Slithering Retreat

Starting when you choose this path at 3rd level, you can quickly advance and retreat using slithering and winding movements. While raging, you may take the disengage action as a bonus action on your subsequent turns.

Inescapable

While raging, you may mark a creature when you hit them with an attack (no action required). This creature becomes the object of your frenzy, you have advantage on survival checks to track them and you know the direction to the target if it is within a mile of you. Additionally, you deal an additional 1d4 psychic damage to the target and you have disadvantage on attack rolls against other creatures.

You can release this mark by using an action, it can also be destroyed if the target is subject to a dispel magic (spell level equal to half your barbarian level).

The psychic damage you deal against your marked target increases as you gain levels in this class: 1d6 (5th), 1d8 (11th), 1d10 (17th).
