# Martial Archetype: The Iron Knight
The Iron Knight is a juggernaut, striding across the battlefield without fear. Clad in iron they stand unwavering in the fires of battle and they carry within them the strength and resolve to strike down their foes. Steadfast defenders and powerful warriors, the Iron Knight is a force to be reckoned with.
### Steadfast
When you choose this archetype at 3rd level, when a spell or other effect you can see (such as a trap or a dragon's fire breath) would force you to make a Dexterity saving throw you can instead make a Constitution saving throw to resist the effect.
### Heavyweight
Also at 3rd level, while you are wearing heavy armor you have advantage on ability checks and saving throws to avoid or escape being grappled, shoved, restrained, or otherwise moved against your will.
### Shield Slam
At 7th level you are adept at turning a strong defense into a powerful offense. You gain a +1 bonus to your AC while wielding a shield and when you take the Attack action, you can replace one of your normal attacks with a slam attack using a shield you are wielding. Make a melee weapon attack, dealing bludgeoning damage equal to 1d6 + your Strength modifier on hit, also on a hit the target must make a Strength saving throw (DC= 8 + your Strength modifier + your proficiency bonus), falling prone on a failure. Creatures that are more than one size category larger than you automatically succeed
### Unyielding Constitution
Starting at 10th level, your body and mind have hardened to resist the perils of battle. Your hit point maximum increases by 10 and increases by an additional 1 for every additional level you take in this class, and you have advantage on saving throws to resist being frightened, paralyzed, poisoned, or stunned.
In addition, when you are subjected to an effect that allows you to make a Constitution saving throw to take only half damage, you instead take no damage if you succeed on the saving throw, and only half damage if you fail.
### Sweeping Blows
At 15th level, none are safe from your attacks, even when they aren't the initial target. The first time on your turn when you hit a creature with a melee weapon attack, all other creatures of your choice within 5 feet of the original target and within your reach take damage equal to half of your damage roll.
### Bastion of Iron and Steel
At 18th level you are an indomitable juggernaut. While wearing heavy armor you have resistance to all nonmagical damage as well as magical bludgeoning, piercing, and slashing damage, and you can not be moved against your will as long as you are conscious and not incapacitated.
