The Juggernaut

Unstoppable, relentless, inexorable. A juggernaut is a creature that sets its mind on something, and then never stops until it reaches it. The juggernaut uses the momentum it build when it starts moving to further its ability to reach its destination without hindrances.

Momentum

Starting when you choose this path at 3rd level you learn to harness kinetic energy through Momentum Charges. While raging you may begin to accumulate charges that last until the start of your next turn; you gain one charge for every 10 feet you willingly move in a straight line, up to a maximum of charges equal to your Barbarian level. These charges may be spent in one of the following manners and only one option can be used per turn:

Deal additional damage on a melee attack; the bonus equals to the number of charges spent.

When you shove a target, you may spend charges to increase the distance you push it. The creature is knocked 5 feet away from you per charge spent up to a maximum of 50 feet.

You may spend 3 charges to cast Longstrider on yourself.

Not Even a Flinch

Also at 3rd level you become harder to hit while on the move. Attacks of Opportunity are made with disadvantage against you if you generated at least one Momentum Charge during the previous or current turn.

Unstoppable

Beginning at 6th level, you are always under the effect of a Freedom of Movement as long as you have at least one Momentum charge.

Stampede

Starting at 10th level you add the following options to your Momentum list:

You may spend 5 charges to cast Expeditious Retreat on yourself; you don’t need to concentrate on it, and it affects you until your rage ends. While under the effects of this spell, you cannot benefit from having cast Longstrider on yourself.

You may, as part of your attack action, spend 4 charges to cast Earth Tremor. You may further spend charges to cast it at higher level, with a cost of 2 charge per spell level up to a maximum of 10 charges (5th level spell slot equivalent). The DC for this spell equals: 8 + Prof. + Str mod.

Also at 10th level Attacks of Opportunity are now always made with disadvantage against you, regardless of possible conditions giving advantage to the attacker.

You may now also shove creatures up to two size categories larger than you.

Inexorable Pursuit

At level 14th you become the ultimate juggernaut and nothing can stand on your path. As a bonus action you can designate a creature within your line of sight as your target. This effect lasts for ten minutes and cannot be prevented or removed in any manner (unless your rage ends or you fall unconscious). While a target is marked you must always attempt move closer to it; moving towards it causes your speed to double, you generate twice the amount of charges (although the limit is still your Barbarian level) and you may use Momentum charges twice per turn.

As part of your movement you can shove aside any creature (up to two size categories larger than you) aside, possibly preventing an attack of opportunity.

You also deal double damageto all structures between you and the target.

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