Leading north from Mauville City, the lengthy Route 111 is a unique path split into three parts by the large desert in its center. A powerful sandstorm rages on, forcing travelers to detour around it on their way past. A house belonging to the Winstrate family stands at the water's edge.
The upstanding Winstrate family loves challenging visitors to battle. Speak to the man at the front door, and he asks if you would like to take his family on in four back-to-back battles, with no break to heal your team. Defeat each one in turn, and afterward, enter the house and talk to Victoria to receive a Macho Brace as a reward.
Gabby and Ty, the reporter-cameraman team you met back in Slateport, can be found standing along the road. Accept their challenge to demonstrate your battle prowess, and they will beg for an interview afterwards. Find a TV afterwards for a chance to hear about yourself on the news!
A pair of Team MagmaR/Team AquaS Grunts are guarding the cable car station, so no one can reach the summit of Mt. Chimney right now. In addition, the elevated terrain makes westward travel impossible, so the only other way forward is a steamy tunnel through the mountainside.
The sweltering Fiery Path, a passage that leads through the base of Mt. Chimney, is filled with Pokémon that thrive in the heat. The main passage leads to the north side of Route 112, while a pair of boulders prevent anyone from exploring the oppressive side tunnels for now.
As you proceed northward, you find a boy staring at a large tree. Speak to him, and he explains that he is considering using a certain move to create a room for himself inside the tree. He gives you TM43 (Secret Power) so that you can establish your own Secret Base in any of the suspicious-looking trees, wall markings, and clumps of grass scattered across the region. A Trainer can decorate their Secret Base as they wish, and can display up to 16 decorations.
The Glass Workshop stands near the route's west end. Step inside and talk to the owner to receive a free Soot Sack, which can be used to collect ash by running through ash-covered tall grass. The amount of ash collected is determined by the number of steps you've walked through ash-covered grass. The constantly-falling ash replenishes these piles whenever you return to the area.
Speak with the workshop owner to learn how much ash you've collected. By providing him with the correct amounts, he is able to create valuable glass items.
