Seeing as completing a full map is a regular Ys goal, Monstrum Nox is no different. However, it’s not as simple as exploring everywhere you are introduced to, Balduq carries a few secrets in the form of hidden areas. Fret not, adventurer, this guide is for the locations of all the hidden areas in Ys IX Monstrum Nox.
All Hidden Area Locations in Ys IX Monstrum Nox
These won’t be in any particular order, as there are factors such as character and progression details to keep you from several of these, but all are available once you have access to every district of Balduq.
Waterway Vault Hidden Area
Right in the middle of the Main Gates area is that waterway you might have jumped into occasionally to fight the Lemures from the black pillars. At the northern end will be this grate. You will need to be able to use Renegade’s gift of Shadow Dive to get under this grate and into the Waterway Vault.
