Favored Terrain Feat 2Ranger Source Player Core pg. 158 Spring 2026, 1st PrintingArchetypes Nidalese Horselord*,
Steel Falcon*
* This archetype offers Favored Terrain at a different level than displayed here.
You have studied a specific terrain to overcome its challenges. Choose aquatic, arctic, desert, forest, mountain, plains, sky, swamp, or underground as your favored terrain. When in that terrain, you can ignore the effects of non-magical difficult terrain. If you have the unimpeded journey class feature, you gain a second benefit while in your favored terrain, depending on your choice:
- Aquatic You gain a swim Speed equal to your Speed. If you already had a swim Speed, you instead gain a +10-foot status bonus to your swim Speed.
- Arctic You need to eat and drink only one-tenth as much as usual, you aren’t affected by severe or extreme cold, and you can walk across ice and snow at full Speed without needing to Balance.
- Desert You need to eat and drink only one-tenth as much as usual, you aren’t affected by severe or extreme heat, and you can walk along sand at full Speed without needing to Balance.
- Forest, Mountain, or Underground You gain a climb Speed equal to your Speed. If you already had a climb Speed, you instead gain a +10-foot status bonus to your climb Speed.
- Plains You gain a +10-foot status bonus to your land Speed.
- Sky You gain a +10-foot status bonus to your fly Speed, if you have one.
- Swamp You can move across bogs at full Speed, even if they are deep enough to be greater difficult terrain or to normally require you to Swim.
