Fearmonger

After much practising in the mirror, you gain a terrifying presence, that absolutely none can resist.

   -Features and traits you have, spells you cast and your intimidation checks that can cause the frightened condition ignore immunity to being frightened, and creatures have disadvantage on saving throws made against those effects.

   -Effects that would remove a frightened condition caused by you, require two uses to remove the frightened condition.

   -You gain proficiency in intimidation. Your proficiency bonus is doubled for intimidation checks.

   -While a creature is frightened of you, you may use your action to incapacitate that creature until the start of your next turn.
