Hardening (5e Class)

From D&D Wiki

Jump to: navigation, search


Some individuals are born with quirk, extraordinary abilities that give to their users unique powers. One such quirk is Hardening that gives to those born with it the ability to enhance the durability and endurance of their bodies, protecting them from physical attacks. Hardening users can survive situations that would kill most creatures, without a single wound, causing swords strikes to be deflected and arrows to break on the impact with their skin.

Hardened Strength[edit]

Although it may appear that Hardening is a solely defensive power, this couldn't be further from the truth. By hardening their body, users are able to sustain heavy weights, which greatly increase their physical strength. They also can use their hardened limbs into lethal weapons, cutting with hardened knife hand strikes, or breaking bones, rock and steel with hardened fists.

Before you go Plus Ultra...[edit]

There are a few requirements before you can get your Hardening Quirk. You must meet the following requirements:

-Have a minimum Constitution and Strength of 14

-Can not be a Construct, Undead, or Elemental.

The Manliest User of the Hardening Quirk: Eijiro Kirishima
