Volcarona:
1. Obtain a Larvesta: You can find Larvesta in the Lostlorn Forest, but it's very rare. It's a roaming encounter, so you'll need to keep running into random encounters until you find one.
2. Level up Larvesta: Larvesta evolves into Volcarona at level 59. This will require some dedicated grinding.
Scolipede:
1. Obtain a Venipede: Venipede can be found in various locations throughout the game, including Pinwheel Forest, Relic Passage, and Undella Bay.
2. Evolve Venipede: Venipede evolves into Whirlipede at level 22 and then into Scolipede at level 30.
Tips for finding rare Pokémon:
* Use the Poké Radar: This item, obtained from the Pokémon Ranger in Undella Bay, helps you find Pokémon in a specific area. When it vibrates, there's a chance a rare Pokémon is nearby.
* Use the "Sweet Scent" move: This move attracts Pokémon in a small area, increasing your chances of encountering the Pokémon you're looking for.
* Explore different areas: The Pokémon you're looking for might be found in specific areas at specific times of day.
* Be patient: Finding rare Pokémon like Larvesta can take time. Don't get discouraged!
Remember: While Volcarona and Scolipede aren't "legendary" in the traditional sense (like the Pokémon found in legendary events), they are both very powerful and sought-after Pokémon due to their unique typing and stats.
