Some rangers study their favored enemies and learn their ways, applying this knowledge to their own abilities and using their foes’ strengths against them. Infiltrators are willing to walk a mile in an enemy’s shoes so as to learn everything there is to know about their foes in order to more effectively hunt and kill them.
At 3rd level, an infiltrator learns how to copy the unusual abilities of his prey. He chooses one type of creature he has selected as a favored enemy, such as “aberrations.” The Ranger selects one ability or feat from the adaptation list for that type (see below). A Ranger can use adaptations for 10 minutes per day per Ranger level he possesses. This duration does not need to be consecutive, but it must be used in 10-minute increments. If the adaptation requires the Ranger to make a more specific choice (such as what skill to use with Skill Focus), this choice is permanent and cannot be changed.
At 8th, 13th, and 15th-level, the Ranger chooses another one of his favored enemy types and selects one adaptation from that type’s list, as well as an additional adaptation from any one list of a creature type he’s selected (including the one just chosen, if so desired). The infiltrator can only use one adaptation at a time. The ranger can use the camouflage and hide in plain sight class features whenever he is using adaptations.
Humanoid (halfling): fearless, halfling luck, keen senses, sure-footed, weapon familiarity.
This class ability replaces favored terrain.
How does a ranger with the Infiltrator archetype, which causes him to lose his favored terrain class feature, use his camouflage and hide in plain sight class features?
A ranger with the Infiltrator archetype can use the camouflage and hide in plain sight class features whenever he is using his adaptation class feature, regardless of the terrain he is in.
Official Update: In the Infiltrator archetype, in the adaptation class feature, add the following sentence to the end of the second paragraph:
“The ranger can use the camouflage and hide in plain sight class features whenever he is using adaptations.”
Editor’s Note: The updated wording has been applied.
