We last left off having explored roughly half of this route. Well, it’s time to check out the other half! From the entrance to Blush Mountain, head south-east. Over here, there’s a rocky hill surrounded by tall grass, with a scientist patrolling in an anti-clockwise direction. What could he possibly be looking for?
Time for a Rest?
If your Pokémon are feeling weary from all the exploring and battling, consider using Charizard Glide to fly back to a Pokémon Center. You can then fly straight back here by choosing the "Blush Mountain" feather icon on the map.
At the start of battle, Jayson may use an X Defend on his Porygon. Physical attackers should therefore be cautious, although the defense boost is unlikely to deter super-effective Fighting-types. Magneton, evolved from Magnemite, is weak to Fire and Fighting and doubly weak to Ground.
In any case, go over to the east side of the rocky hill. Next to the hill, in the space where there’s no grass, is an X Attack that deserves a loving home. Afterwards, head south-west from the hill towards the path divided by rocky terrain and tall grass. Continue south-west along the rocks or the tall grass, whichever takes your fancy.
On the other side, the exit to Route 13 is located straight to the west. Before leaving this route, head south to where a female swimmer is doing stretching exercises near some tall grass. If you want to get past unscathed, run past her while she’s stretching down.
The evolved form of Staryu has gained the Psychic-type and a considerable stat boost. It’s weak to Grass, Electric, Bug, Ghost and Dark-types. Sara sadly wasn’t smart enough and evolved her Starmie far too early, so it only has weak moves.
Either way, wade through the tall grass towards the south-west corner. Once you’re free of the grass, there’s a hidden PP Up if you search the far end. After that cool find, double back until you’re outside the tall grass. If you defeated all the trainers thus far, head north-east back to the "boss" trainer and challenge him to a duel.
Despite being the owner of Dragon Tail, his Pokémon are both Bug-types. Larvesta has a double weakness to Rock, and is weak to Water and Flying. His Pinsir has Brick Break to punish Rock-types and the Bug-type Z-Crystal. Fire or Flying-types are ideal to resist its Z-Move and dish out heavy damage.
Prove your worth and you’ll receive TM82 Dragon Tail . This move inflicts decent damage and forces the opponent to switch out. Regardless, return to the area just below the rocky terrain and tall grass combo, then go east towards the slope, You’ll bump into Samson Oak, but he forgot to bring a gift.
Contain your disappointment and descend the slope. Who knows, maybe you’ll find something nice down below.
