Route 14

From Tapu Village, head to Route 14's black sand beach. Search the corner to the left of where the hill meets the sand to find a hidden Pearl.

Summon Lapras near the shoreline and paddle south to an offshore platform.

Go up the stairs on the east side of the platform.

After a cutscene (a non-interactive cinematic the game plays automatically), head to the top of the platform to battle Veteran Brone. He uses a Level 36 Whiscash (Water/Ground) and a Level 36 Honchkrow (Dark/Flying). Whiscash is 4x weak to Grass and immune to Electric. Honchkrow is weak to Electric, Rock, Ice, and Fairy, but beware its Steel Wing.

Past Brone, collect TM30 Shadow Ball from the center of the rubble.

Return to the sea and paddle north to the entrance, then head south-east along the beach.

Near a hiker obsessed with Surfing Pikachu, find a collapsed road on the north. Continue south-east towards the path's bend.

Talk to Fisherman Hisato near the waterside. He uses a Level 34 Feebas (Water) and a Level 34 Gyarados (Water/Flying). Gyarados is double weak to Electric.

Return to the collapsed road near the entrance. Walk on the small space where the damage is greatest to go onto the road.

Grab Totem Sticker #068 in the dark space between the rubble on the road.

Continue to the top of the intact road and head east.

Find a Max Potion below the hillside.

Leap over the crooked ledge. East of the collector, find Totem Sticker #069 among a gang of Murkrow.

Battle Collector Kawika, who uses a Level 34 Larvitar (Rock/Ground). Larvitar is double weak to Grass and weak to Water, Ice, Fighting, and Steel.

Head south down the slope towards the dark sand, near the trial gates where Acerola waits.

Continue east past the trial gates, around the fallen road section, to find a Max Revive.

Return to the beach below the trial gates. Call Lapras and paddle south towards the eastern sea corner.

Battle Swimmer Keoni, who uses a Level 34 Pyukumuku (Water). Pyukumuku uses Pain Split and Innards Out.

Return to shore and head north up the stairs between the trial gates.

At the top, Acerola will explain the trial rules. Enter the supermarket via the north-east door to begin.
