Shield Specialist

You have trained to take advantage of a shield's versatility as a tool in battle. You gain the following benefits:

• You gain proficiency with shields as an Improvised Weapon.
• When you take the Attack action and are wielding a shield, you can use a bonus action to make a melee attack with the shield as an improvised weapon. This attack uses the same ability modifier as the primary attack. The weapon’s damage die for this attack is a d4, and it deals bludgeoning damage.
• While you are wielding a shield, other creatures provoke an opportunity attack from you when they enter your reach.
