Ironbreaker

Your people defied the titans and giants. Unity has sustained them, and tenaciousness has upheld them; traditions preserving these values serve them well. They stand unmoved and unconquered, like the mountains, against orcs and goblins and dragons. When the enemy forces are composed of little more than savages, dwarven armies break them like stone channels water

Defensive Stance

When you choose this archetype at 3rd level, you learn to become a stalwart bastion of defense. On your turn, you can enter a Defensive Stance as a bonus action.

While in a Defensive Stance, you gain the following benefits while you are using a shield:

You have advantage on Strength saving throws.

Hostile creatures treat the area within 5 feet of you as difficult terrain.

Your speed is halved.

Your defensive stance lasts for 1 minute. It ends early if you are knocked unconscious. You can also end your Defensive Stance on your turn as a bonus action.

You can use this feature a number of times equal to your Constitution modifier (a minimum of once). You regain all expended uses when you finish a long rest.

Tide of Iron

When you choose this archetype at 3rd level, you are able to use your shield to strike devastating blows against your opponents. You treat any shield you wield as a light martial weapon and gain proficiency with it. The weapon deals 1d6 bludgeoning damage.

Bastion of Defense

Starting at 7th level, your shield becomes an impenetrable wall of protection for your allies. While you are in your Defensive Stance, as a bonus action you can provide one-half cover to all creatures of your choice within 5 feet of you until the start of your next turn.

Hold the Line

At 10th level, you become a master of locking down your enemies. While you are in your Defensive Stance, creatures provoke an opportunity attack from you when they move 5 feet or more while within your reach, and if you hit a creature with an opportunity attack, the target’s speed is reduced to 0 until the end of the current turn.

Additionally, while in Defensive Stance, as a reaction you can add your shield’s AC bonus to a Dexterity Saving Throw and you gain resistance to bludgeoning, piercing, and slashing damage for 1 minute. Once you use this ability, you cannot use it again until you finish a short or long rest.

Stalwart Defender

Starting at 15th level, while you are in your Defensive Stance, you and friendly creatures within 5 feet of you gain +1 AC and reduce the distance they are moved by any pull, push, or slide by 10 feet.

Iron Will

Starting at 18th level, your unbreakable willpower allows you to grin and bear the weight of any assault. If you take damage that reduces you to 0 hit points and doesn’t kill you outright, you can use your reaction to delay falling unconscious, and you can immediately spend up to half your Hit Dice. You regain hit points equal to the total + your Constitution Modifier. Until the end of your next turn, you gain resistance to all damage.

Once you use this feature, you can’t use it again until you finish a long rest.
