Martial Archetype: Plane Walker
Bonus Proficiencies
When you choose this archetype at 3rd level, you gain proficiency in the Arcana skill. If you are already proficient in the skill, you add double your proficiency bonus to checks you make with it.
Blink
Starting when you take this archetype, you gain the ability to harness planar magic allowing you to travel in the blink of an eye. You gain a teleport speed equal to ten times your proficiency bonus. If you take the dash action on your turn, you can instead choose to use your teleport speed rather than your movement speed. Furthermore, you can only teleport to places within sight.
Plane Walk
Beginning at 7th level, you learn to step through the Planes. As a bonus action on your turn, you can cast the Etherealness or Plane Shift spells, only targeting yourself and ignoring material components. You can cast either of these spells in this way a number of times equal to half your proficiency bonus.
Planar Infusion
Additionally, at 7th level you can infuse the power of the different planes into your strikes. Your attacks count as magical for the purpose of overcoming resistance and immunity to nonmagical attacks and damage.
Hostile Blink
Starting at 10th level, whenever you use the Attack action, you can teleport up to 10 feet before each attack to an unoccupied space you can see.
Advanced Plane Walker
Beginning at 15th level, you have adapted to the different planes. At the end of a long rest you can choose to gain one resistance to any damage type and your attacks deal an additional damage die of your weapon of the same type. Furthermore, you can discern from which plane a creature is from if you spend at least one minute studying it.
Plane Rider
At 18th level, you become a master Plane Walker: a Plane Rider. As a Plane Rider you have unlimited use of your Plane Walk feature and can target an additional amount of creatures equal to your proficiency bonus.
