Graceful Athlete

You can use your lean, agile body to scale tall heights. Add your Dexterity modifier instead of your Strength bonus to Climb and Swim checks. If you have a Strength penalty, you must apply both your Strength penalty and your Dexterity modifier. This feat grants no benefit to creatures that already add their Dexterity modifier to Climb and Swim checks (such as all Tiny or smaller creatures). Special: Investigators, rogues (including unchained rogues), and slayers

Prerequisites

Acrobatics 1 rank, Climb 1 rank, Swim 1 rank, racial bonus to Dexterity.
