Path of the Intellectual

Most view Barbarians as dumb brutes, but some are simply scientist, researchers, engineers, sages, professors and the like who have grown strong in both body and mind due to the mental benefits of regular and regular workouts. These barbarians take the path of the Intellect and use their intelligence to improve their workouts and use their workouts to improve their studying and learning. Those that have taken this path are the most likely type of barbarians to just be regular people working in STEM or at the gym, and they often confound people who underestimate their strength or intelligence.

Level 3: Planned Workout

Your mind has helped you hone your own body. Whenever you make an Strength check or Strength saving throw, you can choose to add your Intelligence modifier to the roll. In addition, you have advantage on Intelligence saving throws. Whenever you use this ability, it represents using the right muscle groups and technique to achieve a feat of strength.

Level 6: Improved Primal Knowledge

You can make your list of Primal Knowledge skills as Strength checks even when your Rage is inactive. In addition, you add Animal Handling, Medicine and all Intelligence skills to your list of Primal Knowledge skills. When you use this ability, your Strength represents primal power coursing through you, honing your mind and agility, bearing, and senses.

Level 10: Mind and Body

You have gained such an understanding of humanoid anatomy along with how to use your muscles and force to achieve a desired outcome that you can use that against other humanoids. When you attack a humanoid creature, you can add both your strength and intelligence modifier to attack and damage rolls. In addition, you can choose to add you intelligence modifier to your AC instead of your dexterity modifier.

Level 14: Intellectual Discovery

You have studied your own Rage. Through in-the-field experimentations, you have found a method to maintain Concentration and cast spells while your Rage is active. In addition, you can use your Strength Modifier as your spellcasting ability instead of Intelligence, Wisdom or Charisma modifier while your Rage is active. You can choose to teach one or more barbarians you share a language with how to do this during a Short or Long Rest, and they can benefit from this ability until their next Long Rest.
