Animal Focus (Su)
Replaces: Shield Ally
At 4th level, as a swift action a naturalist can enhance his eidolon with the aspect of an animal. Each time he uses this ability, he can select a hunter’s animal aspect (see page 27) and apply it to his eidolon. His hunter level for this ability is equal to his summoner level – 2. He does not gain the ability to apply an animal aspect to himself (see Shared Focus, below). This effect lasts until the eidolon is dismissed or sent back to its home plane.
When an animal aspect is applied to an eidolon, its form is altered by superficial physical changes appropriate to that aspect. For example, using aspect of the bat might give the eidolon larger ears and eyes and perhaps membranes of skin connecting its limbs to its body, while using aspect of the stag might give the eidolon antlers and hooflike nails on its feat. None of these changes interfere with any of the eidolon’s natural or magical abilities.
This ability replaces shield ally and greater shield ally. Second Animal Focus (Su): At 10th level, whenever a naturalist uses animal focus, he can apply two animal aspects to his eidolon. The eidolon’s form gains superficial physical changes appropriate to the chosen aspects. This ability replaces the aspect summoner class ability.
