Knowledge (Planes)

(Passive) INT
  Possessed By: Some Humans, Grey Elves, Bards, Mages, Monks, Paladins, Rogues, Alienists, Blackguards, Earthsingers, Loremasters, Tattoo Mystics, Knowledge priests.
  Effects:  This skill gives a character knowledge of the many planes of existance, with the following specific benefits:
   * Planar Travel (Passive): This skill is necessary to cast plane-travelling spells like plane shift safely. When moving across a wilderness map on a different plane, the lower of a character's Knowledge (Planes) and Wilderness Lore is used for most things that Wilderness Lore alone usually achieves.
   * Outsiders (Passive): Knowledge (Planes) can also aid the character in fighting outsiders who are not also demons, devils or celestials (who are covered by their own skill). By using a thorogh knowledge of their behaviour, biology and weaknesses, this skill allows a character the following bonuses when fighting such outsiders: his effective DC is increased by [Skill Rating / 3] against their attacks, and his understanding of their banes and biology increases the threat ratings of his attacks against them by [Skill Rating / 9]. He can also summon them more effectively; general outsiders summoned by such a caster have a [Skill Rating x 5]% bonus to their hit points.
   * Identify Monsters (Passive): The Knowledge (Planes) skill can be used to identify outsiders (other than celestials, demons and devils), as described under Appraise.
