While all monks seek unity with the cosmos as something to be desired, those who follow the Way of the Void seek this unity through annihilation. These nihilistic warriors channel the power of entropy, the gradual journey of all things in the universe towards nothingness. The followers of this Tradition use their power to accelerate this natural process of cosmic decay. Mortal or immortal, mundane or magical in origin, all will eventually become one in the inescapable void.

Entropic Touch

When you adopt this Tradition at 3rd level, you learn to draw upon the power of the void to destroy. As an action, you can touch a tiny, non-magical, object that is not being worn or carried and shunt it to an extradimensional space.

The object remains in this extradimensional space for as long as you can maintain your concentration on it, as if you were concentrating on a spell. If you maintain concentration for 1 hour, the object is permanently destroyed. If you break your concentration, the object reappears in an unoccupied space as close as possible to its previous location.

Once you use this feature to permanently destroy and object, you can't use it again until you finish a long rest, unless you expend 3 ki points to use this feature again.

The size of the non-magical objects you can destroy with this feature increases as you gain levels in this class: at 6th level (Medium), 11th level (Large), and 17th level (Huge).

Void Wielder

Starting at 3rd level, your connection to the nothingless void allows you to channel its power through your strikes. Once per turn, when you hit a creature with an unarmed strike or monk weapon attack, you can spend 1 ki point to deal an additional 1d12 necrotic damage to the target.

If you use this feature to deal necrotic damage to a creature that is concentrating on a spell, it has disadvantage on its Constitution saving throw to maintain its concentration.

Vorpal Step

Beginning at 6th level, when you use Step of the Wind, you draw upon the power of the void to discorporate. Until the end of your current turn, you can move through non-magical objects and creatures as if they were difficult terrain.

If you end this movement inside an object or creature, you are instantly shunted to the nearest unoccupied space, taking 1d10 force damage for every 5 feet you are forced to move.

Degraded Form

Your entropic touch can undo arcane magic. Starting at 11th level, you can use an action to touch a creature, object, or magical effect and spend 4 ki points to cast dispel magic at 3rd-level, using Wisdom as your spellcasting modifier.

Also, when you pass through a creature with Vorpal Step, you can force it to make a Constitution saving throw. On a failed save it takes force damage equal to your Martial Arts die + your Wisdom modifier. You can only force a creature to make this saving throw once per turn.

Avatar of Entropy

Beginning at 17th level, you can use your action to touch a creature and force it to make a Constitution saving throw. On a failed save, the creature suffers the effects of disintegrate as if it had been cast at 6th-level.

Once you use this ability you can't use it again until you finish a long rest, unless you spend 6 ki points to use it again.
