Route 8 (Hammerlocke Side)
Head north past the number 8 signpost. At the first corner, turn left and go down the steps to the lower level. Next, go north through the dried grass. On the right, is a path leading to a ladder going down. Go that way. You can also continue north, but there’s nothing special over there (except for more tall grass). After climbing down the ladder, there’s a trainer on the right.
Roselia is an evolved Budew; it’s weak to Fire, Flying, Ice and Psychic. Hattrem you’ve already fought before, in Bede’s party.
Next, climb up the ladder to the right of the Doctor. Turn right, then navigate through the dried grass towards the south. Grab the Shiny Stone at the far end, which you probably saw earlier. Go back around and proceed north. Head down the stairs on the left to return to the lowest floor. Down here, climb up the ladder directly ahead.
Turn left and climb up the ladder on the left. Up here, pick up the nearby TM96 Smart Strike. Go back down the ladder, then continue right. There’s another ladder leading to the lowest level. After going down it, you’ll be in a confined space full of dried grass. Head for the bottom-left corner to find 3 Hyper Potions. Then clamber up the ladder on the right.
Go forward and climb down the nearby ladder on the right. Make your way north, through the patches of dried grass. There will be an item capsule on the left, just out of reach. After you go past it, turn left and search the corner by the wheelbarrow for an Elixir. Continue north and turn left at the next corner. Then jump over the ledge on the left.
From here, head south, then go through the dried grass to the east. Pick up the 3 Luxury Balls next to the ledge, which you passed by moments earlier. Next, make your way west, through more dried grass. Around here, there will be a caterpillar-like Falinks crawling slowly between small tunnels to the north and south. Despite appearances, it’s a pure Fighting-type.
Further west, head towards the bottom-left corner to find a Max Revive. Then begin to follow the path north. On the left, there are stairs leading up to the highest level. Be mindful of a trainer walking along the left-hand side of the stairs.
Dreepy is a new Dragon and Ghost-type that you probably can’t catch for a while. It’s weak to Ice, Ghost, Dark, Dragon and Fairy. Meanwhile, Vullaby can be found here, if you playing Shield that is. This oversized vulture is weak to Electric, Rock, Ice and Fairy.
When you reach the highest level, search the rock in the far corner for a Big Nugget. Afterwards, go back and follow the path north, then east. Once you reach the end of the dried grass, there’s a trainer to the north who’s walking to and fro.
This difficult to pronounce Pokémon can be found on this route, although it’s rare. It takes 4x damage from Ground and 2x damage from Fire and Fighting. Be cautious of Nuzzle, which can instantly paralyse non-Ground Pokémon.
Go down the ladder to the right of Charles. In this section, there’s a small walled off area in the middle, which you can enter via the east. Meanwhile, there will be a relatively fast Falinks crawling between two sets of tunnels–horizontally across the north and vertically across the east.
If you want to avoid the Falinks, you’ll want to go anti-clockwise around the walled off area. Regardless, be sure to enter the walled off area to retrieve the King’s Rock inside. If it’s safe, go over to the top-right corner, where two of the tunnels meet, and search the sparkling spot for a Nugget. Afterwards, go up the stairs on the right.
At the top of the stairs, watch out for another slow-moving Falinks traveling between two tunnels. Past the Falinks, climb up the ladder to the highest level. Up here, there’s an exit directly ahead. But first, travel west from the top of the ladder. Your view will be slightly obstructed by the wall along the south.
Halfway along, there’s a Crustle walking around; it’s so wide that you’ll have to battle it to proceed. Keep going and grab the TM43 Brick Break at the end. Return to the top of the stairs, then begin heading north towards the exit. Instead of leaving, turn right towards the camp site.
There will be two trainers here blocking the way. One of them–the bloke–is busy gazing at his phone. Meanwhile, the other one–the lady–is looking south-east to south-west. If you want to avoid a confrontation, dash to the south when the lady is looking south-east. Then dash east when she’s looking south-west.
Colleagues Alison and Jordan
This is a Double Battle, where Alison uses Hippowdon and Perrserker, while Jordan uses Excadrill and Lucario. At the start of the fight, Hippowdon’s Sand Stream will summon a sandstorm, which damages all Pokémon unless they’re Ground, Rock or Steel-types (which all of their Pokémon are).
In the right corner, Hippowdon is an evolved Hippopotas. It can use Yawn to make your Pokémon fall asleep on the next turn. Try to focus your efforts on it first. Next up is Perrserker, an evolved Galarian Meowth. It can use Fake Out for a turn 1 flinch and Swagger to confuse your Pokémon.
In the left corner, Excadrill is an evolved Drilbur. It loves to use Dig to hide underground for one turn, hoping the sandstorm exhausts your Pokémon. It’s weak to Water, Fire, Ground and Fighting. Next is Lucario, an evolved Riolu. It’s weak to Fire, Ground and Fighting.
Head right from the camp site, through the narrow gap that’s easy to miss. At the very end, there’s a Terrain Extender up for grabs. Finally, go back left and exit via the northern tunnel. If you need a break, you can leave and fly back to the camp site from before.
The main new Pokémon here is Falinks, which resembles a caterpillar, but is a Fighting-type. You can find 'em crawling between tunnels from the halfway point towards the end. There are lots of old favourites as well, such as Pawniard (Dark/Steel) and Golett (Ground/Ghost).
Plus Togedemaru, a rare Electric and Steel-type. Also, Sword players can find Rufflet (Normal/Flying) and Solrock (Rock/Psychic), while Shield players can find Vullaby (Dark/Flying) and Lunatone (Rock/Psychic). There are many evolved Pokémon as well, ranging from Sandaconda to Drapion.
Route 8 (Circhester Side)
You’re still on Route 8, but the weather has taken a turn for the cold. Brr… Head north across the bridge going over the river. On the other side, there are patches of tall grass towards the north and the east. Meanwhile, the exit is located between them, to the north-east. Just be mindful of a policeman standing to the right.
Police Officer Bobby
Bobby has two canine friends. First up is Arcanine, an evolved Growlithe. Pay attention to its Intimidate ability, which reduces your Pokémon’s Attack. Next is Boltund, which is an evolved Yamper. This one is carrying Nuzzle, which it may use to paralyse its opponents.
This is a tiny area, but there’s plenty of Ice-types to be found. Snom is a new Ice and Bug-type, which evolves into Frosmoth when it’s night time and it’s happy enough. Sword players can find Galarian Darumaka hiding in the grass. Its evolved form can become Ice and Fire during Zen Mode.
Other cool Pokémon include Sneasel (Dark/Ice), Snorunt (Ice) and Vanillish (Ice) found above ground and Snover (Grass/Ice) and Delibird (Ice/Flying) hiding in the grass. Of note, Snorunt can evolve into two forms; females can use a Dawn Stone to evolve into Froslass.
