Path of the mental

Barbarians that choose the path of the mental are able to tap into some abilities that most barbarians can't. 

(My first homebrew subclass!)

Power of the mind

You can add your int bonus to attacks. Additionally while raging you are resistant to psychic dmg

Soul strike

When raging you can make your attack ranged int+ number of times(30ft) and magical. It does the same dmg and you can add melee only abilities on the hit but you can't take reactions if you use this ability

Shielded mind

You can choose to be immune to passive mind reading. Additionally while in rage you have advantage on INT saves

Metal muscles

All your attacks are magical and you have a 2d8+(int bonus) psychic dmg on all hits while in rage
