It takes time to catch all the Pokémon in the Galar region, but it's hard to find the hardest to find list. Pokémon Sword and Shield. There's a decent Pokemon called Grindur that you capture in several places. It is as a Grass and Ice Pokémon that you can then associate a Ferrothorn at level 40.
You can find Grindur in these places:
- Motostoke Riverbank during a sandstorm
- Stony Wilderness during a snowstorm
- Bridge field during normal, overcast, rain, thunderstorm, intense sun, snow and hail, snowstorm, sandstorm and thick fog
- Route 4 in all weathers
You want to experience Motostoke Riverbank during a sandstorm to have the best chance of catching this elusive Pokemon. You must use a Fighting or Fire-type Pokemon to deal enough damage. The majority of The Pokémon Grindur you will encounter will range from level 26 to 28, but if you find one on Route 4 it will be much lower, between levels 13 to 15.
You have the possibility of encountering him in a Max Raid in the Wild Area, but there is a slim chance of this happening. It's best that you check the other three locations during those particular weather periods to get the maximum chance of capturing an ideal Grindur. If you encounter it in a max level raid, it ranges from 25 to 30.
Keeping this Pokemon in your roster is ideal, especially if you get it early on Route 4. You have the choice to morph it at level 40 into Ferrothorn, and it remains a Grass and Ice-type Pokemon. You won't need anything special to change it.
