My 2nd Armored Wyvern collection yielded: 5 Silver, 3 Iron, 2 Earth Wisp, 1 Mithril and 1 Wyvern Milk.

So far my Baby Troll has dropped: Glimmerdust, Troll Horn, Bone, Creep Tooth. I've collected a few times and it's always been 2 items, usually Glimmerdust and a monster item or a Troll Horn and a monster item.
