Path of The Bonebreaker

You have spent much of your life fighting creatures with their skeletons on the outside. Whether these be undead hordes or horrific monsters with hard, chitinous shells, you are well experienced at breaking through these tough exteriors and exposing the soft weak spots underneath or shattering skeletons to dust.

The Path of the Bonebreaker excels at close range brawls, where they can deal blunt force trauma to cause maximum damage to hardened targets & shrug off retaliatory strikes.

Shoulder Charge

At 3rd level, you learn how to leverage your momentum to cause damage and put your foes on the back foot. When you move at least 10 feet on your turn you can deal Bludgeoning damage equal to 1d6 + your strength modifier to a creature within 5 feet of you at the end of your movement. You can deal this damage once per turn.

If the creature is one size larger than you or smaller and you then hit the creature with an attack, the creature must make a strength saving throw (DC equals to 8 your Strength modifier + your Proficiency bonus) or be knocked prone. 

The size of the Shoulder Charge damage die increases as you level up: To 1d8 when you reach 8th level, 1d10 when you reach 12th level, and 1d12 when you reach 16th level.

Breaker of Bones

Once you reach 3rd level, you have become adept at crushing skulls & breaking through otherwise tough bones & similar material. While you are raging, any attacks you make that use your strength modifier ignore resistance to bludgeoning damage.

While you are raging, any attacks you make that use your Strength modifier ignore resistance to bludgeoning damage.

Once you reach 8th level, you ignore immunity to bludgeoning damage. Any creature with immunity to bludgeoning damage that you attack instead has resistance to bludgeoning damage.

Concussive Momentum

At 3rd level, your fury lets you move with the force of an avalanche; ever forwards. On your turn while raging, when you hit a creature with a strength melee attack that deals bludgeoning damage, that creature can't make opportunity attacks against you for the rest of your turn.

Armour Breaker

At 6th level, you know just where to strike to crack through armour and bone, leaving a weak point ready to be exploited.

While raging, if you score a critical hit with a strength melee attack that deals piercing or bludgeoning damage, you expose a weak point in that creature's defence. The next time that creature is hit with a melee attack, the creature has vulnerability to all of that attacks damage.

In addition, if a creature within your melee range suffers a critical hit from a weapon attack you can use your reaction to make a melee attack against that creature. 

Concussive Defence

At 10th level, a life of breaking bones and armour in brutal melee combat has taught you how to block out the worst of the pain. You gain resistance to bludgeoning and piercing damage.

You have also learnt how to use pain to invigorate you under the right circumstances.

While raging, when you take bludgeoning or piercing damage you gain a number of temporary hit points equal to half the damage dealt (rounded up) before applying resistances.

Any temporary hit points gained in this manner are lost once your rage ends.

Relentless Momentum

Your fury is unbound, breaking all before you. When you reach 14th level, if you make a Shoulder Charge while raging you can use your bonus action to make an additional melee attack against the creature. If you do so, you have advantage on the attack roll.
