You can activate staffs with the speed that an archer
fires arrows.

Prerequisites: Craft Staff, Master Staff, Quicken Spell, Spellcraft 30 ranks.

Benefits: You may activate a staff in place of an attack instead of as a standard action. As a full-round action, you could thus make as many staff activations as you could normally make ranged attacks. For instance, if your base attack bonus is +11, you could activate a staff three times as a full-round action. If you also had the Rapid Shot feat, you could activate the staff four times as a full-round action.

Each activation after the first costs one additional charge from the staff, cumulative. Thus, the second activation in a round costs 2 extra charges, the third activation 3 extra charges, and so forth.

You can activate wands with the speed that an archer fires arrows.

Prerequisites: Craft Wand, Master Wand, Quicken Spell, Spellcraft 25 ranks.

Benefits: You may activate a wand in place of an attack instead of as a standard action. As a full-round action, you could thus make as many wand activations as you could normally make ranged attacks. For instance, if your base attack bonus is +11, you could activate a wand three times as a full-round action. If you also had the Rapid Shot feat, you could activate the wand four times as a full-round action.

Each activation after the first costs one additional charge from the wand, cumulative. Thus, the second activation in a round costs 2 extra charges, the third activation 3 extra charges, and so forth.

Dwarves cannot use these.

You can make a spell affect an incredibly large area.
Prerequisites: Enlarge Spell, Encompassing Spell, Grow Spell, High Magic
Benefit: The character can increase a spell’s area to a mile. A massive spell uses up a spell slot six levels higher than the spell’s actual level. See the full rules for elven High Magic in the Magic of the Elves chapter.

[Reference: The Quintessential Elf; Page 53]

You have learned the secrets of elven High Magic.
Prerequisites: Spellcaster level 9th
Benefit: The character can suffer a temporary point of Constitution damage in place of one higher level slot to power spells cast with a metamagic feat. The lost Constitution points cannot be regained by any magical means; only rest will bring them back. See the full rules for elven High Magic in the Magic of the Elves chapter.
Special: The character must have this feat in order to learn any of the High Magic abilities.

[Reference: The Quintessential Elf; Page 52]

Your spells can affect a greater area of number of targets.

Benefit: A grown spell has its area or number of targets affected increased by one-half. Spells with a personal affect or that target only a single creature are not affected. A grown spell uses up a spell slot two levels higher than the spell’s actual level.

[Reference: Quintessential Elf; Page 52]

Using your skill with magic, you absorb a magic item into your body, taking on its essence and powers.

Prerequisite: Charisma 19, caster level 10th

Benefit: You can absorb a magic item and make its powers inherent within you. You cannot fuse with magic weapons or armor, nor can you fuse with potions or scrolls. You can fuse with any other item. Activating or using an item that’s fused with you works the same as for a normal item. A fused wand of wall of ice allows you to cast wall of ice as a spell-like ability (using the item’s caster level) 50 times, or however many charges it had left at the time of the fusing. Bonus types do not change. A fused amulet of health +4 grants you a permanent enhancement bonus (not an inherent bonus) of +4.

Fusing with an item first requires an XP cost equal to half the item’s gold-piece value. Then, you must make a Spellcraft check with DC 20 + the item’s caster level for each of the item’s separate abilities. Failure means that you cannot use that power. You may try only once per ability. Even if you are unable to use any of the powers of a fused item, the item is consumed, and the experience points lost.

Once consumed, a fused item cannot be taken away from you. It does not need to be drawn or wielded, and it is not visible in any way. It takes up no space on your body, so if you have fused with an amulet you can wear another amulet with- out problems. Like all spell-like abilities, using the fused item requires no components and draws no attack of opportunity.

Items that logically grant no benefit from being absorbed— mainly because their power comes from being independent of the user, such as a figurine of wondrous power or dust of tracelessness—cannot be fused.
Mord’s disjunction removes the item from you, restoring it to its normal state.

Intelligent Items: Fusing with an intelligent item forces you to make a Will save at the beginning of each day (DC 10 + item’s level + item’s Charisma bonus). If you succeed, you are in control for the day and can use the item’s abilities, skills, and feats (if applicable). If you fail, the item remains in control of you for the day and can use your abilities, skills, and feats. Items fused with a character cannot gain levels as described on page 63.

You can create items using the knowledge gained from all of your spellcasting classes.

Prerequisite: Any item creation feat, able to cast spells from two different spell lists.
Benefit: When acquiring item creation feats or when creating magic items, you can add together the caster levels of all your spellcasting classes to determine your caster level. For example, a 1st-level bard/1st-level cleric/3rd-level wizard could gain Craft Wand and create magic items as a 5th-level caster.

Your research has unlocked a new power in conjunction with using a wand.

Prerequisite: You must be at least an 11th-level Wizard and must have the Craft Staff feat to select this discovery.

Benefit: Similar to using a magic staff, you use your own Intelligence score and relevant feats to set the DC for saves against spells you cast from a wand, and you can use your caster level when activating the power of a wand if it’s higher than the caster level of the wand.

Prerequisites: Dwarf, hardy racial trait.

Benefit: You receive a +4 racial bonus on saving throws against spells and spell-like abilities. This replaces the normal bonus from the dwarf’s hardy racial trait.

At 7th level, once per day as an immediate action, you may reroll a failed save versus a spell or spell-like ability.

At 14th level, whenever you would take half damage from a spell or spell-like effect, you instead take ¼ damage.

Normal: Dwarves normally receive a +2 racial bonus on saving throws against spells and spell-like abilities.

[Reference: TPK Games, Feats Reforged II, pg, 33]

Prerequisite: Spellcraft 10 ranks.
Benefit: When casting a selective spell with an area effect and a duration of instantaneous, you can choose a number of targets in the area equal to the ability score modifier used to determine bonus spells of the same type (Charisma for bards, oracles, paladins, sorcerers, and summoners; Intelligence for witches and wizards; Wisdom for clerics, druids, inquisitors, and rangers). These targets are excluded from the effects of your spell. A selective spell uses up a spell slot one level higher than the spell’s actual level.

Spells that do not have an area of effect do not benefit from this feat.
At 20th level, you may exclude double the normal number of targets.

[Reference: TPK Games, Feats Reforged II, pg, 29]

Prerequisite: Spell Focus

Benefit: Choose a spell school for which you have the Spell Focus feat. Your spells of that school have gain a +5 bonus to the DC needed to identify and to dispel them.

Special: You may take this feat multiple times. Each time you take this feat, it applies to a different school of magic.

[Reference: Kobold Press; The Complete Advanced Feats; Pg 19]

Transfer Spell (Metamagic)

You can change the range of a spell from personal to touch.

Benefit: You can use Transfer Spell with any spell that has a range of personal to change its range to touch. The target of the spell must accept the spell voluntarily or it has no effect.

Level Increase: +1

Reach Spell (Metamagic)
( Complete Divine, p. 84)

[Metamagic]

You can cast touch spells without touching the spell recipient.

Prerequisite

Benefit
You may cast a spell that normally has a range of touch at any distance up to 30 feet. The spell effectively becomes a ray, so you must succeed on a ranged touch attack to bestow the spell upon the recipient. A reach spell uses up a spell slot two levels higher than the spell’s actual level.

Level Increase: +2

Reference: https://dndtools.net/feats/complete-divine--56/reach-spell--2390/

You can daze creatures with the power of your spells.

Benefit: You can modify a spell to daze a creature damaged by the spell. When a creature takes damage from this spell, they become dazed for a number of rounds equal to the original level of the spell. If the spell allows a saving throw, a successful save negates the daze effect. If the spell does not allow a save, the target can make a Will save to negate the daze effect. If the spell effect also causes the creature to become dazed, the duration of this metamagic effect is added to the duration of the spell.

Level Increase: +3 (a dazing spell uses up a spell slot three levels higher than the spell’s actual level.

Spells that do not inflict damage do not benefit from this feat.

@halfgiant said in Kargin - Metamagic Notes:

Innate Spell [Metamagic]

You have mastered a spell so thoroughly that you can now cast it as a spell-like ability.

Prerequisites: Quicken Spell, Silent Spell, Still Spell.

Benefit: Choose a spell you can cast. You may now use this spell three times per day as a spell-like ability. If the innate spell has an XP cost, you pay the cost each time you use the spell. If it has a focus, you must have it to use the spell in this manner. If the innate spell has a costly material component, you need an item worth 50 times that amount to use as a focus for the spell-like ability. Otherwise, you need no components to use the innate spell as a spell-like ability.

You must permanently assign one spell slot of the appropriate spell level to the innate spell. You cannot use this spell slot for anything else.

Special: You can select this feat multiple times, selecting a new innate spell each time.

this is the little weenie version of the Fcheat… better one is in Complete Arcane p80

Actually, the complete arcane version takes a spell slot 8 level higher than the spell. Meaning it can only be use don 1st and second level spells.

Otherwise, I do not see a difference.

Persistent Spell
( Deities and Demigods, p. 51)

[Metamagic]

The deity makes one of its spells last all day.

Prerequisite: Extend Spell (PH) ,

Benefit
A persistent spell has a duration of 24 hours. The persistent spell must have a personal range or a fixed range (comprehend languages or detect magic, for example). The deity is still required to concentrate on spells such as detect magic and detect thoughts to use their effects. Concentrating on such a spell is a standard action that does not provoke an attack of opportunity. A persistent spell uses up a spell slot four levels higher than the spell’s actual level

according to complete arcane (p81) this is a +6 add for us mere mortals
Dregnoth glances probingly at Kargin to see if he’s stashed some Godsblood in his platemail

Your spells can affect more targets.

Benefit: A spell that normally affects a single target now affects 1 target /caster level, no two of which can be more than 30 ft. apart. A mass effect spell uses up a spell slot 4 levels higher than the spell’s actual level.

Special: If used with a touch spell, all targets must be in physical contact with one another. This feat does not work on spells with a range of “personal.”
