When you reach level 3, you commit yourself to the Grim Reaper. The path grants you features at 3rd, 6th, 10th, 14th.

Reaper's Retribution

While raging, you gain a bonus to the damage you deal on your first attack each round on any enemy within 10 feet of you. This damage equals 1/4 of your missing Hit Points (i.e if you have 20 Hit Points missing you will deal an extra 5 damage on your first attack each turn).

Throw Caution to the Wind

Beginning at 6th level, you learn how to draw additional power from your body when you are wounded. As an action on your turn, you can boost your Strength Score by 4 points for 1 minute as long as you are not at max Hit Points. At the end of the minute, you lose half of your Hit Points. If this would drop you to zero you fall unconscious at the end of the minute. Normal rules for death saving throws and death conditions still apply. Once used you must take a long rest to regain expended uses.

Reaper's Laugh

After killing your foe, you can use a bonus action and do a Strength(Intimidation) Check to scare the shit out of your opponents that are 30 feet away. If it can see and/or hear you, it must succeed on a WIS saving throw (DC {{savedc:cha}} or be frightened until the end of your next turn. If the creature succeeds on its saving throw, you can’t use this feature on that creature again for 24 hours.

You gain proficiency in the Intimidation skill. If you are already proficient in this skill you can double your proficiency bonus with it.

Last Resort

As a last ditch effort, you throw everything you have into one blow. As an action, you can make an attack that deals additional damage equal to half of your missing Hit Points (i.e if your HP maximum is 180 and you have 20 health you will deal an additional 80 points of damage) Once this action is taken you immediately fall unconscious and begin rolling Death Saving Throws. Once this ability is used you must take a long rest to recharge it.
