This replaces the spells class feature.
Spell Pool: The sphere oracle 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 Charisma modifier (minimum: 1). This pool replenishes once per day after roughly 8 hours of rest.
Magic Talents: A sphere oracle gains 1 magic talent every level.
Oracle’s Strength (Su): A sphere oracle gains +1 spell point at 2nd level and every 2 levels thereafter. This replaces mystery spells.
Oracle’s Curse: If the sphere oracle selects a curse that normally grants bonus spells (for example, Haunted), he does not gain spells. Instead, he gains a bonus magic talent at 1st, 5th, 10th, and 15th levels, chosen from the sphere associated with that curse (for example, Haunted would grant magic talents from the Telekinesis sphere).
Recommended Casting Tradition: The classic feel of the oracle can be recreated through taking the Verbal Casting drawback.
