Dracula's Castle and its paintings are riddled with hidden rooms and breakable walls, often concealing valuable items, relics, or even entire new pathways. Look for suspicious-looking walls that might have a slightly different texture or cracks. Use Jonathan's whip or Charlotte's offensive spells to hit every wall you suspect. Some hidden rooms are only accessible by using specific relics like the 'High Jump' or 'Owl' sub-weapon. Always check dead ends on your map, as they often hide secrets. A good rule of thumb is to hit every wall that doesn't immediately lead to another room, especially in areas where the map shows an empty space adjacent to a wall. The 'Eye of Truth' relic, once found, will reveal hidden breakable walls on your map.
