I had a voratun armor drop off an adventurer party (the first one I met as a level 5 alchemist). I could not use it for anything of course(it was a trash green anyway) since it had a 44 strength requirement but it just struck me as very odd. The only way it makes sense is that it was such a bad random roll low that it became high

Now in the old forest I found both a level 30 naga myrmidon and a level 30 elite vampire. Both just walking around and on two separate levels (1st and fourth). I am very curious how they spawned. (I was 8th level btw when I first entered to clear 1st level and 15th when I came back to clear down to the lake). Neither came from a vault or something like a graveyard.
