When you come to the section of Sharline's game with the statue that only has a pair of feet, you will need to remove all of your armor and weapons except for your boots to progress through to the next section. Once you have removed the appropriate items, check out the statue and you will be transported to another area.

In this area is another statue puzzle, the Archer. Equip your Solta Bow and unequip all your armor except for a pair of red boots and stand on the platform across from the Archer. A room will open up with a treasure chest containing the Statue Torso.

Return to the original room and attach the torso. Then, remove all your armor and weapons again except for your boots and body armor. Access the statue again and be transported to yet another area.

When you get the Statue Head from this new section, head back to the original room once again and repeat the process to be transported to the final area.
