Note: This archetype is sometimes called the psychic medium.
Casting
A sphere medium may combine spheres and talents to create magical effects. A sphere medium is considered a Low-Caster. (Note: All casters gain 2 bonus talents and a casting tradition the first time they gain the casting class feature.)
This replaces the spells class feature.
Spell Pool
A sphere medium 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 casting ability modifier (minimum 1). This pool replenishes once per day after roughly 8 hours of rest.
Magic Talents
A sphere medium gains a magic talent at 2nd level and every even level thereafter.
Exclusive Spirit (Su)
A sphere medium loses access to both the archmage and the hierophant spirits. In their place the sphere medium gains access to the spherecaster spirit.
This alters the spirit class feature.
Spherecaster Spirit
Spirit Bonus
When you channel a spherecaster, your spirit bonus applies to your caster level.
Seance Boon
Gain a temporary spell point that lasts for 24 hours, or until you change spirits.
Favored Locations
Areas of unusual magic, hallowed/unhallowed areas, and libraries.
Influence Penalty
Take a penalty to concentration checks equal to twice your spirit bonus.
Taboos
Choose one: You must provide magical assistance whenever asked; you must use your own magical solution to a problem if you can, even if a mundane solution that would require fewer resources is available; you must decline magical aid from others at all times and you must attempt a Will saving throw against even harmless spells and abilities.
Sphere Apprentice (Lesser, Su): Grant yourself the benefit of any one magic talent you do not possess.
Sphere Surge (Intermediate, Su): You may allow the spherecaster spirit to gain 1 point of influence over you to reduce the spell point cost of a sphere talent or ability you use by 1.
Sphere Adept (Greater, Su): Grant yourself the benefit of any two magic talents you do not possess.
Sphere Master (Supreme, Su): Once per day, you may cast any sphere talent or ability you know without spending any spell points.
Trickster Alternate Base Ability
When channeling the trickster spirit, a medium may choose to benefit from the following ability in place of trickster’s edge.
Talented (Base, Su)
You gain two skill talents of your choice that you meet the prerequisites for, plus an additional skill talent at 6th, 11th, and 17th levels. You may choose different talents each time you channel a trickster spirit.
