Phobiast

A dark and foul character those who become masters of terror and fear, who decieve and contrive plots to cause mass panic and terror amongst helpless denizens. Those who follow this path leave fear in their wake as they skip from town to town, becoming a boogyman of the night. A perfect duty for those that enjoy spreading terror.

Swift Terror

Starting at 3rd level, you can use the bonus action granted by your Cunning Action to make a Charisma ([skill]Intimidation/skill]) check, using your ability to cause terror. You can target a creature and intimidate them, where they must make a Wisdom save contesting your Intimidation check or become frightened for 1 minute.

Professional Fear

When you choose this archetype at 3rd level, you gain proficiency with the skill Intimidation if you don't have it and gain advantage on wisdom saves against being Frightened.

Strike the Fearful Down

Starting at 9th level, you have advantage on attack rolls against creatures that are frightened.

Creatures that are immune to frightened can be frightened by Quick Terror, but have advantage on the wisdom save.

Feed off the Fear

By 13th level, your mastery over fear makes you hungry for more. You can frighten a number of creatures equal to your proficiency bonus with your Quick Terror ability, and you gain 3 temporary hit points that decay over an hour for each creature that is frightened of you. You gain 5 x your proficiency bonus temporary hit points whenever you kill a creature that is frightened of you.

Master of Horror

When you reach 17th level, you have become a master of horror, allowing you to manipulate the deepest terrors of both your victim, and your own mind. You gain immunity to the frightened status, and creatures you frighten have disadvantage on attack and saving throws regardless of whether your visible or not. You also deal an extra 2d10 necrotic damage whenever you frighten a creature with Quick Terror. You deal 4d10 necrotic damage when frightening creatures that are usually immune. This damage cannot be repeated on the same creature.
