You inherit the spells at each indicated ranger level in the Planeswalker Spells table as ranger spells.
When a creature you can see within 120 feet of you attempts to teleport, you can take the Magic action as a reaction and expend one use of your Channel Nature feature to cause the creature to make a Wisdom saving throw. Any creature not originally from the current plane of existence automatically fails the saving throw. On a failed save, the teleportation fails.
When you mark a creature with your Hunter's Mark feature, all damage dealt by your attacks against that creature becomes force damage, and the creature takes an extra damage die of your Hunter's Mark feature at the end of each of its turns.
You can use your Primeval Awareness feature to detect the location of any planar portals, and where at and where to a creature has used any means of teleportation within a 24-hour period. When you use your Primeval Awareness feature this way, its range increases to 10 miles.
You can take the Magic (Spellcast) action to cast the etherealness spell, but the duration of the spell is the current turn.
Once you use this feature, you can't use it again until you finish a short rest, unless you expend one use of your Channel Nature feature.
When you take the Attack action on your turn, you gain a teleportation speed of 30 feet until the end of the turn.
When you take damage from an attack, you can take the Magic action as a reaction to become immaterial against the triggering attack.
You can take the Magic action to cast the plane shift spell, without providing a spell slot or spell components.
Once you use this feature, you can't use it again until you finish a long rest, unless you expend one use of your Channel Nature feature.
