Tomb of Eteokles
Tomb location: Attika.
Enter the tomb, continue forward, and smash the wall. Continue along the corridor and watch out for traps and snakes.
When you are inside the chamber with the sarcophagus go to another passage and continue downwards. You will reach a room with two wooden shelves you can move. Kill the snakes and pull the first one, to reveal a crack.
Now move the second shelf inside the crack to reveal a passage. Continue forward – watch out for traps and snakes.
Open the chest and discover the Ancient Stela.
Move another shelf and take the shortcut to reach the exit – you have successfully completed another tomb.
