Path of Momentum

For most barbarians, their rage fuels their power, enabling them to unleash devastating blows. However, some barbarians channel their fury into a different mechanism: speed. These barbarians fight with blinding speed, almost akin to teleportation at times, and are almost impossible to catch.

Flash Step

Starting when you choose this path at 3rd level, you can channel your rage into bursts of incredible speed. While raging, you can teleport up to 30 ft. on your turn. You can use this feature a number of times equal to your proficiency modifier, and resets after a long rest.

Raging Speed

Beginning at 6th level, while raging, your speed is doubled, and moving out of the space of another creature doesn't provoke an attack of opportunity.

Sonic Blows

Beginning at 10th level, you can make attacks as fast as your movement. While raging, if you move within 5 ft. of a creature and do not end your turn within 5 ft. of that creature, or teleport within 5 ft. of a creature, you make take the Attack action against that creature without using your action. You may only use this feature once per turn.

Godspeed

Starting at 14th level, the range of your Flash Step is increased to 100 ft., your speed while raging is tripled (this does not stack with Raging Speed), and you can make an additional attack when taking the Attack action while raging. In addition, the power of your legs makes the ground crack and shatter. While raging, any terrain you move over becomes difficult terrain, and you become immune to the effects of difficult terrain.
