How to find and collect all scattered royal crown jewels to open the secret vault door in the castle basement

Welcome, fellow adventurers and completionists, to the definitive master guide for thegamerbuzz.com. If you have been tearing your hair out trying to figure out why that heavy, rune-carved door in the depths of the castle basement refuses to budge, you are in the exact right place.

Unlocking the secret vault is one of the most rewarding milestones in the game. Not only does it gatekeep some of the most legendary endgame gear, rare crafting materials, and historical lore fragments, but it also tests your platforming, puzzle-solving, and exploration mettle.

Across regions from the bustling gaming hubs of New York and San Francisco to the tech-savvy communities in Seattle, Washington, players everywhere are searching for the elusive Royal Crown Jewels. Grab your torches, ready your lockpicks, and let’s dive straight into the ultimate walkthrough.

Phase 1: Understanding the Castle Basement Vault Mystery

Before you start sprinting blindly across the map, you need to trigger the quest line properly. Down in the Castle Basement, past the aging wine racks and the damp, echoing corridors, sits the Grand Vault Door. Etched onto its stone surface are five empty sockets shaped like regal ornaments, accompanied by an enigmatic Latin inscription roughly translating to:

“Only when the scattered glory of the crown is reunited in darkness shall the iron seal yield its ancient heart.”

To open this door, you must track down five distinct Royal Crown Jewels, each hidden in radically different biomes, guarded by environmental puzzles, mini-bosses, or clever platforming segments.

Phase 2: Location Guide – Finding All 5 Scattered Royal Crown Jewels

1. The Ruby of the High Rook (The Castle Ramparts)

• Location: The highest point of the upper battlements.
• The Puzzle: While it is technically part of the castle structure, reaching this jewel requires going up rather than down. Head to the West Guard Tower and climb the spiral staircase to the broken rookery.
• Collection Strategy: You will need to time your jumps across the collapsing wooden scaffolding. Avoid the nesting Griffon guards (throw a raw meat bait if you are struggling with combat). Once you reach the apex, the Ruby of the High Rook rests atop an ornate stone pedestal bathed in sunlight.

2. The Sapphire of Sunken Depths (The Grotto Caves)

• Location: Accessible via the hidden waterfall cave behind the outer moat.
• The Puzzle: This jewel is submerged in an underwater grotto that features a synchronized pillar-pressure plate puzzle.
• Collection Strategy: Bring water-breathing potions or ensure your stamina stat is sufficiently leveled. Dive into the central chamber and activate the three statues in chronological order based on the sun-moon-star reliefs carved on the cavern walls (Left: Moon, Center: Sun, Right: Star). Doing so drains the secondary basin, letting you pry the Sapphire of Sunken Depths from the jaw of a stone serpent.

3. The Emerald of the Overgrown Crypt (The Whispering Woods)

• Location: Deep within the foggy labyrinth of the southern forest graveyard.
• The Puzzle: The crypt door is sealed by a shadow-weaving puzzle. You must use your portable light source or torch to align the statues’ shadows with the markings on the floor.
• Collection Strategy: Beware of ambient ghoul spawns that disrupt your positioning. Once the crypt opens, navigate past the swinging pendulum blades. The Emerald of the Overgrown Crypt rests inside a sarcophagus guarded by a restless crypt-keeper mini-boss. Defeat him by exploiting his fire vulnerability.

4. The Amethyst of the Royal Library (The Forbidden Archive)

• Location: Hidden behind a rotating bookshelf puzzle inside the castle’s upper library.
• The Puzzle: This is a pure logic puzzle. You must inspect three historical logs scattered on reading desks throughout the library to find out which fictional monarchs “died of poison,” “died in battle,” or “died of old age.”
• Collection Strategy: Pull the corresponding busts in the correct historical sequence: The Red King, The Blue Queen, and The Green Prince. The bookshelf will slide open with a grinding mechanical groan, revealing a small treasury room where the Amethyst of the Royal Library glimmers safely inside a glass display case.

5. The Diamond of the Obsidian Abyss (The Volcanic Mines)

• Location: The deepest, hottest tier of the abandoned mining shafts connected to the castle’s sub-level.
• The Puzzle: Extreme heat management and rail-cart navigation.
• Collection Strategy: Equip your heat-resistant armor set. You will need to hop into a rusty minecart and manually switch track levers at high speeds to avoid lava pools and collapsing ceiling hazards. At the final terminal station, the Diamond of the Obsidian Abyss sits on an altar of cooled magma. Grab it fast before the thermal damage ticker overwhelms your health bar!

Phase 3: Unlocking the Secret Vault Door

Now that your inventory holds all five glittering artifacts—the Ruby, Sapphire, Emerald, Amethyst, and Diamond—it is time to return to where your journey started: The Castle Basement.

1. Approach the heavy iron Vault Door.
2. Interact with the empty recessed sockets one by one.
3. Place each jewel into its corresponding color-coded slot (Red top-left, Blue top-right, Green center, Purple bottom-left, White bottom-right).
4. Watch the cinematic sequence as the ancient mechanisms grind into motion, the magical runes flare up with blue energy, and the heavy stone slab swings open into darkness.

Pro-Tips for Speedrunners and Completionists

• Don’t Rush the Combat: In areas like the Whispering Woods and Volcanic Mines, rushing blindly will trigger traps or trap you in corner-swarms. Clear mobs methodically.
• Audio Cues Matter: When solving the library and grotto puzzles, listen closely for distinct mechanical “clicks.” These confirm you have positioned a lever or statue correctly.
• Inventory Management: Ensure you have at least 5 free inventory slots before starting your collection run. You cannot pick up a jewel if your satchel is completely full!

Frequently Asked Questions (FAQ)

1. Can I collect the Royal Crown Jewels out of order?

Yes! Once you have unlocked access to the open-world map, you can collect the five jewels in any sequence you prefer. However, following the intended level-scaling path makes survival much easier.

2. What happens if I die while carrying a Crown Jewel? Do I lose it?

No, the game treats quest-critical items like the Crown Jewels as permanent key items. You will not drop them upon death, though you may respawn at the nearest checkpoint.

3. Do I need any special tools or high-tier lockpicks for these jewels?

Most jewels are locked behind puzzles or environmental traversal rather than traditional lockpicking minigames. However, bringing a few standard lockpicks is always recommended for extra chests found along the way.

4. What kind of loot is hidden inside the castle basement vault?

Inside, you will find the legendary Royal Sovereign Armor set, a massive pile of gold currency, and a unique blueprint needed for end-game weapon crafting.

5. Is the vault door repeatable on multiple playthroughs?

Yes. If you start a New Game Plus (NG+) run, the vault resets, allowing you to collect the jewels and raid the vault all over again for scaled rewards.

6. Can I open the vault door with only four of the five jewels?

Negative. The magical seal requires all five elemental frequencies (represented by the five distinct gems) to neutralize the barrier. Missing even one will keep the door locked tight.

7. Why isn’t the bookshelf rotating in the Royal Library?

Make sure you have interacted with all three historical books on the reading tables first. The puzzle mechanism remains locked until your character “discovers” the solution clues.

8. How do I survive the intense heat in the Volcanic Mines?

Drink a Cool-Brew Elixir before entering the mine shafts, and equip any gear items featuring baseline thermal or fire resistance to slow down health depletion.

9. Are there any hidden achievements tied to this vault?

Yes! Opening the vault unlocks the prestigious silver achievement/trophy titled “Heir to the Crown.”
