I've found as low as level 10 item there mate. Plus I've got a message from someone who got THE ring in VotA ;-)
EDIT: I've made a couple of runs through VotA checking the random rings and you may be onto something. I still believe LS can drop in VotA, but it actualy can be harder to obtain there. I'll be switching my runs to VotA (for quick 5 stacks) and then full clear up to Maghda, maybe that will help a bit.
