Tips and tricks for using the Iron Knuckles

As a member of the Knuckles weapon class, the Iron Knuckles scale in power with the player’s Fortitude attribute and The Brawler perk. The attack speed of this weapon can also be increased by investing in the Lightning Hands perk.
Knuckle weapons specialize in dealing rapid damage up close and personal. Knuckles attack very quickly and can stack up damage against a single target with repeated attacks.
Iron Knuckles are designed to increase the survivability of face-to-face fighting with zombies by applying debilitating effects that keep the wielder out of trouble. After investing in The Brawler perk, headshots against zombies can begin to negate their ability to infect the player, stagger enemies, knock them to the ground, stun them, and even blow up their heads with a single punch.
The main disadvantage of fist weapons is their short range of attacks. Players must be right in front of a target for their punches to connect, which risks retaliatory attacks. Striking with a power attack as soon as an enemy is within range can help stagger them and open them up for follow-up attacks. Additionally, we recommend wearing heavy armor if you intend to use knuckles as your main weapon.

When choosing mods and perks to compliment your Iron Knuckles, we suggest choosing anything that will increase your attack speed, reduce stamina consumption, and improve the chances to proc status effects such as stagger and knockdown. The Weighted Head and Ergonomic Grip mods are two great choices for improving your weapon.
Final thoughts on the Iron Knuckles
It’s admittedly pretty scary to stand toe-to-toe with zombies and fight with your own reinforced fists, but the supreme satisfaction that comes with punching an enemy’s head clean off makes it all worth it in the end. Plus, the bouquet of status effects The Fun Pimps added in are pretty nice too.
