This replaces the spells class feature.
Spell Pool: The sphere inquisitor gains a small reservoir of energy he can call on to create truly wondrous effects, called a spell pool. This pool contains a number of spell points equal to his level + his Wisdom modifier (minimum: 1). This pool replenishes once per day after roughly 8 hours of rest.
Magic Talents: A sphere inquisitor gains 1 magic talent every time he gains a caster level. This does not stack with caster levels gained from other sources.
Recommended Casting Tradition: The classic feel of the inquisitor can be recreated through taking the Verbal Casting, Focus Casting, Aligned Combatant (Destruction), and Aligned Protection (Protection) drawbacks.
