Rasgax Howlers

In addition to their howls, Rasgax Howlers are known for their exceptional riding skills. Weather mounted on warhorses, go korols, or even giant vultures a mounted Rasgax Howler is a farce unto itself. 
        At 3rd level a barbarian gains the Primal Path feature. The following Rasgax Howler option is available to a barbarian, in addition to those normally offered.

Howl

Starting when you choose this path at 3rd level, you can emit ear-splitting howls capable of stopping your enemies in their tracks. While raging, any creature who targets you with a harmful spell that can hear you must first make a Wisdom saving throw against a DC equal to 8 + your proficiency + your Charisma modifier. Creatures immune against being frightened automatically succeed on their saving throw. On a failed the creature has disadvantage on its attack rolls against you until your rage ends. If the creature succeeds on its initial saving throw, it is immune to this trait until your rage ends. this effect doesn't protect you from area of effects, such as fireball.   

 

Saddleborn

You gain proficiency in Animal Handling. In addition, mounting and dismounting a creature costs you only 5 feet of moment, rather than half your speed.

Seasoned Explorer

At 6th level, while traveling for an hour or more outdoors, difficult terrain doesn't slow your groups travel and you can't become lost except by magical means.  

Rasgax Pack Lord

Beginning at 10th level, your howl protects your comrades from harm, as well. Any number of creatures of your choice within 10 feet of your Howl while you are raging.  

Dhadrok's Howl

At 14th level, while you are howling and a creature makes a melee weapon attack against you and misses, you can use your reaction to force that creature to make another Wisdom saving throw against your Howl DC. On a failed save, the creature takes psychic damage equal to half your Barbarian level and is frightened of you  until your rage ends, or it can no longer hear you.
