Juggernaut

The path to becoming a juggernaut is one that almost all fighters know, involving immense dedication and sacrifice, pushing your endurance past its limits and breaking points, and having the mental fortitude to not completely shatter under the pressure. While others pursue feats of remarkable athleticism or cunning, your fighting spirit leads you to train in feats of stamina.

There are some with more raw strength, but that is not the concern of the juggernaut: they are like a mighty river wearing down a boulder, and less like an axe splitting a thick log in one blow. Juggernauts have always existed on the front lines of battle, absorbing punishment and battering back enemies to keep their allies safe; they are the lone champions told of in song who held back legions, refusing to die until the victory was won.

While they still have varying personalities, there is a trait common to juggernauts: peace. It's a quietness that comes from facing mortality unmasked. Juggernauts are willing- and in some cases eager- to live and die by the blade.

Immovable Object

When you're hit by an attack, you can use a Reaction to expend one Extra Attack for your following turn to reduce any damage you take by 3d4+your Constitution modifier. You can only use this feature a number of times equal to the number of extra attacks you can make before you take a long or short rest.

Unstoppable Force

It's hard to slow you down- due to your intense and grueling training, you've learned to ignore most setbacks that would impede your movement. You ignore any penalty to your speed from armor, and from non-magical difficult terrain.

 

Rock Solid

Your resilience has grown by leaps and bounds over your career. You receive 1 additional hit point per level, and your hit die per level become 3d4(or 7 if fixed).

Mountainous Stamina

Your durability and iron will allow you to endure almost unimaginable trials. You're immune to the Exhausted condition and only need 4 hours of rest to gain the benefits of a long rest. You also have advantage on death saving throws.

Undying Warrior

At this point in your career, you've become exceptionally difficult to kill. You do not become unconscious when at 0 or fewer HP, though taking damage then does force you to make a death saving throw. You also can use Indomitable to reroll death saving throws.
