This section is a maze of ancient statues and narrow corridors. You'll face Medusa Heads in greater numbers, often in conjunction with other enemies. New enemies include Spear Knights, who have shields that block frontal attacks; you'll need to hit them from behind or use a sub-weapon that bypasses their shield (like the Axe or Holy Water). There are also Living Statues that animate when you get close; they are slow but powerful. The platforming becomes more precise, with moving platforms and disappearing blocks. Take your time and observe the patterns before committing to a jump. A well-placed Holy Water can clear paths of ground enemies, making navigation safer. Look for a hidden Meat item behind a breakable wall before the boss area to ensure you're at full health.
