RASH FAQs
What does the Rash nature do in Pokemon?
Rash raises Sp. Attack by 10% and lowers Sp. Defense by 10%. At level 100 with full investment, that's roughly a 30-point swing on the boosted stat. Pokemon with Rash nature prefer Dry flavor and dislike Bitter.
What are the best Rash nature Pokemon?
Top Rash users include Salamence, Raikou, Horsea, and Nidoking. They benefit from the Sp. Attack boost because their main damage comes from that stat. The Sp. Defense drop doesn't hurt them since they don't rely on it.
Is Rash a good nature for competitive Pokemon?
Rash is a strong competitive nature. It's one of the most-used natures in competitive formats. The key is matching it to Pokemon that don't need Sp. Defense in their moveset.
How do I get a Rash nature Pokemon?
Synchronize is the fastest method. Lead with a Pokemon that has Synchronize and Rash nature, and wild encounters match it (Gen 3+). Breeding works too: give the Rash parent an Everstone and all offspring inherit the nature. Nature Mints (Gen 8+) let you change the stat effect to Rash without rebreeding.
Should I use Rash or Modest?
Rash prioritizes mixed offense, while Modest goes for dedicated special. Pick Rash when your Pokemon's role depends on the stat it boosts. Go with Modest when dedicated special matters more for your team.
