The Oarsmen Nornir Chest Puzzle Solution
The chest is at the location shown in the pictures below. To unlock the chest, you need to hit three seals in quick succession.
One of the seals is behind a closed gate on the right side of the chest. So first, you will need to open this gate. To do that, climb up the wall behind the chest as shown in the picture below. Then go straight ahead and climb up the golden chain on the right side. Then jump down to the other side. There you will have to move a giant chain as shown in the second picture below. This will reveal a staircase on the left side. Climb down the stairs and then you will be able to open the gate from the other side.
Now to unlock the chest, you will have to hit three seals in quick succession. Stand at the location as shown in the picture below. From here you will be able to see all three seals. Hit Seal #1, which is on the left side of the chest. Then turn left and hit Seal #2. After that hit Seal #3, which is on the right side of the chest. Now open the chest to get an Idunn Apple.
