Ys IX: Monstrum Nox Mini-100% Guide; Quests, Character Notes, Grimoires, Gifts, Recipes & Chests

This is pretty random and out of nowhere, but while I was cleaning my PC’s files, I stumbled upon a mini 100% guide I made for Ys IX: Monstrum Nox when it initially launched in the West last year. I primarily wrote it for an Ys-centric Discord server, but I never made it an article for some reason, so here it is.

This guide lists all quests, character notes, recipes, gifts, grimoires, and some minor tidbits. Regarding Blue Petals, the Chinese website Gamersky edited a custom map showing each petal’s location, which is inestimably helpful. Moreover, I took screenshots of every map in the game to depict each treasure chest. Lastly, when the game launched, I published a video sharing each hidden location in Balduq City. I’ve linked this video below as well.

If there’s anything notable missing throughout this guide, please let me know. As a tip, I recommend checking in on every shop at the start of each chapter due to stock changes.

Treasure Chests and Map Completion in the Prison do not contribute towards overall completion. Monsters do count, however.

Note regarding affinity – I have not included Maximum Affinity events in this guide because they are all pointed out on the map during Chapter 8 and the Finale via heart icons. You must do these to get character notes, but you can’t really miss these unless you actively avoid them. 

Always fill the Nox gauge to 100 twice each chapter for both the required and optional Nox.
