Quick answer: Worldbreaker Fist forms from Fist Fragment: Core and Fist Fragment: Shell. Take both to the Iron Fist Master’s gravestone, about 39 m from the Burial Grounds bell, during Heart of the Fist.
Where to get Worldbreaker Fist
Worldbreaker Fist comes together at the Iron Fist Master’s gravestone in the Crimson Forest, about 39 m from the Burial Grounds bell, during the tale Heart of the Fist. It takes two fragments:
| Fragment | Where it comes from | Card text |
|---|---|---|
 Fist Fragment: Core | Reward from the Iron Fiend and Jade Dancer fight in Use It Against Them | “A fist fragment from the Iron Fiend’s gauntlets, still imbued with unwavering martial resolve. Those fists were raised only against formidable foes, to protect those worth protecting.” |
 Fist Fragment: Shell | The gravestone itself, after your first talk with the Iron Fiend | “A fist fragment from the Iron Fiend’s gauntlets, still imbued with unwavering martial resolve. Those fists were raised only against formidable foes, to protect those worth protecting.” |
With both fragments, interact with the gravestone again. It gives you the Worldbreaker Fist and finishes the tale.
Worldbreaker Fist item card
The item card reads:
Beneath the forbidding iron shell, what was once hollow is whole again.
The perseverance to hone one’s fists, the pursuit of greater heights in the martial arts, the resolve held within clenched hands, and the purpose behind every strike. Together, they form a fist powerful enough to shatter the world.
Its effect line reads: “Used to Soul Temper the Iron Gauntlets.”
What Worldbreaker Fist does
Worldbreaker Fist is used only to Soul Temper the Iron Gauntlets.
To apply it, visit Myst in the Order’s underground tavern in Pangzhen and Soul Temper the gauntlets. The process costs 5,000 Remnant Dust plus the Worldbreaker Fist.
The tempered Iron Gauntlets gain Fist Wave, which has the effect “Each Phantom Edges attack releases a Fist Wave forward.”
