Horizon Walkers guard the world against threats that originate from other planes or that seek to ravage the mortal realm with otherworldly magic. They seek out planar portals and keep watch over them, venturing to the Inner Planes and the Outer Planes as needed to pursue their foes. These rangers are also friends to any forces in the multiverseāespecially benevolent dragons, fey, and elementalsāthat work to preserve life and the order of the planes.
Horizon Walker Magic
Starting at 3rd level, you learn an additional spell when you reach certain levels in this class, as shown in the Horizon Walker Spells table. The spell counts as a ranger spell for you, but it doesn't count against the number of ranger spells you know.
Horizon Walker Spells
| Ranger Level | Spells |
|---|---|
| 3rd | protection from evil and good |
| 5th | misty step |
| 9th | haste |
| 13th | banishment |
| 17th | teleportation circle |
Detect Portal
At 3rd level, you gain the ability to magically sense the presence of a planar portal. As an action, you detect the distance and direction to the closest planar portal within 1 mile of you.
Once you use this feature, you can't use it again until you finish a short or long rest.
See the "Planar Travel" section in chapter 2 of the Dungeon Master's Guide for examples of planar portals.
Planar Warrior
At 3rd level, you learn to draw on the energy of the multiverse to augment your attacks.
As a bonus action, choose one creature you can see within 30 feet of you. The next time you hit that creature on this turn with a weapon attack, all damage dealt by the attack becomes force damage, and the creature takes an extra 1d8 force damage from the attack. When you reach 11th level in this class, the extra damage increases to 2d8.
