LAX FAQs
What does the Lax nature do in Pokemon?
Lax raises Defense 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 Lax nature prefer Sour flavor and dislike Bitter.
What are the best Lax nature Pokemon?
Top Lax users include Mawile, Nymble, Dunsparce, and Wynaut. They benefit from the Defense 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 Lax a good nature for competitive Pokemon?
Lax is a strong competitive nature. It fills a solid niche for defensive builds. The key is matching it to Pokemon that don't need Sp. Defense in their moveset.
How do I get a Lax nature Pokemon?
Synchronize is the fastest method. Lead with a Pokemon that has Synchronize and Lax nature, and wild encounters match it (Gen 3+). Breeding works too: give the Lax parent an Everstone and all offspring inherit the nature. Nature Mints (Gen 8+) let you change the stat effect to Lax without rebreeding.
Should I use Lax or Impish?
Lax prioritizes physical mixed defense, while Impish goes for dedicated physical wall. Pick Lax when your Pokemon's role depends on the stat it boosts. Go with Impish when dedicated physical wall matters more for your team.
