Doom Knight

You have trained hard and brutally each day, honing your skills to become an unstoppable force of Hellish wrath. You may be good. You may be evil. But one thing is constant, a mantra that echoes in the minds of all Doom Knights. Rip and Tear, Until It's Done.

Level 3: Hellish Arsenal

During a long rest, choose up to two weapons you have mastery with, choose a property from the list to give them. This property disappears after a short rest.

.Chainsaw. Your blades are extremely brutal and effective, ripping up enemies as soon as you land an attack. A weapon with this property crits on a 19 or 20 and adds an additional damage dice if it crits.

.Combat Shotgun (ranged weapons only). A ranged weapon with this property will have its range shifted to be a 40 ft cone, you can add an extra 2d8 of damage if the attack lands.

.Crucible. Your weapon becomes superheated, adding on to their damage. A weapon with this property can be heated up as a bonus action, adding an extra 3d6 fire damage to damage rolls until you go a turn without hitting anything.

.Doom Blade (Swords only). A weapon with this property becomes jagged and retractable. Drawing or stowing this weapon only takes a bonus action, along with it dealing an extra 1d4 piercing damage (3d4 if the weapon scores a critical hit).

.BFW 9000. A weapon with this property gains the heavy and two handed properties, as well as dealing an additional 1d6 of its damage type plus 4 charges. You can expend these charges to add an extra 1d6 lightning damage to your next attack with this weapon.

At level 10 you can give 3 weapons a different property. At level 15 you can choose 4.

Level 7: Brutal Kill

If an enemy is below a certain amount of HP (3 x your fighter level + strength score), prone and you are within 5 feet of them, you can use your action to unleash an attack of pure brutality, a powerful combo that causes pure bloodshed. This attack instantly kills and tears the enemy to shreds. You cannot use this feature again until you finish a long rest.

Level 10: Bloodied Strength

Upon using your Brutal Kill ability, you fill yourself with the power of that spilt blood, you can choose an option from the following list for what effect you gain.

.Berserk. After using your Brutal Kill, you become filled with raging fury, for the next minute, you make attack rolls with disadvantage, but add +10 to all damage rolls. This increases to +15 at level 15,

.Seek and Destroy. The strength gained from your Brutal Kill has increased your senses and tracking abilities, for the next minute you have advantage on all perception checks and gain a +5 to attack rolls. This increases to +10 at level 15.

.Blood Fuelled. After using your Brutal Kill, the bloodshed grants you immense speed and vigor. For the next minute, your speed increases to 50 ft and you gain 20 temporary Hit Points. This increases to 25 temp HP at 15th level.

.Armoured Offensive. After you use your Brutal Kill, the blood spilt fills you with powerful fortitude. For the next minute, you gain a +3 to your AC as well as advantage on saving throws.

Level 18: The Only Thing They Fear Is You

At 18th level, you now are a walking destroyer for all enemies. If a creature of CR 5 and below falls prone and is within range of your melee weapons, you can instantly Brutal Kill it for free (A creature killed by a free Brutal Kill does not grant the bonus from Blood Fuelled)

Level 18: Rip and Tear

As you swing your weapons and carve through your enemies, you fill yourself with the strength of their demise, continuing your relentless slaughter of enemy forces. If you use your Action Surge and it kills an enemy, you may regain a use of Action Surge. This ability is only usable twice per long rest.
