighting the Ur-Ghast, and were wondering if that had anything to do with the loss. Does the Ur-Ghast eat helmets or something?
