First, you have to make your way to the Tetsu’s Rise which is near the Sorcerer’s Isle in the Liurnia Region of the Elden Ring. You have to keep on going up all the way north in Liurnia to reach the Tetsu’s Rise. It is located on a small island where is also Sorcerer’s Isle.
Once, you’ve reached the Testu’s rise which is a Tower, you will see that the main door is sealed by a blue magical aura. There is a statue beside the sealed door which has a book in his hands. You need to use the book and it will say Seek Three wise Beasts.
To solve the puzzle to break the blue magical seals you have to hit three turtles that are spawned in the area.
For the first turtle, you need to go left from the main door and where the statue is, you need to go a bit to the left and you’ll see a rocky cliff. There is a turtle spawned there on the cliff rocks, you need to go and hit the turtle with your sword or if you have a bow then hit him with your bow. This will complete the first Wise Beast.
For the second turtle, you need to go straight right from where you found the first turtle. Also, you can find the second turtle behind the Titsu’s rise Tower from the main door. You will find this turtle on a tree. So, you’ll have to be careful when looking for this turtle. You can hit the turtle with the bow. This will complete the second Wise Beast.
For the last turtle, you need to go right from the main sealed door and where is the statue located. You need to go straight right and go to the edge of the rocky cliff. You will find the final Turtle below there. You can go down and hit the turtle with your sword or you can hit him standing on the cliff with your bow. This will complete the third Wise Beast.
After you’ve hit all three Turtles, the Wise Beasts. The main sealed door will now be broken and you can now head into the tower.
You need to go inside the tower from the opened door and there is a ladder there in front. You need to climb all the way up the ladder and when you reach up the ladder there is a staircase going up outside the tower, you need to go to the top of the Tower. When you reach the top room of the tower, there is a chest there you need to open the chest and pick up the items. You’ll get the Memory Stone from the chest.
