Molten Knight

Molten Knight | Fighter subclass

 You require at least 13 constitution in order to multiclass

Knights who committed grievous crimes are set into this armor that cannot be removed and it heats to set the man on fire until they pay for their heinous acts. Through this method, they adapted their bodies by speeding the flow from their blood vessels so much that they can sustain their fiery heat that now they can even sustain lava for several seconds. Through such torture, they found redemption and forgiveness, and whenever they see fire, they will always remember their past mistakes.
