These changes will hopefully help this subclass better define itself and synergize with its other abilities.

Dreadful Surge

When you choose this archetype at 3rd level, you learn how to inspire fear in your enemies.

When you use your Action Surge feature, all creatures you choose within 15 feet must make a Wisdom saving throw (DC = 8 + your proficiency bonus + your Constitution modifier). Creatures that fail this save are frightened, and make a Wisdom saving throw at the end of their turn to remove this effect.

Emissary of Fear

At 7th level, you gain proficiency in the Intimidation skill. In addition, your proficiency bonus is doubled for any ability check you make that uses Intimidation. You also gain advantage to Wisdom saving throws.

Resurgence

At 10th level, you are especially hard to kill, a true knight of fear and conquest. When you use your Second Wind feature, you gain temporary hit points equal to the health healed, and until the end of your next turn all attacks have disadvantage to hit you.

Implacable

Starting at 15th level, your enemies cannot deny your dreadful power. If you would roll with disadvantage on an attack roll or skill check, roll without disadvantage instead.

Iron Will

Starting at 18th level, even the mightiest of magics shatter against your unbendable will. You have advantage on saves against spells and other magical effects.
