TM71 Stone Edge is located on the 2nd basement floor of the Challenger’s Cave (B2F). This cave can be found on Route 9 just before reaching Opelucid City.
But the entrance to Challenger’s Cave will be guarded until you defeat the Elite Four and Team Plasma. So this TM is only accessible in the post-game.
And to navigate the cave, you’ll need both TM70 Flash and HM03 Surf.
Flash will help illuminate the cave, and Surf is needed to cross the cave’s small body of water.
TM71 Stone Edge Location (Step-by-Step)
Step 1: Starting at the Opelucid City Pokémon Center, head west through the city.
Step 2: Keep walking west, passing the Trainer Tips sign.
Step 3: Exit through the green tunnel at the west end of the city.
Step 4: The tunnel’s exit leads to Route 9.
From here, turn and head south through the gap in the white fence.
Step 5: Through the fence are patches of tall grass.
Turn and head west through the grass just past the fence.
Step 6: You’ll eventually see an old couple standing on the main road above you. Once you reach those NPCs, turn and head south.
Step 7: Keep going south and ahead you’ll find two sets of stairs. Head down these stairs and enter the Challenger’s Cave.
Step 8: Upon entering the cave, use Flash to light up the area.
Step 9: Now that you’re able to see, head north and take the stairs in the top-corner down to the cave’s lower floor (B1F).
Step 10: On this floor just head east from the bottom of the stairs, passing the trainer with blue hair.
Step 11: Keep on the same path east through the cave.
Step 12: Once pathway ends, turn up and head north.
You’ll eventually see a pair of rocks on the left with a small gap between them – walk in between this gap and head west.
Step 13: Continue west under the footbridge and climb down the stairs to the lower floor (B2F).
Step 14: Walk north from the bottom of the stairs.
Step 15: Directly ahead you’ll find a body of water. Use Surf on the water.
Step 16: Surf across the water heading east.
Step 17: Keep going east across the water, passing through the channel in-between two pieces of land.
Step 18: Stay east through the water and you’ll eventually pass by some small rocks above you.
Step 19: You’ll eventually hit a point where the water ends – at this point you’ll want to disembark to the north and get onto land.
Step 20: Then turn and head east, climbing the flights of stairs you’ll run into.
Step 21: Once you climb these sets of stairs, turn and go south to head across a footbridge.
Step 22: After crossing the first footbridge, turn and head west across the next bridge.
Step 23: At the end of this footbridge you’ll want to veer south and head down the stairs.
Step 24: At the bottom of these stairs just turn right and head east up another flight of stairs.
Step 25: Continue east, passing by the trainer dressed in black.
Step 26: After passing the trainer, the cave’s path winds south. Follow the path to the right & south, and then walk up the big set of stairs you’ll see (they lead up to the west).
Step 27: Continue west from the top of the staircase.
Step 28: This path west leads to another footbridge.
Turn and cross the bridge heading south.
Step 29: Then at the end the footbridge just turn to the right & head east down a flight of stairs.
Step 30: Continue east from the bottom of the staircase.
Step 31: You’ll then come to another set of stairs to climb, and you’ll see a footbridge located down below you.
Cross this bridge heading south.
Step 32: After crossing the bridge you’ll notice a set of stairs southwest of you – take these stairs down from the rocky platform you’re on.
Step 33: Ahead to the west is a large brown rock. Keep going west until you see the rock, then turn & go north to follow this passageway.
Step 34: To the north is a large set of stairs. Climb these stairs heading west.
Step 35: At the top of the staircase is another footbridge – continue west across the footbridge here.
Step 36: Then veer south at the end of the bridge & go down the small set of stairs you’ll see.
Step 37: From the bottom of this staircase, turn west and climb down the next set of stairs.
Step 38: Directly to the west is yet another staircase.
Climb these stairs up (they’ll take you northward).
Step 39: This big staircase leads to the center of the basement floor.
Once you’re at the top of these stairs, turn right and go down a flight of stairs, then walk a bit up and turn to the left to go down another set of stairs (this leads to a small rock in the center of the area).
Step 40: From the small rock, begin walking east – you should see another small staircase coming up.
Step 41: Turn north and climb this first staircase you run into – it’ll lead you onto a raised rocky platform.
TM71 Stone Edge will be found in a Poké Ball on the ground directly ahead at the top of these stairs.
Stone Edge Details + Uses
|Stone Edge Move Details|
Stone Edge is the most powerful Rock-type move in Black & White. It dishes out Physical damage at 100 base Power.
While the attack doesn’t have great Accuracy (80%), the move is more than just a heavy hitter.
Stone Edge’s secondary effect increases critical hit chance by one stage.
Critical hits land for double the normal damage, which is a significant increase for dominating moves like Stone Edge.
The chart below outlines how critical hit ratio is affected by stage. This stat typically starts at stage 0, but Stone Edge provides an immediate boost to stage 1 on first use.
|Stage||Critical Hit Chance|
Each time you use Stone Edge it has a 12.5% chance of delivering a critical hit.
You can further increase this chance by giving your Pokémon a Razor Claw to hold, which provides another crit boost of +1 stage.
Who To Teach Stone Edge To
Stone Edge is a Physical attack, so it’s better to teach it to Rock-type Pokémon with a strong Attack stat.
Rampardos is without a doubt the best user of Stone Edge in Black/White, as its Rock typing and 165 base Attack is borderline unfair.
But Rhyperior, Gigalith, and Tyranitar are also great choices for TM71.
