Counter stance

When choosing a fighting style you can forgo choosing a fight style and choose these feat instead. You cannot acquire this feat by any other means. This Feat allows you to take the counter reaction once per a turn. As a reaction the user  must make a Dex save of 14 to use a melee weapon to deflect an enemy's melee attack. If the user passes the Dex save the user may make a weapon attack roll on the enemy you countered. If the attack against the user is made at advantage the user rolls  the Dex save at disadvantage. The attack roll made after a counter is at advantage if the attack countered was an unarmed strike.
