Echo’s Protection

At Level 5 - When an enemy takes an attack action against an ally you can see within 40 ft of you, you feel your Blink abilities going into overdrive. You can then take a reaction to blink in between them and the attack, imposing disadvantage on the attack. If the attack still hits, you take the damage they would have, using the AC of the person you are defending. You may use this feature a number of times equal to your proficiency bonus, and you regain its use after completing a long rest.
