The Harrow

Your patron is a mysterious entity who whispers vicious secrets into your ear, carried by the howling wind or whistled by a pure-white shrike. The being craves terrible vengeance for sleights of all forms and enlists any who are willing to listen to the dark voice on the breeze. The Harrow encourages its warlocks to render their revenge through a combination of subterfuge and overwhelming brutality, many a ruler who considered themselves untouchable have been found impaled on a bed of thorns

Traumatize

Starting at 1st level, your thirst for vengeance drives you to seek psychological vulnerabilities in your prey. When you damage a creature, you can force it to make a Wisdom saving throw against your warlock spell save DC. A creature that fails this saving throw is frightened by you for 10 minutes. At the end of each of the creature's turns, it can repeat the saving throw, the effect ending on a success.

Once you use this feature, you can’t use it again until you finish a short or long rest.

Rend Mind

Starting at 1st level, you can use your mastery of psychological warfare to inflict additional damage to creatures you're emotionally dominating. Whenever you damage a creature that is charmed or frightened by you, you can add your proficiency bonus to the damage.

Vengeful Strike

Starting at 6th level, you can channel your cold, seething rage to lash out at a being that dares strike you. When a creature within 5 feet of you targets you with an attack, you can inflict cold damage on that creature equal to half your warlock level.

You can use this feature a number of times equal to your Charisma modifier (a minimum of once). You regain any expended uses when you finish a long rest.

Revel in Terror

Starting at 10th level, your mastery of invoking terror in others has totally numbed you to fear. You are immune to being frightened. You have resistance to damage from creatures who are frightened and when a hostile frightened creature you can see is reduced to 0 hit points, you gain temporary hit points equal to your warlock level.

Grim Determination

Starting at 14th level, your thirst for vengeance propels you beyond the grasp of death. When a creature reduces you to 0 hit points, you may place a baleful curse of vengeance on the creature who last damaged you this turn and gain temporary hit points equal to 5 × your warlock level for 1 minute, after which time you lose all temporary hit points granted by this feature. As long as you have these temporary hit points you do not fall unconscious at 0 hit points and you are considered stable. If you lose all these temporary hit points and you're still at 0 hit points you immediately fall unconscious and begin dying. The curse ends early if you lose all the temporary hit points granted by this feature. Until the curse ends, cursed creatures suffer the following effects:

• Vulnerability to damage from your attacks, spells, and features
• Disadvantage on saving throws against your spells
• Whenever the creature tries to attack you for the first time on a turn, the attacker must make a Wisdom saving throw against your spell save DC. On a failed save, it can’t attack you on this turn, and it must choose a new target for its attack or the attack is wasted.

In addition, when you kill a cursed creature, you regain half your maximum hit points.

Once you use this feature, you can’t use it again until you finish a long rest.
