Deviating Rage

Two Rounds after you frenzy you may activate this ability and your rage and adrenaline begin to boil so hot and so mindlessly that you begin to pay less attention to attacks towards you. Every time you are hit the rage takes more and more of your body over and you begin to add +1 to your AC each time. This applies only if your natural AC is below a 17 and this feature can only be used once per long rest.
