4. Hyperdimension Neptunia Bestiary

This is the bestiary list from the in-game tome, which shows most of the monsters in the game. Some monsters do not appear in the bestiary (and do not count for bestiary completion) so they aren't shown here either. I've added the locations of each monster so you can track down any you missed, along with noting which ones are missable. For regular monsters, I list both the story related dungeons and timed dungeons they appear in. You cannot go back to story dungeons, so if you're missing a monster, check one of the timed dungeons listed. Story bosses are listed merely as story bosses, since they cannot be missed. Bosses that appear in timed dungeons show the quest they are found in, and the landmass the quest occurs on.

The good news is that in the process of finishing all the side dungeons and doing the story, you'll get the vast majority of these. After doing everything I only had a few monsters that took any effort to track down. I'll note here as well that some monsters seem to show up more often when using monster call, and some show up more often during random encounters, so if a monster isn't showing up, try both. You can also try getting into encounters in dead ends to see if that helps. It did once or twice for me.

Due to the nature of the bestiary, there'll be some minor spoilers here due to boss names. Bear in mind the missable monsters are highlighted in the actual walkthrough, so you can check this after you finish the story to avoid spoilers of any kind.
