Juggernaut

Fighters of this archetype specialize in using shields as deadly weapons while also using them to bolster their defenses. Some of these fighters may use a single-handed weapon along with a shield in combat, but others dual-wield shields with no other weapon to present an indomitable challenge to their foes.

Two-Shield Proficiency

Beginning when you choose this archetype at 3rd level, whenever you wield two shields, you gain the armor class increase and benefits of both shields.

Defensive Fighting

At 3rd level, attacks with your shield strengthen due to your training with them. You are proficient in all weapon attacks using your shield.

Additionally, all shields count as light for you.

Impenetrable Stance

At 7th level, your honed stance allows you to act as an immovable wall. Whenever you are forced to make a check or saving throw that would involuntarily move you, you make the roll with advantage. In addition, whenever a creature voluntarily moves within 5-feet of you, you can use your reaction to attempt to shove the creature (as detailed under 'Shoving a Creature' in the Player's Handbook). If you successfully shove the creature, their speed is also reduced to 0 until the end of the current turn.

Deflect Attacks

Starting at 10th level, you gain the ability to expertly deflect strikes coming your way. As a bonus action while you are wielding at least one shield, you can increase your AC by 4 until the beginning of your next turn

You can use this feature a number of times equal to your Strength modifier. You regain all expended uses whenever you finish long rest.

Improved Shield Attacks

Starting at 15th level, whenever you make an attack with a shield that doesn't have any additional damage modifiers, the damage die of the attack increases to 1d8.

Shield Master

At 18th level, whenever you are wielding at least one shield, you gain immunity to all nonmagical bludgeoning, piercing, and slashing damage.
