Path of the Cursewrought: Final Edit

You have been riddled with curses, whose magics have seeped into your very being. Whether this corruption came from a vindictive cabal of witches, or as a result of your trespassing on forsaken grounds, you cannot escape the arcane darkness that dwells within you.
     Barbarians who follow the Path of the Cursewrought are outcasts, seeking either redemption and purification, or revenge. Through their fury, they have learned to transform their curses into weapons, spreading them like a pestilence to their enemies, and crushing all those who stand in their way.

RageCurse

Starting at 3rd level, whenever you hit a creature with a melee weapon attack while you're raging, you can use your bonus action to attempt to inflict a curse on the target. The target must make a Wisdom saving throw (DC equals 8 + your Constitution modifier + your proficiency bonus) or be cursed until your rage ends. This curse applies one of the following effects of your choice:

* The target's AC is reduced by 2 until your rage ends.
* Once on each of your turns, you can deal an additional damage dice of necrotic damage equal to your weapons damage die when you hit the target afflicted with your rage curse with a melee attack.
* The targets movement speed is decreased by 10ft.

A creature can only be affected by one of your curses at a time. If a creature succeeds the first save, they have adv on the next save against this curse.
     Starting at 10th level, a creature cursed by you also takes twice the amount of additional Rage Damage when you hit it with a melee weapon attack

Aegis Black

By 6th level, you possess a profound bulwark against darkness. You have resistance to necrotic damage, and have advantage on saving throws against necromancy spells and effects that would curse or possess you

FuryBane

Starting at 10th level, whenever you enter a rage, you can cast the spell bane (DC equals 8 + your Constitution modifier + your proficiency bonus) without using an action or spell slot. You can concentrate on this spell even while you're raging. 

At 14th level you can upcast bane at level 3

Spiteful Curse

At 14th level, when your hit by an attack with a melee weapon you can attempt to curse your opponent, using your reaction to cause the attacker excruciating pain or overwhelming fear, they must succeed on a Wisdom saving throw or be frightened by you until the end of their next turn. While frightened in this way the creature is paralysed. If the creature passes the save, it is immune to this effect for 24 hours
