  Primal Paths 
  Rage burns in every barbarian’s heart, a furnace that drives 
  him or her toward greatness. Different barbarians attribute 
  their rage to different sources, however. For some, it is an 
  internal reservoir where pain, grief, and anger are forged 
  into a fury hard as steel. Others see it as a spiritual blessing, 
  a gift of a totem animal. 
  Path of Iron 
  Of all the innovations man has made over the years, one 
  would be hard pressed to find a more significant invention 
  than steel. With the discovery of steel, man gained a nearly 
  unparalleled ability to carve his way into the world around 
  him, and through the beasts and enemies that held him at 
  bay from the darkest reaches of the world. To a barbarian 
  of the Iron, steel isn't just what he shapes into his weapons 
  and his armor, it lies in his very heart and soul. 
  Iron Frenzy 
  You excel at fighting in the heaviest armor and while using 
  the heaviest weapons, leaning to use their weight to your 
  advantage. At 3rd level, you gain proficiency in heavy 
  armor, and you may gain the benefits of Rage while 
  wearing heavy armor. Additionally, while raging, once per 
  turn you may deal an additional 1d4 damage with a melee 
  attack from a heavy melee weapon. 
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
  Juggernaut 
  You are an unstoppable force, and no creature can impede 
  you from your chosen path. Starting at 6th level, you may 
  benefit from your Fast Movement bonus speed while 
  wearing heavy armor, and you are considered 1 size 
  category larger for the purposes of shoving and moving 
  through a hostile creature's space. If you move at least 10 
  feet in a straight line before attempting to move through a 
  hostile creature's space, you do not treat that space as 
  difficult terrain, and you do not provoke an opportunity 
  attack from that creature. 
       Starting at 14th level, you are considered 2 size 
  categories larger. 
  Riddle of Steel 
  Crafting and metalworking are in your heart, your blood, 
  and your soul. At 10th level, you gain proficiency with 
  smith's tools, and while crafting armor or weapons, you 
  make progress at a rate of 50 gp per day. 
  Iron Giant 
  Though massive, your armor and weapons are but tools for 
  your greatness; it is you who is larger than life. Starting at 
  14th level, while wearing heavy armor and raging, you gain 
  the Enlarge effect of the enlarge/reduce spell, though it is 
  not a magical effect and cannot be dispelled. This effect 
  ends when your rage ends. 
  New Feat 
  Brutal Grip 
  You've learned to use the weight of your weapons 
  effectively, and have adapted to use large weapons one-
  handed. 
  • Increase your Strength score by 1, to a maximum of 20. 
  • When wielding a versatile weapon in one hand, you can 
  use the two-handed damage die. 
  • You may wield a two-handed melee weapon in one 
  hand, treating it as a one-handed weapon. You have 
  disadvantage on attack rolls made when wielding a two-
  weapon this way.
