From the hidden area where you found Dracula's Ring (after using the Red Crystal), head left. You will eventually reach the entrance to Dracula's Castle. It's a formidable structure, clearly marking the end of your journey.
- Preparation: Before entering, ensure you have a good supply of Laurels and your strongest whip (Flame Whip is highly recommended). The castle is a gauntlet of the game's toughest enemies.
- Castle Layout: Dracula's Castle is a linear, upward climb. You'll face a relentless assault of powerful enemies like Red Skeletons, Axe Knights, and more. Use your Sacred Flame sub-weapon strategically to clear paths.
- Hidden Passages: There are no major puzzles or hidden items in the castle itself; it's a straightforward path to the top. Focus on survival and conserving your health.
The castle is designed to test your skills and endurance. Don't rush, and be prepared for a difficult ascent.
