Path of the Executioner

You have become one with the blade. Every swing of your heavy weapon comes down with greater and greater force, slowly but surely chipping away at your enemy. As you kill more and more their souls become pulled into the blade and shroud you in ghostly mist.

Emboldened Critical

Beginning when you choose this archetype at the 3rd level, your weapon attacks score a critical hit on a roll of 19 and 20 while raging.

Additionally, you gain the uncanny ability to announce your profession by body language and gait alone. You gain proficiency in the intimidation skill, unless you are already proficient in it, in which case you gain expertise or proficiency in any skill of your choice.

Marked for execution

At 6th level you are able to mark a creature for death equal to how many times you can rage and can be replenished on a long rest. When you enter Rage you may call out a creature who can hear and see you within 60 feet. Once you have done that, they will have been marked to be executed. After this effect has been applied you enter a rage. This effect lasts 1 minute. If the target drops to 0 hit points before this effect ends, you can use a bonus action on a subsequent turn of yours to mark a new creature. Every creature who has seen or heard you do so will have the following benefits against that one creature:

You or an ally can gain a d4 to try and change a miss into a hit or add 1d4 to your damage on a successful hit
Only applies to weapon attacks and can only be applied to once per round

Additionally after marking the creature, it must make a wisdom save against your save DC (8 + proficiency bonus + strength) or become frightened for the duration of 1 minute. This requires no action.

Harbinger of Death

At 10th level your weapon becomes infused with death itself. While raging you may apply a bonus to damage rolls made with melee weapons and unarmed strikes equal to double your proficiency bonus. This damage is necrotic and reduces the hit point maximum by the amount of damage dealt.

Execute

You are a ruthless killer, after killing an enemy your turn resets. This allows all of your actions to reset and any turn based effects are also extend, but for one round. You immediately take the dash action for no action cost.
