OK, this is something I came up with the basics for in about five minutes, and have expanded somewhat since then. The main idea is an arcane casting class that is not limited in the number of spells per day they can cast. However, because of that, they only know a very small selection of spells they know.
BAB: As Wizard
Good saving throws: Will
Skill points per level: 4+int (x4 at first level)
Hit Die: d4
Weapon and armor proficiencies: Chi Wizards are proficient with all simple weapons but not with armor or shields.
Spellcasting: Chi Wizards cast arcane spells in the same way that a Sorcerer does. Like a wizard, he gains bonus spells and the difficulty of his spells is based off his Intelligence modifier. A Chi Wizard begins play knowing 4 0-level spells, plus one additional 0-level spell for each point of his Intelligence bonus. A Chi Wizard learns one new spell of any level he can cast spells from every level.
However, unlike the Wizard, Sorcerer, or any of the other Arcane casting classes, a Chi Wizard draws his arcane energy directly from the surrounding environment. Because of this, he gains new spell levels much slower than most classes. Most classes can cast spells of a spell level equal to 1/2 their caster level, plus or minus one. The Chi Wizard can only learn and cast spells of a spell level equal to 1/3 their Chi Wizard level. This means that they do not gain the ability to learn first level spells until Chi Wizard level 3, second level spells at level 6, and so forth.
Selective Schooling: At first level, a Chi Wizard selects three schools of magic eligible for a Wizard to specialize in. These three schools are the only schools of magic that the Chi Wizard can learn spells from. For example, a Chi Wizard who selected Abjuration, Evocation and Conjuration would never be able to cast spells from the schools of Divination, Necromancy or Illusion, even from scrolls or magic-trigger items.
Channeled Casting: Beginning at first level, a Chi Wizard can increase the effectiveness of a spell by taking more time casting it. For every additional increment of time he spends casting a spell beyond the spells normal casting time, he increases his effective caster level by 1. For instance, a Chi Wizard casts a spell which has a casting time of a full-round action. If he instead spends 3 full rounds casting it, his effective caster level is increased by 2.
