From what I've dealt with, with HOURS of trying this challenge... There's the Foul Lair - with chickens & a pig, full of treasure The Veiled Treasure dungeon full of chests Vile Swarms Shower of Gold Ancient Urn Resplendent Chest A Yellow Mob (mine were the big golem like things) A Puple Mob (again, mine were the big golem things) Still waiting on the diseased bodies, and the final one, whatever that is... A mob of skeletons? --- Wait, sorry - my mistake... A few minutes after posting, I actually had the ancient artifact spawn (probably) about 8 out of 10 attempts... Unfortunately, only 1 of them was one of the 3 I needed.. So its as above, however, there is a resplendant chest, a standard chest, an urn, gold, the vile swarms, the golem like monster things, the 2 vaults (veiled treasure and fowl lair) and I assume the final 2 are the skeletons and diseased bodies... If only I got those 2 instead of the swarms - seem to get those almost every time now...
