Ability to cast spells.
Benefit
When you select this feat, choose a creature type or a humanoid subtype from the
Ranger Favored Enemies table (Core Rulebook 64). When creatures of the chosen type attempt saving throws against your spells, they treat the spells' DCs as 1 higher. If you also have the favored enemy class feature and the chosen type is already a favored enemy of yours, such creatures treat your spells' DCs as 2 higher.
Special
You can take this feat multiple times. Each time you do, it applies to a different creature type.
