|Rare Bone Acquisition Methods
|The Underground—Obtainable by digging in the mining minigame
|Turnback Cave—Found in Giratina’s room by reaching it after passing through 4-15 rooms while Giratina is not present
Rare Bones can be found in two locations in Platinum: the Underground and Turnback Cave. Both of these methods are repeatable, but they also require a fair amount of patience.
The most fruitful place to find Rare Bones is Turnback Cave. However, this location isn’t available until after you enter the Hall of Fame, whereas the Underground can be accessed as early as your first visit to Eterna City.
Acquiring Rare Bones
The following two methods of finding Rare Bones are ordered starting with the earliest available method, which is digging for them in the Underground.
Method 1: The Underground
You can find unlimited Rare Bones in the Underground, which is accessed by using the Explorer Kit from your Bag’s Key Items pocket.
When you have control of your character after reaching the Underground, head for one of the glittering areas shown on the map. These indicate hidden treasures—and potentially Rare Bones.
Tap the touch screen to sense hidden treasures lodged inside bulging walls.
These spots will sparkle when your sensor passes over them.
Walk up to one of these spots and Press A, then select Yes to start a mining minigame.
The game will start by informing you of the number of treasures hidden in the wall.
To play, alternate between your hammer and your pickaxe to dig as many treasures out of the wall as possible before the wall comes crashing down from the repeated banging.
The hammer breaks more rocks and dirt per hit, but causes the minigame to end more quickly; the pickaxe is weaker, but more precise and less damaging to the wall.
Rare Bones tend to be among the largest items in the walls thanks to their length, making them easy to spot. However, they can take a lot of effort to dig out, and you can make the wall collapse prematurely if you aren’t strategic with your tools.
When you’re ready to return to the surface, always make sure to send any items aboveground to your Bag.
You can do this by selecting Treasures in the Underground menu.
Bear in mind that Rare Bones truly are rare; along with other treasures like Iron Balls and Odd Keystones, Rare Bones tend to be some of the least-uncovered items in the Underground.
Method 2: Turnback Cave
More Rare Bones can be obtained from Turnback Cave, which is located just off of Route 214 via the Spring Path. It is the home of Giratina, and will only become available after you’ve escaped the Distortion World for the first time.
Part 1: Finding Turnback Cave
You’ll need a Pokémon that knows Rock Climb in order to reach Turnback Cave. A Pokémon with Defog is also highly recommended.
When you’re ready to visit the cave, Fly to Veilstone City and head south from the Pokémon Center.
Leave Veilstone City through the southeastern entrance gate.
On the other side of the gate, continue southward on Route 214.
Head east just after passing Psychic Abigail.
Turn south when you reach the narrow aisles created by the picket fences.
Continue southward through the picket fence maze, passing all the wandering trainers.
Pass Psychic Mitchell and keep moving southward.
Enter the Spring Path through the gap in the trees to the east.
Follow the Spring Path to Sendoff Spring at the end.
Enter the Spring’s clearing, then head east through the tall grass.
In the northeastern corner of this area, use Rock Climb on the rocky part of the wall.
At the top of the mountain, go either east or west. Both directions lead to the same place since you’ll be going in a circle.
Head north along the circular path overlooking the spring.
Use Rock Climb again at the next rock wall to reach the cave entrance down below.
Enter the cavern to go inside Turnback Cave.
Part 2: Solving the Puzzle of Turnback Cave
The first cave chamber you enter is thick with fog, so use Defog to clear it up.
This room has four doorways upstairs: one each to the north, south, east, and west.
In the middle of the wall in front of you is a partially-effaced inscription that gives you a clue about navigating Turnback Cave.
The most important part is the last bit: “…before 30 is surpassed…”
Start this puzzle by taking the door to north, west, or east—it doesn’t matter which.
The room you enter will either be full of breakable rocks, or it will be completely empty except for a pillar in the middle. It’s these pillar rooms that you’re looking for.
An inscription on each pillar will display two numbers.
The top number shows which pillar room you are in, while the bottom number shows how many rooms you’ve entered up to this point.
Finding all three pillars in under 30 rooms will result in you finding Giratina’s room, where you can pick up the Griseous Orb from the Distortion World portal.
But you’ll also find an item in Giratina’s room that changes depending on the number of rooms it took you to find all three pillars, as explained below:
- If you passed through 16-30 rooms, the item will be a Stardust.
- If you passed through 4-15 rooms, the item will be a Rare Bone.
- If you passed through exactly 3 rooms, the item will be a Reaper Cloth.
Turnback Cave and all of its rooms are randomly generated upon entry, so there is no quick or easy way of finding all three pillars within the 30-room limit.
Just keep choosing doors at random and you’ll get there eventually.
Once you find the third pillar, pass through any of the four doors to enter Giratina’s room.
A portal to the Distortion World will be in the middle, and just to the north of it, a Poké Ball.
If you have managed to reach Giratina’s room within the range of four and fifteen room changes, the Poké Ball will contain a Rare Bone.
This method of obtaining Rare Bones is somewhat more productive than finding them in the Underground, simply because you have higher odds of finding Giratina’s room within the 4-to-15-room range than digging up a bone in the mining minigame.
Rare Bone Details and Uses
Rare Bones only have one use: to be sold.
A single Rare Bone will fetch 5,000p, which makes it one of the most valuable items in the game, on par with Nuggets.
Selling highly-prized items like these can go a long way toward stretching out your wealth. This is especially helpful when covering the astronomical expenses of late-game activities like furnishing your Resort Area villa.
