Path of the Spectral Warrior [Better]

The Spectral Warrior Barbarian is a Powerful and Resourceful Barbarian. 

Whether these spectral powers manifested from your ancestors, a rift in the Weave, or Just some magic weapons you found; will aid in battle as a protective or offensive force.  (Writers Note: This subclass is based off of Raphael from ROTTMNT, so there's the inspiration.)

Spectral Forms

Starting when you choose this path at 3rd level, you pick from one of the Spectral Forms Below. These last until your Rage Ends. At 6th Level you can activate 2 of these affects at once, and 3 at 10th level, and 4 at 14th level.

Power Punch Jutsu: While raging your reach for melee attacks increases by 5 ft.

Mystic Punch Jutsu: While raging you can attack as a bonus action with no penalties. 

Power Smash Jutsu: While raging your melee attacks deal extra damage equal to your Proficiency Bonus.

Mystic Giant Jutsu: While raging you gain a spectral armor that increases your size to large. 

Power Charge Jutsu: While raging you gain a plus 15 to your movement speed.

Mystic Grapple Jutsu: While raging you gain a +3 to all grapple checks.

Spectral Defense and Offense

At 6th Level, When you activate Rage, you gain temporary Hit Points equal to your barbarian level.  Your Weapon attacks can deal force damage instead of the base damage. You also become resistant to force damage.

Protective Capacity

Beginning at 10th level, you have the protective capacity to keep you and your allies safe from harm. When you activate this ability, you cast Leomund's Tiny Hut but only as a ritual. When you cast this spell, it looks as if a group of spectral guards are patrolling the perimeter.

Ultimate Hibernator Jutsu

Starting at 14th level, while raging you can expend a bonus action to make your next melee weapon attack deal extra force damage equal to your barbarian level.

The target must succeed a Strength Saving Throw or go Prone until your next turn. (The DC for this attack is 8 + your Proficiency Bonus + Your Strength Modifier) you can do this a number of times equal to your proficiency bonus per long rest.
