Commander Black Skull

Any ability that involves raising the undead or controlling the dead does not effect the Commander Black Skull

Commander Black Skull can attack 3 times with a weapon of their Choice (DM's can choose what weapon they have, having a +8 to any weapon they use, not dependant on whether or not being proficient in that weapon)

Two-Weapon Fighting

When you take the Attack action and attack with a light melee weapon that you're holding in one hand, you can use a bonus action to attack with a different light melee weapon that you're holding in the other hand. You don't add your ability modifier to the damage of the bonus attack, unless that modifier is negative.

If either weapon has the thrown property, you can throw the weapon, instead of making a melee attack with it.

Fighting Style: Protection

When a creature you can see attacks a target other than you that is within 5 feet of you, you can use your reaction to impose disadvantage on the attack roll. You must be wielding a shield.

Call To Arms. With nearly all your troops gone, you call your brothers in arms to your aid and fight alongside you. When only one Black Skull Trooper is on the battlefield, dependant on how many Commander Black Skull, 1d4 Black Skull Troopers are called onto the battlefield.
