A lot of monsters have "multiple" drops, most clue drops are seperate to the main drops, then things such as charms added to this. With mith dragons pretty much every drop had atleast two boxes to check, sometimes 3 as they can drop a shark with their drop too. Maximum possible is Mith dragons I think - Dragon Bones, Mith Bars, clue, Normal Drop, Shark, Visage. Or KBD Dragon Bones, Dragonhide, clue, normal drop, visage and kbd head.
