Obnatus Metus

Beginning at level 13, you have learned to use your dreadful reputation as a weapon. When you are within 30 feet of a creature, and there are no other creatures within 30 feet of that creature, you can, as a bonus action, force it to succeed a Charisma against your Sicarius save DC. On failure, that creature becomes frightened of you for 1 minute. While that creature is frightened of you, you can add your Intelligence modifier to any Wisdom(Insight) checks made against that creature.

The creature can repeat it's saving throw every time it is harmed, ending the frightened condition on success. You can only use this effect once per long or short rest.

At level 17, you gain advantage on Wisdom(Survival) and Intelligence(Investigation) checks made to track a creature that has the poisoned effect.

Additionally, after you hit a creature for the first time, you can force it to make a Wisdom saving throw against your Sicarius saving DC. On failure, your next attack against the creature deals double damage. You can only use this part of the feature once per long rest.
