Boots Of Friendly Terrain

Each pair of these supple leather boots corresponds to a specific sort of environment as defined by the ranger's favored terrain class feature (jungle, plains, and so on). A ranger wearing the boots can treat the corresponding environment of the boots as one of his favored terrains, granting him a +2 bonus. If he already has that particular environment as one of his favored terrains, his bonus for that terrain increases by +2.
