Path of the Haste

Haste barbarians are known for their remarkable speed and powerful strikes. They usually sleep a lot and are often lazy when not enraged. Their rage makes them more agile, running around a lot before ending their spike of energy.

Dashing Rage

Starting when you choose this path at 3rd level, you gain a movement peak when you rage. Whenever you rage, during the first round after you rage, you gain the bennefits of a dash action. During your rage, you can take a bonus action on each of your turns to take a Dash action. During your rage, if you move at least 20ft on a straight line towards a creature, your first attack deal extra damage equal to a fifth of the distance you ran.

Bulldozer Stride

Beginning at 6th level, while raging, you can pass through enemies with such high speed they cannot attack you. Whenever you rage, and take a dash action, you can move through spaces occupied by creatures. If you move at least 15ft on a straight line, every large or smaller creature within your movement line is pushed 5ft away and knocked prone.

Also, you do not provoke opportunity attacks while raging.

Opportunity Rage

Beginning at 10th level, you can use your rage to stop a passing target. Whenever a creaure moves within 5ft of you, you can use your reaction to enter in rage and immediatly attempt an opportunity attack, reducing its movement to 0 on a hit. The reduction lasts until the beggining of the creature's next turn.

Hasting Fury

Starting at 14th level, every time you rage, you can choose to gain an extra action on all your following turns until the rage ends. For each 2 times you chose to do so, you'll gain one level of exhaustion after the rage ends.
