Chapter
Dracula's Castle walkthrough
The wings we can name
Public chapter coverage is thinner here than in Paris, so this page is a wing map, not a fake turn-by-turn. The Main Hall holds Brauner's Atelier, the route toward Alucard's Tower, and the Archives. The Library's Observatory is Carmilla. The Clock Tower has Talos at the Throne of the Builder and the real Isaac at the Heart of the Clock.
Notre-Dame hangs off the Main Hall painting and holds Death, the Brittle King, the Four Virtues, and the Doppelganger. The Master's Quarters are Dracula, in two phases. If the Four Virtues and The Self are unfinished, the sources say you are locked to the normal or bad ending.
Spoiler gate for the last room
The final fight's phase details stay on the endings page, behind the condition table, so a castle walk does not spoil the last choice. What belongs here is the approach: Isaac at the top of the clock, then the Master's Quarters. A room-by-room IGN chapter for the castle interior was not in the set I could read, and I am not filling the gaps with guesses.
- Ability checks inside the castle: Smash for floors, Aerial Rush for Durandal and the painting, double jump for the later Notre-Dame seal.
- Optional: Isaac's phantom on the Castle Drawbridge does not drop a card.
What I ran into
I wanted a corridor list. The sources gave me boss rooms and wing names, then stopped. Writing 'go left at the third chandelier' would have been fiction, so the page stays at the wing level and points at the map pages for the sub-areas that are actually named.
Questions
Where is the final boss?
Dracula is in the Master's Quarters, after Isaac at the Heart of the Clock. The fight has two phases.
Can I finish the game before Notre-Dame?
You can reach an ending, but the good ending needs the Four Virtues and The Self, and Notre-Dame is where that work happens.
