The Nihilist

Followers of the path of nihilism have been exposed to some great epiphany that all things in life are meaningless. You have stared into the open maw of the abyss and found nothing. In an absolute meaningless existence you discovered an odd co-existence between power and oblivion. There is no meaning to life, morality, or social norms. Only you can see absolute futility of it all and it has granted you the freedom to chart your own course. Followers forsake gods, hope, morality, and immorality as useless trinkets of a doomed existence. 

Arcane Dysfunction

Beginning at 1st You gain advantage on saving throws versus spells. You view divine or arcane power as meaningless and ineffective. Thus you have forsaken any power that is not derived of the oblivion for which we are all bound.

Nullification

Beginning at 6th level you are resistant to damage caused by spells. Your resistance is granted by your knowledge that divine or arcane forces will ultimately be consumed by the void of meaninglessness.

Nihilistic Resolve

Beginning at 10th level you cannot be swayed by emotional extremes. You are immune to the Charmed and Frightened conditions. What is there to fear when ultimately even eldritch horrors will fade from this pointless charade? What is there to love when it will inevitably be swallowed by the endless void?

Tour of Oblivion

Starting at 14th level, as an action you may select a target within 60 feet of you. The target must succeed on a DC 8 + CHA Modifier + Proficiency bonus saving throw. If their alignment is Lawful the save is made at disadvantage. The target is given a mental view of oblivion and all it has to offer and is stunned until the end of your next turn.

At the end of your next turn, If the target is not undead, it takes 10d10 psychic damage as it reels from it's view into it's meaningless existence.

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