This replaces the spells class feature.
Spell Pool: The sphere druid 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 level + her Wisdom modifier (minimum: 1). This pool replenishes once per day after roughly 8 hours of rest.
Magic Talents: A sphere druid gains 1 magic talent every level.
Nature Bond: If a druid chooses to gain a domain as her nature bond, she gains its associated sphere and a bonus magic talent from that sphere at 5th, 9th, 13th, and 17th level, as the sphere cleric.
This modifies the nature bond class feature.
Wild Heart: The sphere druid gains the Alteration sphere or a talent from the Alteration sphere as a bonus sphere at 4th, 10th, and 16th level. When spending a spell point to allow a shapeshift on herself and only on herself to endure without concentration, the effect lasts for up to 10 minutes per caster level instead of 1 minute per caster level. At 20th level, the effect can be made permanent until dismissed.
This replaces the Wild shape class feature.
Recommended Casting Tradition: The classic feel of the druid can be recreated through taking the verbal casting, prepared caster, and animal shaman (Mind) drawbacks.
