You can reposition yourself after a foe’s missed swing.
Prerequisites: Dex 15, Mobility or trick attack class feature.
Benefit: Whenever an opponent misses you with a melee attack, you can take a guarded step as a reaction, as long as you remain within that opponent’s threatened area. If you take this step, you can’t take a guarded step during your next turn. If you take an action to move during your next turn, subtract 5 feet from your total movement.
