The Rock Incense is located in the southeast corner of Fuego Ironworks. The only requirement for getting this item that you’ll need a Pokémon that can use Surf to reach the building.
And this is also the only Rock Incense you can get in Pokémon Platinum (other than trading).
Rock Incense Location (Step-by-Step)
The Rock Incense is located inside the Fuego Ironworks. This is an out-of-the-way refinery located northwest of the Valley Windworks.
All you need is a Pokémon that can use HM03 Surf in order to obtain the incense.
Finding Fuego Ironworks
The quickest way to the Ironworks is to Fly to Floaroma Town and head east from the PokéCenter on the main road.
Leave Floaroma Town through the eastern path, and continue east on Route 205.
When you arrive at the bridge leading north to Eterna City, use Surf on the bridge on the left-hand side & keep surfing west up the river.
Stay on course as the river curves to the north.
Ignore the clearing to the east as you continue traveling north on the water.
Turn westward with the river and you should eventually see some land with a patch of tall grass.
When you reach the grassy field, step ashore and head north to cross through the grass.
Up ahead you can enter the giant Fuego Ironworks building to the north.
Finding the Rock Incense
The Fuego Ironworks building is a big puzzle.
On the facility’s floor you’ll find innumerable yellow Spin Tiles with red arrows on them; stepping on one tile will send you spinning out of control in the direction of the arrow, leaving you unable to change direction until something breaks your momentum.
Here’s the exact steps to follow for getting the Rock Incense:
From the entrance, head left and step on the first Spin Tile to see the puzzle’s mechanism in action.
Ignore all the other Spin Tiles around you and just head west – keep going until you get to the southwestern corner of the Ironworks.
At that point, turn and head up a bit, then step on either of the Spin Tiles pointing northward (we’ll take the right-hand path).
When you come to a stop, head southeast and pass down by a blue container.
Then step on the southernmost Spin Tile in this area, and let it send you from Tile to Tile.
Wait for the Spin Tiles to lead you to a stopping point near some red barrels.
From the red barrels, step on the Spin Tile directly to the north of your position.
Then step onto the Spin Tile to the immediate southeast of your stopping point.
This will take you through a few passageways & when you stop spinning, backtrack to the north a bit – you should see a small opening where you can turn eastward (pictured below).
Go into this opening and then step on the only Spin Tile in the small square enclosure.
You will come to a stop by running into an oil drum.
From there, step on the Spin Tile in the southeastern corner of the Ironworks (this sends you into a blue crate).
Once you’re stopped you’ll see a column of three Spin Tiles to your left; choose the top Tile and let it send you from place to place.
Once you come to a stop at another blue container, turn towards the right and walk back the way you came. You might notice there’s actually an item sitting in the corner of this small enclosed area (top-right corner).
So avoid stepping on all the Spin Tiles as you approach the Poké Ball item in the northeast corner of this section (pictured below).
Pick up the Poké Ball item to acquire the Rock Incense.
Note: This is the only Rock Incense you can get in the game.
Rock Incense Details and Uses
Uses In Battle
The Rock Incense increases the power of Rock-type moves by 20%, making its effect identical to the Hard Stone held item.
The ideal holder of a Rock Incense is a Rock-type Pokémon (for added STAB damage) with high Attack and/or Special Attack, depending on the Pokémon’s moveset.
Granted there are items with higher move boosts than the Rock Incense provides, but they often come with caveats. For example:
- The Life Orb increases the power of all moves by 30%, but saps 10% of the holder’s maximum HP to perform each attack.
- Choice Bands and Choice Specs increase physical and special move damage by 50% respectively, but at the cost of the holder being locked into using the same move repeatedly for that battle.
So all things being equal, the Rock Incense is the safer option for Rock move users in your team. Even if it’s not the more exciting held item to chose.
Uses Outside of Battle
You can use the Rock Incense in Pokemon breeding to breed a Bonsly, the pre-evolution form of Sudowoodo.
You’ll need to get two Sudowoodo of opposite genders, or you’ll need either of these combinations of Pokémon:
- A Sudowoodo and a Ditto
- A Sudowoodo and another Pokémon from Sudowoodo’s Egg Group
You’ll place them both in the Solaceon Day Care and give a parent the Rock Incense to hold.
Breeding a Bonsly with the Rock Incense
Once you have your breeding pair of Pokémon that can breed with your Sudowoodo, give Sudowoodo the Rock Incense to hold.
You’ll then find the Day Care in Solaceon Town northwest of the Pokémon Center.
Go inside and give your Pokémon to the Day-Care Lady at the front desk.
After walking around for a while, return to the Day Care and speak with the Day-Care Man outside. If your Pokémon have made an Egg then he will give it to you.
You can also check your Pokémon’s Egg status on the Day-Care Checker Pokétch App screen, which will display a picture of an Egg if your breedable Pokémon have produced one.
To hatch your Egg, you have to carry it in your party while you take a certain number of steps – in this case for a Bonsly egg you’ll need between 5,140 to 5,396 steps.
Although if you have any Pokémon in your party with the Flame Body or Magma Armor Abilities then that number will be halved.
But if you follow the process as described above, a Bonsly will eventually hatch from the Egg.
