Main Walkthrough

Being an RPG, The Legend of Legacy has monsters. Lots of monsters. It has so many monsters, in fact, that you probably won't see all of them in a single play-through of the game. Every time you kill a monster - not just encounter, but kill, as far as I know - it will be recorded in your Encyclopedia; you can then use this document to determine how many monsters you have left to encounter.

Or you can use this list. Your choice.

I'm still working on this list of enemies in The Legend of Legacy, so it'll be edited as I go along. Bear in mind while playing that some of the rarer enemies may not appear until you're on a New Game Plus. (Or you'll have to look for a really really long time to get them to come out and play during your first game.)
