Art of the Flash Step

You've mastered the art of measured steps and lightning speed, allowing you to devastate your enemies before they've even noticed they've been hit.

Flash Step Attack. Once per turn, you can choose to commit to a Flash Step Attack as an action, turning the space you currently occupy into your Flash Step Point. Choose a creature within your movement range and instantly move to an unoccupied space within 5ft of them, then make one melee attack against them. On a hit, choose a different creature within your current movement range and instantly move to an unoccupied space within 5ft of them, then make one melee attack against them. You cannot choose a creature that you have already attacked with Flash Step Attack this turn. Whether this attack hits or misses, you instantly return to your Flash Step Point and Flash Step Attack will no longer be active.

While Flash Step Attack is active, your movements are too fast to trigger Attacks of Opportunity or trigger any other effects dependent on sensing you.

Once used, all of your movement is consumed regardless of any remaining movement or other effects that grant additional movement. Flash Step Attack can be used a number of times equal to your Proficiency Bonus, recharging all uses on a Long Rest.

Upgradeable. This feat can be taken a second time to increase the number of creatures you can attack by 1, and the number of attacks you can make by 1.
