Gorgon.

Begin in the Marble Gallery, passing through initial empty rooms.

Drop down through red platforms, avoiding spike traps and new enemies like Jack O’ Bones and Nova Skeletons.

Take the path to the right. Continue through rooms with Skeleton duos and impale traps until you reach a door to the right of a skeleton and traps.

The next room is empty.

Enter the room outside the clock room. This area features two Guardians and a Blade. The Guardian is a strong, Level 60 enemy that grants 1500 experience, making it ideal for grinding before Level 60. For now, skip the Guardian.

Enter the clock room. Drop down the center opening to find all sub-weapons in stasis. Break the glass to acquire them. The knife sub-weapon remains a good choice. To the far left of the sub-weapon stasis is a Heart Max Up, and to the far right is a Life Max Up.

Exit this section and use the door on the right to continue in the Marble Gallery.

The room to the right of the clock room mirrors the room before it, but contains two Guardians and a Gurkha instead of a Blade.

Proceed from the room with the Guardian. The next room contains Skeletons and a Gorgon. The Gorgon is a slow, bull-type enemy that breathes petrifying breath; maintain distance to avoid it. Defeat the Gorgons and Skeletons on the left and right, then proceed through the door on the right. You can fly up to the ceiling to access another castle area, but we will skip this for now.

The room after the Gorgons is quiet, featuring only large skeleton heads that fly up and down.
