Rover Mansion – Dracula's Heart

From outside Berkeley Mansion, head right along the upper right path until you reach the caves.

In the caves, continue right and enter the upper-right exit to a new cave area.

Follow the path downwards until you hit the ground floor.

Stop and destroy the blocks to the left to open a path.

Head to the very end of this path and destroy the wall to uncover the Sacred Flame.

Continue right to the next screen. Save your game if possible.

Jump onto the blue rock and use a Holy Water to break the ground ahead, revealing Hint Book 5/13: "To replenish earth, kneel by the lake with the Blue Crystal."

Continue right, battling Spiders and Skeletons, until you reach the town of Aljiba.

Enter the first door in Aljiba, use Holy Water to break the floor near the middle, and head down.

Talk to the man at the bottom and buy Garlic for 50 Hearts (you receive two cloves).

Exit and enter the next door, use Holy Water to break the floor, and head down to the middle floor.

Head left on the middle floor and use Holy Water to find Hint Book 6/13: "An old gypsy holds a Diamond in front of Deborah Cliff."

Continue to the bottom, then right to speak with an old woman about Dracula's Eyeball.

Exit the house and head to the right side of town, then upwards.

Enter the house, break the floor, and head all the way to the bottom and right to find a trader.

Buy Laurels from the trader (you receive two).

Exit the house and go to the top of the town. Find the man in the grey cloak (likely at the far left) and agree to exchange your White Crystal for his Blue Crystal.

Exit Aljiba to the right, entering Camilla's Cemetery.

Use a clove of Garlic on the ground to summon a trader who will give you the Silver Knife.

Head back into Aljiba and travel all the way left, leaving town the way you came.

Head west to the next screen, killing Spiders and Skeletons.

Take the stairs down to the bottom and continue right into the cave.
