These Special Abilities are derived from SRD 3.5 Metamagic Feats.
As a spellcaster’s knowledge of magic grows, she can learn to cast spells in ways slightly different from the ways in which the spells were originally designed or learned. Preparing and casting a spell in such a way is harder than normal but, thanks to metamagic feats, at least it is possible. Spells modified by a metamagic feat use a spell slot higher than normal. This does not change the level of the spell, so the DC for saving throws against it does not go up.
Wizards and Divine Spellcasters: Wizards and divine spellcasters must prepare their spells in advance. During preparation, the character chooses which spells to prepare with metamagic feats (and thus which ones take up higher-level spell slots than normal).
Bards choose spells as they cast them. They can choose when they cast their spells whether to apply their metamagic feats to improve them. Such a character must also take more time to cast a metamagic spell (one enhanced by a metamagic feat) than he does to cast a regular spell. If the spell’s normal casting time is 1 action, casting a metamagic version is a full-round action. For a spell with a longer casting time, it takes an extra full-round action to cast the spell.
Spontaneous Casting and Metamagic Feats: A cleric spontaneously casting a cure or inflict spell can cast a metamagic version of it instead. Extra time is also required in this case. Casting a 1-action metamagic spell spontaneously is a full-round action, and a spell with a longer casting time takes an extra full-round action to cast.
Effects of Metamagic Feats on a Spell: In all ways, a metamagic spell operates at its original spell level, even though it is prepared and cast as a higher-level spell. Saving throw modifications are not changed unless stated otherwise in the feat description.
The modifications made by these feats only apply to spells cast directly by the feat user. A spellcaster can’t use a metamagic feat to alter a spell being cast from a wand, scroll, or other device.
Metamagic feats that eliminate components of a spell don’t eliminate the attack of opportunity provoked by casting a spell while threatened. However, casting a spell modified by Quicken Spell does not provoke an attack of opportunity.
Metamagic feats cannot be used with all spells. See the specific feat descriptions for the spells that a particular feat can’t modify.
Multiple Metamagic Feats on a Spell: A spellcaster can apply multiple metamagic feats to a single spell. Changes to its level are cumulative. You can’t apply the same metamagic feat more than once to a single spell.
Magic Items and Metamagic Spells: With the right item creation feat, you can store a metamagic version of a spell in a scroll, potion, or wand. Level limits for potions and wands apply to the spell’s higher spell level (after the application of the metamagic feat). A character doesn’t need the metamagic feat to activate an item storing a metamagic version of a spell.
Counterspelling Metamagic Spells: Whether or not a spell has been enhanced by a metamagic feat does not affect its vulnerability to counterspelling or its ability to counterspell another spell.
FEAT DESCRIPTIONS
Here is the format for feat descriptions.
FEAT NAME [TYPE OF FEAT]
Prerequisite: A minimum ability score, another feat or feats, a minimum base attack bonus, a minimum number of ranks in one or more skills, or a class level that a character must have in order to acquire this feat. This entry is absent if a feat has no prerequisite. A feat may have more than one prerequisite.
Benefit: What the feat enables the character (“you” in the feat description) to do. If a character has the same feat more than once, its benefits do not stack unless indicated otherwise in the description.
In general, having a feat twice is the same as having it once.
Normal: What a character who does not have this feat is limited to or restricted from doing. If not having the feat causes no particular drawback, this entry is absent.
Special: Additional facts about the feat that may be helpful when you decide whether to acquire the feat.
AUGMENT SUMMONING [GENERAL]
Prerequisite: Spell Focus (conjuration).
Benefit: Each creature you conjure with any summon spell gains a +4 enhancement bonus to Strength and Constitution for the duration of the spell that summoned it.
BREW POTION [ITEM CREATION]
Prerequisite: Caster level 3rd.
Benefit: You can create a potion of any 3rd-level or lower spell that you know and that targets one or more creatures. Brewing a potion takes one day. When you create a potion, you set the caster level, which must be sufficient to cast the spell in question and no higher than your own level. The base price of a potion is its spell level x its caster level x 50 gp. To brew a potion, you must spend 1/25 of this base price in XP and use up raw materials costing one half this base price.
When you create a potion, you make any choices that you would normally make when casting the spell. Whoever drinks the potion is the target of the spell.
Any potion that stores a spell with a costly material component or an XP cost also carries a commensurate cost. In addition to the costs derived from the base price, you must expend the material component or pay the XP when creating the potion.
COMBAT CASTING [GENERAL]
Benefit: You get a +4 bonus on Concentration checks made to cast a spell or use a spell-like ability while on the defensive or while you are grappling or pinned.
EMPOWER SPELL [METAMAGIC]
Benefit: All variable, numeric effects of an empowered spell are increased by one-half.
Saving throws and opposed rolls are not affected, nor are spells without random variables. An empowered spell uses up a spell slot two levels higher than the spell’s actual level.
ENLARGE SPELL [METAMAGIC]
Benefit: You can alter a spell with a range of close, medium, or long to increase its range by 100%. An enlarged spell with a range of close now has a range of 50 ft. + 5 ft./level, while medium-range spells have a range of 200 ft. + 20 ft./level and long-range spells have a range of 800 ft. + 80 ft./level. An enlarged spell uses up a spell slot one level higher than the spell’s actual level.
Spells whose ranges are not defined by distance, as well as spells whose ranges are not close, medium, or long, do not have increased ranges.
ESCHEW MATERIALS [GENERAL]
Benefit: You can cast any spell that has a material component costing 1 gp or less without needing that component. (The casting of the spell still provokes attacks of opportunity as normal.) If the spell requires a material component that costs more than 1 gp, you must have the material component at hand to cast the spell, just as normal.
EXTEND SPELL [METAMAGIC]
Benefit: An extended spell lasts twice as long as normal. A spell with a duration of concentration, instantaneous, or permanent is not affected by this feat. An extended spell uses up a spell slot one level higher than the spell’s actual level.
GREATER SPELL FOCUS [GENERAL]
Choose a school of magic to which you already have applied the Spell Focus feat.
Benefit: Add +1 to the Difficulty Class for all saving throws against spells from the school of magic you select. This bonus stacks with the bonus from Spell Focus.
Special: You can gain this feat multiple times. Its effects do not stack. Each time you take the feat, it applies to a new school of magic to which you already have applied the Spell Focus feat.
GREATER SPELL PENETRATION [GENERAL]
Prerequisite: Spell Penetration.
Benefit: You get a +2 bonus on caster level checks (1d20 + caster level) made to overcome a creature’s spell resistance. This bonus stacks with the one from Spell Penetration.
IMPROVED COUNTERSPELL [GENERAL]
Benefit: When counterspelling, you may use a spell of the same school that is one or more spell levels higher than the target spell.
Normal: Without this feat, you may counter a spell only with the same spell or with a spell specifically designated as countering the target spell.
LIGHTNING REFLEXES [GENERAL]
Benefit: You get a +2 bonus on all Reflex saving throws.
MAGICAL APTITUDE [GENERAL]
Benefit: You get a +2 bonus on all Spellcraft checks and Use Magic Device checks.
MAXIMIZE SPELL [METAMAGIC]
Benefit: All variable, numeric effects of a spell modified by this feat are maximized. Saving throws and opposed rolls are not affected, nor are spells without random variables. A maximized spell uses up a spell slot three levels higher than the spell’s actual level.
An empowered, maximized spell gains the separate benefits of each feat: the maximum result plus one-half the normally rolled result.
QUICKEN SPELL [METAMAGIC]
Benefit: Casting a quickened spell is a free action. You can perform another action, even casting another spell, in the same round as you cast a quickened spell. You may cast only one quickened spell per round. A spell whose casting time is more than 1 full round action cannot be quickened. A quickened spell uses up a spell slot four levels higher than the spell’s actual level. Casting a quickened spell doesn’t provoke an attack of opportunity.
Special: This feat can’t be applied to any spell cast spontaneously (including sorcerer spells, bard spells, and cleric or druid spells cast spontaneously), since applying a metamagic feat to a spontaneously cast spell automatically increases the casting time to a full-round action.
RINN’S REFINED RUSE [TRICKY MAGIC]
Prerequisite: 1st level Rogue
Benefit: You may roll DC to cast a spell from the Illusion magic school without using an action. The DC is modified by your Dexterity modifier should the spell require any gestures, or modified by Intelligence modifier if it’s entirely verbal. The level of spells in restricted to your Magic user level divided by 2 rounded down. e.g, a level 3 Magic user can only cast spells using this feat of level 1 or 0.
Synergies: Combat Casting +2.

SCRIBE SCROLL [ITEM CREATION]
Prerequisite: Caster level 1st.
Benefit: You can create a scroll of any spell that you know. Scribing a scroll takes one day for each 1,000 gp in its base price. The base price of a scroll is its spell level x its caster level x 25 gp. To scribe a scroll, you must spend 1/25 of this base price in XP and use up raw materials costing one-half of this base price.
Any scroll that stores a spell with a costly material component or an XP cost also carries a commensurate cost. In addition to the costs derived from the base price, you must expend the material component or pay the XP when scribing the scroll.
SILENT SPELL [METAMAGIC]
Benefit: A silent spell can be cast with no verbal components. Spells without verbal components are not affected. A silent spell uses up a spell slot one level higher than the spell’s actual level.
Special: Bard spells cannot be enhanced by this metamagic feat.
SPELL FOCUS [GENERAL]
Choose a school of magic.
Benefit: Add +1 to the Difficulty Class for all saving throws against spells from the school of magic you select.
Special: You can gain this feat multiple times. Its effects do not stack. Each time you take the feat, it applies to a new school of magic.
SPELL MASTERY [SPECIAL]
Prerequisite: Wizard level 1st.
Benefit: Each time you take this feat, choose a number of spells equal to your Intelligence modifier that you already know. From that point on, you can prepare these spells without referring to a spellbook.
Normal: Without this feat, you must use a spellbook to prepare all your spells, except read magic.
WIDEN SPELL [METAMAGIC]
Benefit: You can alter a burst, emanation, line, or spread shaped spell to increase its area. Any numeric measurements of the spell’s area increase by 100%.A widened spell uses up a spell slot three levels higher than the spell’s actual level.
Spells that do not have an area of one of these four sorts are not affected by this feat.
