Favored Enemy Spellcasting

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.
