Path of the Dying

 Maybe one day you made a god hate you by killing all of his followers, maybe a Lich tried to curse you because of fear, or maybe your anger was so strong that it became a curse to whoever showed in your path. Don't matter the origin, the only thing you know next was that your blade was glowing in dark energy and humans were raising of the ground without skin. 

 You can now feel the death in the battlefield, you know the hate of the soldiers, the fear of the villagers and the despair of the ones that face you head on. You're connected to the other world, to the feelings, and to death. Maybe people even dare to say that you're death itself or some type of plague. 

Rage of the Cursed

 It hurts, the feelings of death, there's no way someone would feel that and still sane. Starting at 3th level you can't be affected by any mind-affecting spell. You also gain the ability to do additional damage to Undeads based of your STR modifier and you gain additional AC when Undeads are attacking based on your CHA modifier. 

Cursed Blade

Starting at the 6th level you gain the ability to deliver curses using your blade. While in Rage, your weapon starts to evoke a dark cursed energy and whoever touch it, becomes cursed. The curse is random and is decided by rolling a 1d6 and can be only be used once for enemy.

Monster of Insanity

At the 10th level while in Rage you can choose one Undead trait to use for 1d4 turns, partially becoming that kind of undead. At this point you have accepted and mastered the bad feelings that people and creature can feel and so you can control those feelings, moving whatever the target is feeling to rage. You can choose one creature within 30ft of you to gain the ability to Rage for a turn, be it ally or foe.

Apprentice of Death

Starting at the 14th level you gain the ability to raise dead.
