Fearful Force

You have become a force of terror in battle and gain the following benefits:

• You have advantage on attack rolls against frightened creatures.
• Creatures that can see you have disadvantage on saving throws made to end the frightened condition on themselves.
• When you score a critical hit or reduce a creature to 0 hit points, any creature within 30 feet of your original target must succeed on a wisdom Saving Throw or become frightened of you for 1 minute. The DC for this Saving Throw is 8 + your proficiency bonus + your Strength or Charisma Modifier (your choice when you gain this feat).
