Location of Ainigmata Ostraka: Attain the ruins of Spring of Piera Situated in the Middle Section of Elis on the Forgotten Swamps.

As soon as you’ve found yourself at the ruins, take an interest in the entry to the cave displayed in picture 2. It’s over the primary part of the ruins and the eagle will be able to help you to locate it.

After entering the cave, hop into the water. You need to swim through a huge section under water.

Reach the last area of the cave, then take an interest in the passage shown in picture 1. You will reach a new area with two grips (one of which is an alpha male). Kill them.

Investigate the lair of killed bears. The tablet is in the place shown in the picture.

Solving the riddle: Exit the cave and head towards the Valley of Olympia. You don’t have to visit the hippodrome from the hint from the ostraka. Instead, head straight to the hill situated northeast of the Olympic village as shown in the picture.

The purpose of the journey is the statue of Kronos located on a hill.

Climb on the statue. An interactive area can be found on the right wing of the statue.
