If you're looking for a melee build that turns pain into power, Bone Shatter Juggernaut is one of the most brutal, rewarding, and kinetic experiences you can have in Path of Exile 2. It thrives on stacking trauma—yes POE 2 Currency Orbs, literally hurting yourself—to unleash staggering damage output. With the Juggernaut's naturally tanky profile and new utility in POE2, this build strikes a satisfying balance between survivability and all-out carnage.
What Is Bone Shatter?
Bone Shatter is a melee slam skill that deals physical damage and applies Trauma to the player whenever it hits an enemy. Trauma increases your physical damage but stacks rapidly and deals physical damage to you over time. The skill excels when you can sustain the self-damage while scaling attack speed and trauma stacks.
Why Play Bone Shatter Juggernaut?
Pros:
    Extremely high DPS potential
    Scales naturally with self-inflicted trauma
    Juggernaut's mitigation makes it much safer than other classes
    Easy to gear for early on
    Satisfying, weighty melee gameplay
Cons:
    Self-damage must be managed carefully
    Requires investment into leech, regen, or armor scaling
    Some ranged enemies or DoTs can overwhelm if you're not careful
Core Mechanics
Trauma Stacking
Each hit with Bone Shatter applies a stack of Trauma to you. The more you hit, the more Trauma you build up, which increases your base damage significantly. However, Trauma causes recurring self-damage, so managing it is crucial.
The Juggernaut Advantage
Juggernaut's access to high armor, stun immunity, Unbreakable (regen per 10 strength), and Unflinching (Endurance Charges) make it ideal for tanking through the self-damage. You can also spec into:
    Endurance Charge generation
    Physical damage reduction
    Life regen and armor scaling
