Path of the Siege

While most barbarians are skilled at breaking things in their rage, some have dedicated their inner fury for the sole purpose of destruction. These barbarians are more than just violent berserkers. They often intentionally place themselves at the heads of rebellions, penetrating a tyrant's walls so that a militia may charge in, and smashing bridges to stop pursuers from catching the innocent.

Destructive

Starting when you choose this path at 3rd level, you dedicate your rage for the purpose of destruction, and your ability to endure long sieges is enhanced. Your melee weapon attacks deal double damage to objects and structures. Additionally, you can add your proficiency bonus to any Constitution check you make that doesn't already use your proficiency bonus.

Sundering Strikes

Also at 3rd level, you have learned to direct all of your rage towards any object in your path, no matter who tries to stop you. While raging, when you use the Attack action on your turn, you can target an object that you can see that is being worn or carried. Add the Dexterity modifier of the creature holding or wearing the object to the object's AC. If the object does not have a damage threshold, its damage threshold is equal to its current Hit Points while it is being worn or carried.

Master of Arms

Beginning at 6th level, you have mastered the ability to use all weapons as tools of destruction. You have proficiency with improvised weapons. Additionally, when you make a melee weapon attack that deals a type of damage from the following list, you can change that damage type to one of the other listed types: bludgeoning, piercing, slashing.

Rending Blows

At 10th level, the overwhelming force of your destructive strikes momentarily cripples your opponents. During your rage, each creature, other than you, that is in physical contact with an object when you break it is paralyzed until the start of its next turn.

Once a creature is paralyzed in this way, you can't use this feature on that creature again for 24 hours.

Disastrous Force

Beginning at 14th level, when you're raging your destructive abilities surpass that of a natural disaster, and even your weakest blows have the potential to break an object apart. When you enter your rage, if you take the Attack action, any hit you score against an object or structure is a critical hit until the end of your turn.

Additionally, when you make a melee attack roll with a weapon, the target takes damage equal to your Strength modifier (minimum of 0) if the attack misses.
