• Brutal Effort. When you roll damage for a melee weapon attack, you can reroll the weapon’s damage dice and use either total.

Brutal Threat - Active Ability (Attack)

• When you take the Attack action on your turn, in place of taking an attack, you can summon your killing intent to issue a dire threat to a creature that can see or hear you within 60 feet. The target must make a Wisdom saving throw.
• On a failure, they become frightened for 1 minute. If it fails by 5 or more, it becomes frozen in terror, suffering the paralyzed condition while it is frightened. A frightened creature can repeat its saving throw at the end of each of its turns, ending the effecton success (if it fails by less than 5 it can end the paralyze effect, but annot become paralyzed after the initial save).
• If you kill a target while it is frightened in this way, you can repeat this action as a reaction targeting another creature within 30 feet that can see or hear you bypassing the usual usage restriction of the feature.

Once you use this feature, you cannot use it again until you complete a short or long rest.
