Jsk Duty of the Vanguard

Offensive Aegis
At 3rd level, you know that the best defence is a good offense. While you benefit from your Aegis feature, your weapon attacks deal additional damage equal to the damage reduction provided by your Aegis feature. This additional damage is not added to weapon attacks made using a shield.

Shield Bash
At 3rd level, a shield is just as deadly as any weapon in your hands. When you take the Attack action, you can use your bonus action during the same turn to make a melee weapon attack using your shield, which you are proficient with. Your shield deals 1d4 bludgeoning damage, and you can use your Strength or Dexterity modifier for the attack and damage rolls of your shield. On a hit, you can deal damage or you can push the target 5 feet (your choice). When you make an opportunity attack, you can use your shield instead of a weapon, causing the slow condition on a hit.
