Spell Pool: The sphere hunter gains a small reservoir of energy she can call on to create truly wondrous effects, called a spell pool. This pool contains a number of spell points equal to her class level + her Wisdom modifier. This pool replenishes once per day after roughly 8 hours of rest.
Magic Talents: A sphere hunter gains a magic talent every time she gains a caster level. This does not stack with caster levels gained from other sources.
Recommended Casting Tradition: The classic feel of the hunter can be recreated through taking the verbal casting and animal shaman (Mind) drawbacks.
