Path of the Slayer

Run, run when their eyes lock on you, for it is your only hope of salvation. Slayers take no mercy, and instead give in fully to the sheer brutality of combat, gutting, beheading, and crushing, the more brutal the fight, the more fierce they strike. They shoot fear deep into the hearts of the enemy, and in turn bolster those who are behind them, if not simply for the fact they are grateful to not be the prey of this warrior. 

Brutal Finisher

Starting at 3rd level, upon slaying an enemy, you can use your Bonus Action to kill them in a spectacular fashion and strike fear into the hearts of its surrounding allies. In an Aura of 10 feet around the slain enemy, all hostile creatures must make Wisdom saving throws (DC equal to 8 + your proficiency bonus + your Strength modifier) or become frightened of you until the end of your next turn. The range of this aura increases to 30ft at 10t level, and at 15th level, creatures who fail the saving throw by more than 5 are stunned until the end of your next turn. ( An enemy is immune to this effect if it can’t see or hear you. Creatures immune to the frightened or stunned conditions are not affected)

Masochistic Rage

Starting at 3rd level, pain only sees to further your rage and hunger for carnage. As a character, severe pain is an encouragement to fight harder and push farther. Additionally, as you take damage, you build up a retribution score equal to half the damage you have received. While raging, when you make an attack, you can choose to add your retribution score to the attack's damage roll. This resets the retribution score to 0.

Ferocious Physique

At 6th level, your body has been honed into an instrument of carnage and power. Your presence alone is intimidating and you have further harnessed your own capabilities. You gain proficiency in Intimidation and acquire the Powerful Build Trait. You count as one size larger when determining your carrying capacity and the weight you can push, drag, or lift.

Make them an Example

Your fearlessness and vigor in combat has gone on to further encourage your allies around you. While raging, you can't be frightened. If you are frightened when you enter your rage, the effect is suspended for the duration of the rage. Additionally, as an action, you can make an example out of a dead enemy. Cut off their head, kick their corpse from a cliff, raise it into the air, show your allies that you are winning, and that victory is within your grasps. (You can only do this once per corpse.) All allies within 60 feet gain Immunity to being Frightened and temp hit points equal to your Intimidation modifier. 

Slay the Cowards

Starting at 14th level, frightened creatures within 30 feet of you have their movement speeds halved and you gain advantage on attack rolls against frightened creatures. Additionally, while raging your movement speed increases by 10 feet per slain enemy while raging to a max of 30 feet. This number resets once your rage ends.
