Dracula's Castle is full of hidden passages, secret rooms, and concealed items. Many of these require specific Ability Souls to access, encouraging backtracking and thorough exploration.

Key Hidden Areas to Look For:
- Breakable Walls: Many walls can be broken by attacking them repeatedly. Look for suspicious-looking blocks or areas that seem to lead nowhere.
- Floor/Ceiling Gaps: Use the Slide (Gargoyle Soul) to access narrow horizontal gaps and the Double Jump (Giant Bat Soul) to reach high vertical openings.
- Water Areas: The Undine Soul (Ability) allows you to walk on water, revealing paths previously inaccessible.
- Flying/Floating: Later in the game, the Bat Soul (Guardian) allows you to transform into a bat, granting full aerial control and access to even more hidden areas.
Always check your map for unexplored sections. If a room has an unrevealed corner or a path that seems to end abruptly, there's likely a secret there. These hidden areas often contain powerful weapons, armor, or rare items.
