This replaces the spells class feature.
Spell Pool: The sphere skald 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 Charisma modifier (minimum: 1). This pool replenishes once per day after roughly 8 hours of rest.
Magic Talents: A sphere skald gains 1 magic talent every time she gains a caster level. This does not stack with caster levels gained from other sources.
Sphere Kenning (Su): At 5th level, a sphere skald is learned in the magic of other casters, and can expand his magic in untested ways. By increasing the casting time by 1 step, the sphere skald can add any one magic talent to his list of talents known for the purposes of a single use of a sphere ability. The sphere skald can choose a new base sphere with this ability. The sphere skald can use this ability once per day at 5th level, twice per day at 11th level, and 3 times per day at 17th level.
This replaces spell kenning.
Recommended Casting Tradition: The classic feel of the skald can be recreated through taking the verbal casting and somatic casting drawbacks.
