How to Find Ancient Sentinel Cores in Octopath Traveler II

There are a couple of known places where you can locate this rare material. The first place is during Partitios Chapter 2 at the Roque Factory. If you have passed this chapter and still need this material, it is okay, as the game lets you go back whenever you want to do a quick farming session.

The second place known to contain Ancient Sentinel Cores is the Wandering Woods by the Nameless Village. That said, players have reported that the first location has a higher chance of spawning such material.

Ancient Sentinel Cores are required for the “Research Materials, Part 1.” This side quest is the first step of obtaining an additional Scholar License, and the first step requires the player to turn in five Ancient Sentinel Cores.
