I’ve been looking through the boards and sites and can’t find a full list of Monstrology Monsters per world. I’ve gone to Wizard101Central as a starting place and looked at all of the monsters they have listed by location/world and put the ones they list with Monstrology Information into a list. I’m hoping that we can crowdsource what’s missing.
In Azteca, the game identifies 41, of which I’ve found 39.
