Ys Origin/Monsters

The monster journal can be accessed from the menu and is shared with all playthroughs. Each entry requires defeating the monster multiple times to fill in all of the stats. Two of the monsters, Hubamobrum (31) and Zelkaron (40), will not respawn once you defeat them. For Hubamobrum, you can defeat one or two of the group, leave the area, and come back for them to respawn. For Zelkaron, you can use the same strategy or you can continuously fight them as long as you don't have the Silver Chimes equipped. Alternatively, you can later fight both monsters in Arena Mode. For the Cryptozoologist achievement, you need to complete entries 1 - 68.
