Dwarven Warrior

Dwarven Warriors are either Dwarves themselves or they learned from the best fighters in their strongholds. A Dwarven Warrior's bravery is unbreakable, and they have utmost confidence in their strength. The only question one might have time to ask when fighting one of these warriors is which of the two is bigger, their beard or their hammer.

Dwarven Protection

Beginning at 3rd level you learn the shielding techniques of the Dwarves, and use them to protect yourself better than anybody could normally. When using a shield, increase the AC bonus by 2 points. Also when in melee combat with an enemy that is your size or smaller, you can use your shield as an improvised weapon that on a hit (In addition to any damage) pushes the target 5 feet in a direction of your choice.

Dwarven Arrows

At 7th level, you master throwing light hammers, and can use them with ease. When throwing a light hammer, change the damage dice to 1D8. Also when throwing a light hammer, add 2 to the hit roll.

Stunning Hit

At 10th level when using a weapon that deals bludgeoning damage, on a critical hit after calculating damage, the enemy is stunned until the end of your next turn.

Heavy Charge

Starting at 15th level when you move at least 10ft in any direction and also wearing heavy armor, you can force any creature in your path as long as it is your size or larger to make a Strength saving throw. The DC for which is equal to 8 + Your Proficiency Bonus + Your Strength Modifier.

Battle Cry

Starting at 18th level Once per long rest as a bonus action you can scream out a battle cry that increases the hit points of all friendly creatures within 30ft to half of their hit point maximum (rounding down) (This has no effect if they are at or above half their hit point maximum already).

Bug

D&D beyond currently has a bug which requires all custom fighter classes to have a 5th level feature despite there being no such feature in official material. Please know this is not part of the class.
