Jsk Feats:Reflex Fighter

You are especially swift in combat, and your reflexes are faster than the eye can see.
 * You gain a +5 bonus to your passive Perception.
 * When you are surprised at the start of combat, you can use your Reaction to act normally on your first turn.
 * You can use your Reaction even if you have used your Reaction this round. You can use this ability a number of times equal to your proficiency bonus, and you regain any expended uses when you finish a long rest.
