I'm a gnomish Wizard in Nethack 3.6.0.
In Minetown, a werewolf attacked me and conveyed lycanthropy to me. I was wearing my starting cloak of magic resistance when transformed to a wolf, dropping my weapons and armors on the ground. To get rid of lycanthropy, I rushed to the temple(luckily enough, it's co-aligned), sacrificed some wolf corpses and prayed to my god. By the time I went back and tried to equip myself with those dropped items, my cloak of magic resistance has gone!
I thought it might be stolen or picked up by a random monster nearby, so I killed all monster on that level except shopkeepers and the priest(I'm sure there are no monsters left, because I have intrinsic telepathy), but I still couldn't find the cloak.
Then I thought, may be I've got intrinsic magic resistance? To (dis)prove that, I stripped myself naked and zapped myself with a force bolt spell and a magic missile spell. The only message I received was "boing", and I didn't lose any Hp, so it seems that my guess is proved.
However, as far as I know, magic resistance isn't an intrinsic. Is it true that I got intrinsic magic resistance through a hidden mechanism, simply because I wore a cloak of magic resistance when being transformed to a wolf?
PS: Although I have magic resistance now, I still want to get my cloak back, for I've already enchanted it. Any ideas about how to find it?
