Once inside the tower, follow the ramp down first to find a Phoenix Feather.
Make your way up this time then exit the tower. Head to the right first to find two red chests, then continue to the left and take out the eggs/ hatchlings. Proceed past the ladder and you'll find another red chest and a Gorgon Eye chest.
Climb the ladder this time and defeat the chimera. Once dealt with, pull the crank ahead to activate a series of machines that will move the red python contraption. Enter the hole on the red python this time.
Once inside, go up to the right to find a red chest offscreen. Open the health chest nearby if needed then continue down the ramp to slide. Jump across the holes until you reach the section full of eggs and a couple of shielded minotaurs. You can grab and remove their shields so you can use it as a melee weapon. Clear the entire area for extra red orbs as well.
Destroy a few more eggs blocking an opening to reveal a red chest. Head to the opening overhead to get outside. Continue to the left until you find some glowing green metal protrusions. Use it to swing to the next part of the red mechanical python.
After reaching the other part of the red python, go up the ramp to the left first to find an hole in the brown python's side where a red chest and Gorgon Eye is found.
Continue along the path until you reach another hole with a gate below. This will start the next chapter.
