I'm not sure if it needs spells or maneuvers or anything special like that, but I just had this thought and I had to act on it. Let me know what you think.

Skill Points at 1st Level:
(6 + Int modifier) × 4
Skill Points at Each Additional Level:
6 + Int modifier
Grace of the Fey (Ex):
Rangers get a +4 divine bonus to saving throws against Animals, Magical Beasts, Fey, or Giants. Further, they may communicate with such creatures, even if they have little intelligence, or do not share a language as if using Diplomacy. To do so the Ranger rolls 1d20 and adds a bonus equal to the number of Favored Terrains he has, or his Charisma modifier, whichever is higher. The starting attitudes of domestic animals are generally friendly, while wild animals usually start at unfriendly, and magical beasts, fey, and giants are assigned attitudes by the GM on a case by case basis. To use this ability the Ranger and the target creature must be able to clearly see each other and be within 30ft/favored terrain.
Favored Terrain (Ex):
At first level, second level, and every even level thereafter choose one of the following terrains: Any*, Aquatic, Desert, Forest, Hills, Marsh, Mountains, Plains, Underground, or Urban**. Against creatures with the chosen terrain listed under their Environment entry, while you are actually in said terrain, you gain a +1 bonus to AC and saving throws. Starting at 2nd level, while you are actually in said terrain, you deal those creatures 1d6 additional damage and overcome their critical immunity or fortification properties. At 4th level and every four levels thereafter your bonus to AC and saving throws increases by 1. Every four levels after 2nd your bonus to damage increases by 1d6. The extra damage granted by this feature is not precision damage and therefore damages creatures that would normally be immune to sneak attack or critical hits. Finally, for each Favored Terrain you possess choose any skill you have at least 1 rank in. You may take 10 with the chosen skill at any time while you are in your chosen environment even if you would be threatened or distracted.
Starting at 12th level you may choose any specific Plane as one of your Favored Terrains, such as the Seven Mounting Heavens of Celestia, the Infinite Layers of the Abyss, or the Elemental Plane of Fire, just to name a few.
*If you choose Any as one of your favored terrains you only get the bonuses from this ability against creatures with the Environment entry of Any, and you MAY NOT choose a skill when taking this Favored Terrain, nor can you take a 10 with any skills chosen through other terrains in just any terrain.
**If you choose Urban as one of your favored terrains you get the bonus against any creature that dwells in a permanent settlement of at least 400 creatures. You may choose a skill when you choose the Urban terrain.
Starting at 3rd level you gain the Scent quality (MM 314).
Starting at 5th level, while in any of your Favored Terrains you may use the Hide skill even if the terrain doesn't offer any cover or concealment.
Guiding Beacon (Ex):
Starting at 7th level, allies within 30ft of you gain the AC bonus you derive from your Favored Terrains. At 13th level they gain the bonus to saves. At 19th level they share your Flawless and Free Stride features.
Flawless Stride (Ex):
Starting at 9th level you ignore all negative effects of difficult terrain, including damage, and even if the terrain has been magically altered.
Starting at 11th level you gain the Tremorsense quality out to 60ft (MM 316).
Hide in Plain Sight (Ex):
Starting at 15th level, while in any of your Favored Terrains you may use the Hide skill even while being observed.
Free Stride (Ex):
Starting at 17th level, during your turns only, you benefit from a constant Freedom of Movement
effect as the spell.
