Cursed Strikes

When you use Cursed Strikes, the cursed creature takes additional necrotic damage equal to your proficiency bonus. Additionally, the curse is not limited to a single target; you can choose a number of creatures equal to your Strength or Dexterity modifier (whichever is higher) within 30 feet to be affected by the curse.

Hexed Defense

Your connection to curses enhances your defensive capabilities. When a creature cursed by your Cursed Strikes makes an attack against you, you can use your reaction to gain a bonus to your AC equal to your proficiency bonus against that attack.

Cursed Retribution

When a creature under the effect of your Cursed Strikes feature damages you with a melee attack, it takes necrotic damage equal to your proficiency bonus. This damage increases to 2x your proficiency bonus at 18th level.

Cloak Of Shadows

You can shroud yourself in a cloak of magical shadows. As a reaction when you are targeted by an attack, you can impose disadvantage on the attack roll. You can use this feature a number of times equal to your Dexterity modifier (minimum of 1) and regain expended uses after finishing a long rest.

Darkened Fury

Your fury in battle now unleashes the full power of shadows and curses. When you use your Action Surge, your attacks deal an additional 2d6 necrotic damage, and creatures hit by your attacks have their movement speed reduced by half until the start of your next turn.
