Haunting Reaper

All Reapers have something in common, death. Whether their brush with death was fleeting or they have been returned to life by divine means, they are forever marked. Fighters with this martial archetype learn to harness this experience and turn it into a weapon. As a Reaper grows in power, they begin to resemble the fabled Grim Reaper.

Based on Andrew Ceasar's reaper subclass from their six halloween sub-class collection.

 

Reaper's Scythe

Starting at 3rd level, you use death’s power to conjure a scythe black as night that trails wisps of ethereal energy in its wake. As a bonus action on your turn you create a scythe. The scythe deals 1D12 Slashing or Radiant damage and has the two-handed and heavy properties. The scythe disappears if it leaves your hands.

Ethos of the Dead

Starting at 3rd level, you are empowered by the death of those around you and use it to ravage your enemies. Whenever you kill a creature, you gain a point of Ethos. You can have a maximum number of Ethos points equal to your proficiency bonus. Once per turn, when you hit a creature with a melee attack, you can expend 1 point of Ethos to deal an extra 2D6 Radiant damage to the target. Every point of Ethos spent beyond the first adds an additional 2D6 damage. At lv 10 the damage increases to 4d6

Reaper's Sense

Starting at 7th level, you can hear the reaper calling. As a bonus action, you can study a creature within 30 feet and determine if it’s above or below half Hit Points. In addition you can see invisible creatures within 30 feet of you as long as they are under half Hit Points.

Reaping

Starting at 10th level, each point of Ethos you expend deals 4D6 Radiant Damage, and when hitting a target your scythe prevents regeneration until the start of your next turn.

Wings of the Reaper

Starting at 15th level, you can sprout massive bone wings from your back and take flight. As a bonus action, bone wings erupt from your back, and you gain a Fly Speed equal to your Movement Speed. You can dismiss the wings as a bonus action.

Grim Reaper

Starting at 18th level, you become the very essence of death and assume the form of a grim reaper. As a bonus action, your form shifts as you are cloaked in black robes and your face takes on the visage of a skull. While in this form you gain several benefits. You gain three points of Ethos. Only while in this form may your Ethos exceed your Proficiency bonus. Whenever a hostile creature is reduced to 0 Hit Points within 10 feet of you, you gain temporary Hit Points equal to twice your level plus your Constitution modifier. Spending a Point of Ethos deals 6D6 Radiant Damage. This Form lasts for 1 Minute. Once you use this feature, you can't use it again until after you finish a long rest.
