Extra Slot
Type of Feat: General
Prerequisite: Caster level 4.
Specifics: You gain one extra spell slot in your daily allotment, at any level up to one lower than the highest level of spell you can currently cast. For example, a 4th level sorcerer (maximum spell level 2nd) gains either an extra 0 level or 1st level slot, and is able to cast any spell he knows of the chosen level one more time each day. Likewise, a 4th level wizard can prepare any extra 0 level or 1st level spell he knows. Once selected, the extra spell slot never changes level. You can gain this feat multiple times. Each time, you gain an extra spell slot at any level up to one lower than the highest level of spell you can currently cast.
Use: Automatic.
Greater Spell Focus
Type of Feat: General
Prerequisite: Spell Focus.
Specifics: A character becomes even more adept with spells of a particular school of magic. The character gains a +2 bonus to the spell save DC for all spells of the chosen school.
Use: Automatic. This feat may be selected multiple times, but the effects do not stack. It applies to a different school of magic in each case.
Greater Spell Penetration
Type of Feat: General
Prerequisite: Spell Penetration.
Specifics: The character gains a +4 bonus on caster level checks to beat a creature's spell resistance.
Use: Automatic.
Practiced Spellcaster
Type of Feat: General
Prerequisite: Spellcraft 4 ranks.
Specifics: Your caster level for the chosen spellcasting class increases by +4. This can't increase your caster level beyond your HD. However, even if you can't benefit from the full bonus immediately, if you later gain noncaster-level HD you may be able to apply the rest of the bonus. For example, a human 5th-level cleric/3rd-level fighter who selects this feat would increase his cleric caster level from 5th to 8th (since he has 8 HD). If he later gained a fighter level, he would gain the remainder of the bonus and his cleric caster level would become 9th (since he now has 9 HD). A character with two or more spellcasting classes (such as a bard/sorcerer or a ranger/druid) must choose which class gains the feat's effect. This does not affect your spells per day or spells known. It only increases your caster level, which would help you penetrate SR and increase the duration and other effects of your spells. You may select this feat multiple times. Each time you choose it, you must apply it to a different spellcasting class. For instance, a 4th-level cleric/5th-level wizard who had selected this feat twice would cast cleric spells as an 8th-level caster and wizard spells as a 9th-level caster.
Use: Automatic.
