You’ll find TM80 Rock Slide on the second floor of Mistralton Cave. But to reach the TM’s location you’ll also need a few moves:
Mistralton Cave is located on Route 6, and it sits between Mistralton City and Driftveil City.
TM80 Rock Slide Location (Step-by-Step)
Step 1: Starting at the Driftveil City Pokémon Center, head north towards the road above the Center.
Step 2: Right above the Pokémon Center is a staircase. Don’t climb the stairs, but head west past the stairs.
Step 3: The city’s western exit leads directly to Route 6. Continue west onto the route.
Step 4: Keep going west, walking across the wooden bridge.
Step 5: West of the bridge you’ll come to a line of trees that won’t let you go any further west. You’ll also be in a large patch of tall grass.
Turn and head north through the grass here.
Step 6: Keep going north and then turn east to follow along this path.
Eventually you’ll find another wooden bridge up ahead with a blonde NPC on it – cross over this bridge as well, going to the east.
Step 7: At the end of the bridge just head up north.
Then cross the next bridge you’ll see to your left, walking west over the bridge.
Step 8: At the end of this bridge, continue west on the path, curving up to get around the white picket fence.
Step 9: Walk west past the Research lab building and you’ll see another bridge – but don’t cross this one.
Instead, turn north to go up a narrow path sitting directly between the stream of water and the trees.
Step 10: Walk all the way up this path until you’re at the very end standing by the water. Then use HM03 Surf on the water here.
Step 11: You can’t go directly east across the water since you’re blocked by rocks. But you can Surf across the water going north & land onto the grassy patch of land across from you.
Do that, then cross through the grass eastward to bypass the rocks in the water. Now you can use Surf on the other side of the rocks to surf on the water going east.
Step 12: Keep east across the water, passing the Research Station below.
Step 13: Continue east until you reach land straight ahead on your right-hand side.
Disembark here and then enter Mistralton Cave.
Step 14: After entering the cave, use TM70 Flash to illuminate your surroundings.
Step 15: Now that the cave is lit up, head south from the entrance.
Step 16: Ahead is a large boulder.
Use HM04 Strength to push the boulder into the nearby hole (just push it over right & then push it down).
Step 17: Now that the hole is covered, continue south through the cave by walking over the boulder in the hole.
Step 18: Once you go south down the stairs and turn east, you’ll quickly find another boulder is blocking the path here.
Use Strength to push the boulder into the hole directly to the right.
Step 19: Now walk east over the covered-up hole, then head north up the flight of stairs.
Step 20: Continue north from the top of the stairs.
Step 21: Take your first available left turn through the cave. Then right when you see a Hiker NPC you’ll want to start going southwest (pictured below).
You’ll want to head towards a big set of stairs leading up to a new area.
Step 22: Climb the stairs going up to the next floor.
Step 23: You should spot another boulder from the top of the stairs.
Head down and use Strength to push this boulder over its hole to the right.
Step 24: Now head east over the covered hole, and then turn going northeast to go up the first set of stairs & walk onto the elevated path.
Step 25: Continue east down this elevated pathway & then take the small set of stairs down at the end of this rocky platform.
Once you’re down the stairs at the end, head north past the boulder ahead (no need to push this boulder at all).
Step 26: Keep going north through the cave and you’ll eventually climb another set of stairs straight ahead.
Step 27: Head up this elevated platform and then wrap around going west – this leads you down a very narrow path on this elevated platform.
Step 28: TM80 Rock Slide will be in a Poké Ball on the ground at the end of this narrow path.
Rock Slide Details + Uses
|Rock Slide Move Details
There are very few Rock-type moves better than Rock Slide – especially in Black & White.
Granted, this move isn’t the strongest nor the most Accurate. But it is consistent.
The attack’s secondary effect is a big plus as well: it causes its target to flinch 30% of the time.
Many Rock-type Pokémon in Black & White learn Rock Slide via level-up, so venturing deep into Mistralton Cave for the TM may not be worthwhile.
On the other hand, TM80 can be taught to a majority of Pokémon regardless of typing. So it could be a great fit for eligible Physical Attackers in your party like Darmanitan and Conkeldurr.
