Gain expertise in the Acrobatics skill. You gain a climbing and a swimming speed equal to your movement speed and take half damage from falling. You also use your Dexterity to calculate your jumps, instead of Strength. If you have the Cunning Gambit feature you may learn the Porch Climber Gambit without it counting towards the number of gambits you have learned.
Running Jump
You can make extremely high jumps. When you Dash, you gain a flying speed equal to your movement speed, until the end of this turn.
