Tsurumi Stone Slates

Table of Contents


Scattered around Tsurumi Island, there are seven Stone Slates you can find that unlock an achievement and reward you with Luxurious Chests. The Stone Slates are not part of a World Quest in the area but require you to advance the main Quest Series of the island to find them.

Finding and placing all seven stones, unlocks the “Seven Letters” Achievement and spawns two Luxurious Chests for you to loot!


To be able to start finding the Stone Slates you must complete the “A Particularly Particular Author” World Quest and start its second part “Octave of the Maushiro” Quest.

While doing this second part quest the “Peculiar Pinion” gadget will activate and allow you to interact with the Thunderbird statues around the area. This is necessary to reveal puzzles and collect the Stone Slates.

However in order to get the “Peculiar Pinion” in your possession, you will have to finish the “Seirai Stormchacers” World Quest in Seirai Island first! So there are a few requirements you must meet before you can start looking for the Slates!
