Every nature is a flat trade: +10% to one stat, −10% to another (never HP). Five natures are neutral. Picking the right nature is the cheapest damage boost or speed tier jump in the game.

The nature multiplier applies to the final stat after base stat, level and investment — so it's worth more on stats you've invested in. Compare Adamant vs Jolly damage and speed outcomes directly in the calculator: set the nature dropdown and watch the rolls change.
