There are two ways to obtain TM71 Stone Edge in Pokémon Platinum:
- There’s one copy of TM71 deep within Victory Road, near the end of the main game. This location requires the Hidden Moves Strength, Rock Climb, and Rock Smash to reach.
- Unlimited copies of TM71 can be purchased from the TM seller at the Battle Frontier. They cost 80 Battle Points (BP) each, which you’ll have to win through the Battle Frontier’s various facilities.
Stone Edge is a damage-dealing Rock-type physical move that has a high base power and critical-hit ratio, but at the cost of accuracy.
Getting TM71 Stone Edge (All Methods)
Location #1: Victory Road (Step-by-Step)
The first copy of TM71 Stone Edge is only available toward the end of the game, after you’ve collected all eight Badges and reached Victory Road.
It requires Pokémon with these HMs:
- Rock Smash
- Rock Climb
You could also pick up a few healing items and Repels if you’re running low, because Stone Edge is found in the far depths of Victory Road’s cave, and it can take a while to reach.
Once you’re prepared, Fly to the Pokémon Center at the entrance to Victory Road. Then head inside the cave.
Upon entering the cave, go straight north to cross the bridge leading to the hill.
Take a right onto the next bridge, heading east.
Ignore the stairs leading down a level, and instead cross the third bridge, which leads northward.
Once on the next hill, take an immediate right and use Rock Climb on the rocky wall that takes you to the ground level.
Then head left and pass under both of the bridges.
Continue heading west, ignoring the ledge you’ll run by. Then approach the first staircase you see.
Ascend the staircase, then move north to pass under the bridge.
Battle the Ace Trainer here if you haven’t already, then climb the two staircases to the northwest. This will bring you to the cave’s second floor.
On the next floor there is a little bit of puzzle-solving to be done.
You will see two breakable rocks directly to your south—use Rock Smash on the left rock to pass through.
Wind around the rocks to the next area, where you will eventually see three movable boulders blocking your path.
Start by pushing the right boulder southward.
Now push the boulder to your left further left.
Now you will be able to position yourself behind the middle boulder in order to push it to the south.
This will open a path for you to enter the next section to the southwest.
Battle the Ace Trainer as you head left and pass the rocks and boulders.
Then place yourself above the leftmost boulder and push it southward.
Circle around through the new path, so that you can reach the breakable rock below.
Then use Rock Smash on the breakable rock that’s in the way.
Now stand below the last boulder you pushed, and then push it back north, into its original position.
The path to the southeast is now open, so head down there.
Use Rock Smash on the next rock in your way, then walk into the next area where a new Ace Trainer is waiting to battle.
Continue moving eastward and you’ll find three more movable boulders.
Stand to the left of the upper boulder and push it to the right.
Then head north through the upward hallway, battling the Veteran trainer as you pass.
At the end of this corridor, head down the staircase.
The only reason you needed to descend the staircase was to reset the last boulder you pushed; so now you will be able to easily push it in a different direction.
So go back up the staircase and head back to the boulders you were just at.
Come back down the hallway, and push the middle boulder in between the other two.
Now you’re able to head down the hallway to the east.
Travel as far east as you can. Here you’ll find another boulder puzzle.
Position yourself on the left side of the southernmost boulder and push it to the right.
Keep pushing the boulder until it is against the eastern wall.
Circle up and around to the northwest, and shove the northern boulder to the left.
Use Rock Smash on the rock between the two boulders here.
Now step into the space that rock occupied, and push the southern boulder further south.
The path to the northeast is now open. Head that way, winding around the rocks and bicycle ramps.
At the end of the hallway, head northward and battle the two Ace Trainers.
You will need to ride your Bicycle for this next part.
Make sure your Bicycle is in fourth gear (the faster one). And then get into a starting position in the upper-right corner of this room (in line with the ramps).
Hit the first two ramps moving west as fast as you can & you’ll jump over the rocks.
But before you hit the third ramp, take a sharp turn up the northern past to avoid the third jump.
If you accidentally jump the third ramp, you will need to start over.
Once you’re in the northern alcove here, TM71 Stone Edge will be visible on the ground.
Location #2: Battle Frontier (Repeatable)
This second method is only achievable after you’ve beaten the Elite Four and Sinnoh’s Champion.
You can buy an infinite number of copies of TM71 from the TM seller at the Battle Frontier, though they’re a bit pricey at 80 BP.
To reach the TM seller, first head into the main Battle Frontier entrance directly northeast of the Pokémon Center outside.
Pass through the reception area to enter the center of the facility.
You will find yourself in a massive room with staircases leading to many other rooms. In the center you will see vendors at various kiosks in a collective market area.
The TM seller is at the southeastern kiosk, with the red-and-white striped canopy. Speak with her to see the TM listings.
TM71 Stone Edge is one of the most expensive TMs for sale, costing 80 BP per copy.
BP must be earned at the various battle facilities (located in five rooms at different sections of this central room), through battling under different challenging conditions.
Stone Edge Details + Uses
Stone Edge is a damage-inflicting, Rock-type physical move. It has a high base power stat and critical-hit ratio, but reduced accuracy.
|Stone Edge Move Details|
|PP||5 (max. 8)|
Stone Edge is one of the best Rock-type moves in the game.
Its increased critical-hit ratio means that one out of every eight attacks will do critical damage, roughly doubling the amount of damage dealt—this means close to a 200 base power approximately 12.5% of the time.
Unfortunately, as with most powerful Rock-type moves, Stone Edge has a reduced accuracy of 80%. Though this can be mitigated by +10% by having the user hold a Wide Lens.
Although the move’s 5 PP means you won’t be able to rely on it for long.
But it’s still a very solid Rock move, especially with a Wide Lens and a few PP Ups.
Note: If used in a Pokémon Contest, Stone Edge will generally earn the user 3 Appeal Points, depending on how well the other contestants’ moves have gone.
