Chapter 168 - 168: Return to Saffron City
Actually, the method Cain mentioned for temporarily modifying Metang's ability is to have a Pokémon that knows both the moves Role Play and Skill Swap.
Additionally, a Pokémon with the Light Metal ability is needed to make this work.
The move Role Play allows your Pokémon to copy another Pokémon's ability, while the move Skill Swap swaps your Pokémon's ability with that of another.
Thus, with a Pokémon that has the Light Metal ability and another that knows both moves, you can make Metang temporarily acquire the Light Metal ability.
However, having a Pokémon that knows both Role Play and Skill Swap is very difficult, as these moves are not available through TMs, meaning they can only be learned through tutoring or as egg moves.
This is a type of move combination, and Cain doesn't know how many people in this world are aware of this combination, as, from his past life until now, he has never seen anyone use it.
"So, let's exchange contact information. I need to discuss it with my master," Cain said, inventing a fictional master.
However, this was necessary to conceal that he could produce high-level Pokéblocks and also to make a good amount of money.
Since Cain said this, Steven gladly agreed, took out his phone, and they exchanged contacts.
After all, Pokéblock production isn't something that can be completed in a day or two, especially high-level custom Pokéblocks, which require extensive adjustment and testing before they're ready to use.
"I can provide all the materials, and I'll cover all research costs during the process. Once the Pokéblocks are made and meet my requirements, I'll pay you according to the standard market rate," Steven said with a smile.
