Unlock Requirement – How to Farm 10 Onmyo Mages
This mission has a unique unlock requirement. You must defeat 10 Onmyo Mages. Two of them are found close together in The Sun Sets on Mount Tenno. After the 2nd Shrine in that mission (the one after going through the flooded fields), there will be two big crystals you can destroy. In the cave below those two crystals are two of the Onmyo Mages. You can tell they are mages because they use magic buffs on themselves and shoot magic to debuff you, but they don’t do much melee damage without buffs. Defeat these two, go to a Shrine to respawn them and repeat.
Where’s the key?
Your objective is basically right in front you. It is the building next to where Saika fights some samurai. The problem is: you need a key.
Head into the caves, up the ladder and follow the path until you find a hole in the floor where you can drop down to a room with some mages in it. The key you need is in the chest there but once you open the chest a bunch of Yokai will spawn which you have to kill, or you can simply die and respawn at the Shrine instead if you don’t feel like fighting them. The key will still be in your inventory.
With the key, open the door to the building at the start of the mission and destroy the crystal there for the mission to succeed.
This finishes The Aberrant Mage side mission in Nioh 2.
