A perk with three ranks, with each granting a flat five point increase to Unarmed Damage.
The perk was expanded to five ranks, with each rank granting 20% increased damage, as opposed to the flat increase in the previous game. Higher ranks also grant improved benefits, such as a chance to disarm an enemy or cripple their limbs.
For Fallout 76, the perk was reduced to three ranks once more, with the damage bonus being drastically decreased. A single rank of this perk was also planned for the game's now defunct Nuclear Winter battle royale mode, but was never actually implemented.
Fallout: The Roleplaying Game
The perk has two ranks, it allows for increased unarmed damage by means of rolling another die.
Behind the scenes
The perk is a reference to the fictional Marvel Comics character Iron Fist, who channels his chi in order to unleash powerful unarmed attacks.
