Defensive Combatant

Shielded Combatant
When using a shield as an improvised Weapon, you may do the following:

• Use a d6 for damage rolls to make a one handed attack. You are proficient with attack rolls made in this way, and the shield becomes a weapon with the finesse and light property. 
  Doing so reduces your armor class by 1 until the beginning of your next turn. This attack does bludgeoning damage.
• When you make a weapon attack that uses one hand, you may make another using the shield as a bonus action.
• When an enemy attack misses you by more than 5, you may use your reaction to make a single weapon attack against them with the shield, if they are within range to do so without moving.
