Path of the Planar Warrior
The Path of the Planar Warrior is a dangerous journey that takes a barbarian to the far reaches of the multiverse and into contact with strange, unknown beings. Planar warriors learn to to give themselves an edge in battle by tapping into magical, extraplanar energy. Through their rage, they are able to not only increase their martial prowess, but manipulate space itself.
Primal Warp
Starting when you choose this path at 3rd level, you can shift through the fabric of space from one location to another, taking your enemies by surprise. If you are raging, you can use a bonus action to teleport to a point you can see within 25 feet of you immediately before or after you take the Attack action on your turn.
Spatial Escape
At 6th level, you gain the ability to quickly teleport yourself out of harm's way. If you are subjected to an effect that forces you to make a Dexterity saving throw to take only half damage, on a success, you can use your Primal Warp feature as a reaction. If this movement places you outside the area of effect, you take no damage. You can use this ability a number of times equal to your Rage damage bonus, and regain all expended uses when you finish a long rest.
Extradimensional Locker
Starting at 10th level, you have a personal extradimensional space you can access whenever you need. The space is two feet wide and six feet tall, and has a maximum capacity of 200 pounds. You can use a bonus action to summon any object in the locker into your hand, or to teleport any object you are holding into the locker.
Improved Warp
Beginning at 14th level, when you use the attack action to grapple or shove a creature after using your Primal Warp feature, you have advantage on Strength (Athletics) checks to do so. If you successfully grapple a creature in this way, you can use your Primal Warp feature (no action required) to teleport both you and the grappled creature. Additionally, you can use your Primal Warp feature to teleport a willing creature you are touching to a point you choose within 25 feet of you.
