The only copy of TM51 Roost is given to you by a female NPC on a hill on Route 210, located immediately northeast of Solaceon Town’s north exit.
You can access this TM as soon as you’re able to reach Route 210.
TM51 Roost Location (Step-by-Step)
To get your only copy of TM51 Roost, you’ll need to find a woman just a short walk northeast of Solaceon Town, on Route 210.
From Solaceon Town’s Pokémon Center, head north until you leave the town and hit Route 210.
By using your Bicycle in fourth gear, you can simply ride through the narrow path in the grass and up the muddy slope.
Once on top of the hill, follow the easternmost path, descending the right-hand staircase.
Follow the narrow question mark-shaped path in the grass here, and it will lead right to the NPC you need.
Simply speak to her and she will give you TM51 for free.
Since this is the only copy of TM51 in the game, it’s advised to take some special consideration when deciding which Pokémon you want to learn Roost.
