Chaos Warden

You are a conduit for the magical forces of chaos and raw arcane power permeates your every cell. You channel your power through your body enhancing your physical form as well as your weapons. your raw magic may be inherited from a magical ancestor or perhaps you were exposed to a strong magical force and absorbed its power. 

Chaotic Vessel

At 1st level, your enhanced body allows you to effectively arm yourself for battle. You gain proficiency with light armor, medium armor, shields, and a simple or martial weapon of your choice that lacks the heavy property. Additionally whenever you make a melee weapon attack with a weapon you are proficient with that lacks the heavy property,  you can use your Charisma modifier, instead of Strength or Dexterity, for the attack and damage rolls

Arcane Supplement

When you reach 3rd level in this class, while you are conscious, whenever you make an ability check or are forced to make a saving throw using your strength or dexterity you may spend 2 sorcery points and add your charisma modifier to the roll.

Chaotic Smite

6th-level Chaos Warden feature

You can attack twice, instead of once, whenever you take the Attack action on your turn. Moreover, you can cast one of your cantrips in place of one of those attacks.

Additionally at 6th level, when you take the attack action, if you have not already cast a spell this turn, you can expend a spell slot and begin concentrating as if you were concentrating on a spell. The next time you hit a creature with a melee weapon attack using a weapon you are proficient with that lacks the heavy property while concentrating in this way, you unleash a burst of magical energy dealing additional damage. The extra damage is 2d8 for a 1st-level spell slot, plus 1d8 for each spell level higher than 1st. The damage increases by 1d8 if the target is a construct. You may choose the damage type of the Chaotic Smite, but you must know a spell or cantrip that always deals damage of that type when it deals damage. Your concentration ends after 1 minute if you have not hit a creature with Chaotic Smite

Choosing to concentrate on Chaotic Smite counts as casting a spell meaning that at most you can only cast a cantrip on the same turn that you use it.

Arcane Enhancement

At 14th level, your magic bolsters your body even further. Your AC increases by 2 and your walking speed increases by 10 feet while you are not wearing heavy armor.. 

Chaotic Form

Starting at 18th level, you can spend 6 sorcery points as a bonus action to overload your body with magic. In this form, you gan the following benefits:

You have resistance to bludgeoning, perching, and slashing damage

You  have advantage on strength, dexterity, and constitution ability checks and saving throws. 

When you take the attack action on your turn, you may spend 2 sorcery points to make a total of three attacks

Your Chaotic Smite does not require concentration

You remain in this form for 1 minute. It ends early if you are incapacitated, if you die, or if you dismiss it as a bonus action.
