Boon of Terror

Boon of Terror
Feat
Prerequisite: Level 19

You gain the following benefits.
Fearless.
You have Immunity to the Frightened condition.
Flee, Fools!.
When a creature with the Frightened condition starts its turn within 60 feet of you, you can take a Reaction to stoke its terror, provided you can see the creature and it isn't behind Total Cover. If you do so, the creature must succeed on a Wisdom saving throw (DC 8 plus your Charisma modifier and your Proficiency Bonus) or spend its turn moving away from you by the fastest available means. Once you use this benefit, you can't use it again until you finish a Short or Long Rest.
Intimidating.
You gain Proficiency in the Intimidation skill if you don't already have it. You also gain Expertise in Intimidation.
