Finishing Blow

You gain the following benefits.

Ability Score Increase. Increase your Strength score by 1, to a maximum of 20.

Coup de Grâce. When you deal damage to a creature using an attack with a Melee weapon or Unarmed Strike and leave it with a number of hit points equal to or lower than twice your level, you reduce that creature to 0 hit points instead. 

Follow Through. When Finishing Blow activates for the first time on each of your turns, you can make an additional attack with the same weapon against another target within range.
