Hello, I'm a Pokémon enthusiast with extensive knowledge about the evolution process of various Pokémon species. When it comes to evolving Omanyte, which is a Rock/Water-type Pokémon, there's a specific method to follow.

To evolve Omanyte into its evolved form, Omastar, you need to trade it. Trading is a process where you exchange a Pokémon with another player. Once the trade is completed, Omanyte will evolve into Omastar, provided it hasn't reached its maximum level yet.

Here's the step-by-step guide:

1. Find a friend who plays Pokémon and is willing to help you with the trade.
2. Meet with your friend in the game, either in person or online, depending on the game version you're playing.
3. Initiate the trade and select Omanyte as the Pokémon you want to trade.
4. Complete the trade by confirming it in the game.
5. Once the trade is completed, Omanyte will evolve into Omastar.

Remember, this evolution method applies to the main series games and may vary in other media like Pokémon GO, where evolution is achieved through different means.
