Path of The Durendar Rider

The Path of the Durendar Riders utilizes mobility and mounted combat to capitalize on a barbarian's strengths.

Your clan or tribe have developed unmatched mounted skill as part of your culture or lifestyle, often developing a symbiotic relationship with your mount. Dedicated riders can form a bond with their mount, allowing the barbarian to move and act in unison with it. The Rider may perform dazzling tricks in the saddle, or ride standing up to dive headlong into combat from Lizard back. The mount of a barbarian who chooses this path can become as enraged as its owner, wading into combat with hoof or claw, or charging headlong into a sea of enemies, trampling them underfoot.

Animal Speciality

Starting when you choose this path at 3rd level, you become more adept at handling a mount in combat. You gain proficiency in Animal Handling if you don't possess this skill already, or gain Expertise in this skill if you do.

Mounted Companion

Starting at level 3, you are able to form an everlasting bond with a Riding Lizard. This beast acts as your mount for class features. The Mount obeys your commands to the best of its abilities. The mount loses its Multiattack. When mounted your beast acts with you on your initiative and you can command it with a bonus action when you are not mounted it performs the dodge action when it is given no commands. Your beast understand all the languages you know but can't speak.

Once during your move, you can mount your beast when it is within 5 feet of you, or dismount without any cost in movement. You cannot mount a creature if you are incapacitated. 

You gain an advantage to Acrobatics (Dexterity) or Athletics (Strength) checks while mounted. If an effect moves your mount against its will while you're on it, you gain an advantage to succeed on a DC 10 Dexterity saving throw to avoid falling off the mount. You cannot land prone if you fall off your mount.

If your mount is knocked prone, you can use your reaction to dismount it as it falls and land on your feet. Otherwise, you are dismounted in a space within 5 feet it but are knocked prone.

When you gain your Mounted Companion at 3rd level, its proficiency bonus matches yours at +2. As you gain levels and increase your proficiency bonus, remember that your companion’s proficiency bonus improves as well, and is applied to the following areas: Armor Class, skills, saving throws, attack bonus, and damage rolls.
