Ashbound (Eberron Campaign Setting 50) - Requires the ability to spontaneously cast summon nature's allyEFFECT:
Summon nature's ally summonlings get +3 accuracy and double duration.
Handy for all summoner Druids. If only it worked on
all class's summonlings!
Augment Elemental (Magic of Eberron 46) - Requires Knowledge (Planes) 2 RanksEFFECT: Elementals you summon get +2 enhancement accuracy and damage
and 2 temp HP/HD.
The sooner you take Augment Elemental, the better. It's a spiffy boost, but there may be far better feats for your caster in general by the time you could get this.
If you can take
Improved Elemental Summoning, take that instead!
Augment Summoning - Requires Spell Focus: Conjuration OR Enhanced Summoning OR the Dragon Below Domain (Eberron Campaign Setting 106)EFFECT:
ALL your summonlings get +4 enhancement STR and +4 enhancement CON.
ALL Elemental summoners need this, and Augment Summoning is an expected part of any summoner build!
Divine Metamagic (Complete Divine 80) - Requires another metamagic feat, the ability to cast divine spells, and the ability to turn or rebuke undeadEFFECT: Apply Divine Metamagic to another metamagic feat you know. At cast time, you can spend turn attempts equal to 1 + the metamagic's slot level adjustment to cast this spell with no slot adjustment.
Best effects: Heigthen for reserve feats (but see Controversies, below), Persistent for buffs and 24 hour-long Summon Elemental pets, and Quicken for extra in-combat actions.
Easy Metamagic [Metamagic] ("Dragon #325") - Requires another metamagic featEFFECT: One metamagic feat you know has its slot cost reduced by 1 (minimum +1 slot level).
Handy with Quicken and Persist. Nasty on
Fell Drain (
Libris Mortis 27).
Fell Drain [Metamagic] (Libris Mortis 27)EFFECT: Whenever your spell does damage, it also inflicts a negative level. +2 slot levels
Suddenly, that flock of low-level summons is a
lot more deadly! Couple with Easy Metamagic or Practical Metamagic to make this feat practical. Combine with Metamagic School Focus to reduce costs to +0 on occasion
Heighten Spell EFFECT: Spells are in all regards considered a spell of this higher level. Use it to meet prereqs early.
Combine with
Divine Metamagic or
Metamagic School Focus to qualify for reserve feats early, like
Summon Elemental at L1.
Using Divine Metamagic (Heighten) for early entry is debatable, however.
Improved Elemental Summoning (Homebrew) - Requires Knowledge (Planes) 2 RanksEFFECT: Most Elementals you summon are one step up (Greater instead of Huge, for example)
and you can summon more of them at a time.
I made this feat because I tired of Elementals being ineffective by the time I could summon them. Here you go!
Imbued Summoning [Metamagic] - Requires Augment Summoning and Spell Focus: ConjurationEFFECT: When you summon a creature, it's instantly buffed with a L3- melee touch spell you have prepared, +1 spell slot level.
As-is, you're spending a low level touch range buff spell
and a higher level slot for your summonlings
and and action and possibly a spell slot to summon something. There are times when this is useful, but save this for the spontaneous casters built for it.
If you can bypass the spell slot level adjustment, this feat is
black. If you can bypass the slot adjustment, the buff spell level restriction, and the buff spell range constraint, this feat is
navy.
Improved Initiative [Fighter]EFFECT: +4 initiative.
If you go first, you are guaranteed a turn! Start the fight off right by your uber initiative!
Invisible Spell [Metamagic] (Cityscape 27), Requires another metamagic featEFFECT: Your summonlings and other spell effects are invisible akin to
greater invisibility! +0 slot levels!
Whoever wrote this feat probably didn't expect invisible summonlings. Most
Monster Manual or stock creatures would need
true seeing, blinsight, or blindsense to detect your summonling. Wow!
Invisible creatures attack against flat-foot AC and get +2 accuracy.
Metamagic School Focus: Conjuration - Requires Spell Focus: Conjuration OR a that you be a ConjurerEFFECT: 3/day reduce the cost of a metamagic feat you know by 1 slot level to a minimum of +0 slot levels.
Woohoo! Heighten Spell with this feat makes spamming the Summon Elemental reserve feat possible!
This feat is still useful in the expected sense. Apply it to
Fell Drain to make your summonlings bestow negative levels. Use it on
Imbued Summoning to make Imbued Summoning less burdensome.
I'm sure you can find some other uses for this feat.
Persistent Spell (Complete Arcane 81) - Requires Extend SpellEFFECT: Spells you cast with a fixed range or a personal range instead last 24 hours. +6 (!) slot levels
1: Ask your DM if "touch" spells work with this feat. If so, its rating goes up
greatly.
2: If you can avoid paying more spell slots or higher level spell slots,
this feat is wonderful! See Incantatrix's Cooperative Metamagic and Metamagic Effect abilities and the feat
Divine Metamagic for details.
If you
can't avoid such costs, you must either greatly reduce this feat's slot adjustment or ignore it. +6 slot levels is almost never worth it!
Practical Metamagic [Metamagic] (Races of the Dragon 101) - Requires (Dragonblood) subtype, Spellcraft 8 Ranks, a metamagic feat, and the ability to spontaneously cast L3 spellsEFFECT: One metamagic feat you know has its slot cost reduced by 1 (minimum +1 slot level).
Handy with Quicken and Persist. Go
Dragonborn to meet the Dragonblood prereq.
Practiced Spellcaster (Eberron Campaign Setting 50) - Requires Spellcraft 4 RanksEFFECT: Your caster level in the chosen class increases by 4 to a maximum of your HD.
This is slightly helpful for Malconvokers. Combine with
Spellgifted for best effect.
Quicken SpellEFFECT: You can cast spells with a casting time of 1 round or less as swift actions. +4 slot levels
Best used on buffs or crowd control spells once you can cast level 5 or 6 spells. Wizards are known for having a blah level 6 spell selection, at least in core.
The
black rating is from needing to wait so long, and from which spells you cast with it.
Rashemi Elemental Summoning (Unapproachable East 45) - Requires Spellcaster Level 5EFFECT: Air elementals you summon gain the Orglash template, allowing them to cast
cone of cold 3/day, among other things. Your summoned earth elementals gain the Thomil template, granting them slight defensive bonuses (+2 natural AC, DR 10/magic, cold resist 5, and SR of 5 + their HD) and some other goodies.
With the Summon Elemental reserve feat, air elementals become blasters! Stay out of their way or use
anticold sphere (
Spell Compendium 13) to become cold damage immune.
Summon Elemental [Reserve] (Complete Mage 47) - Requires L4 Spellcasting and a spell slot dedicated to a summoning spellEFFECT: You can spam a Small true Elemental (water, air, fire, or earth) with a 30' tether. (Seemingly, this is
not any creature with the Elemental type, but a Water Elemental, an Air Elemental, a Fire Elemental, or an Earth Elemental.) This creature's duration is 1 round of the highest level summoning spell you have in resesrve. This increases to a Medium Elemental with a L6 spell and a Large Elemental with a L8 spell.
One of the major
points of this guide is using the reserve Elemental ASAP! Combine this feat with
Heighten Spell and
Metamagic School Focus: Conjuration to start spamming Elementals at level 1!
Water Devotion (Complete Champion 64)EFFECT: Once per day as a standard action (and more if you ignore
Complete Champion errata), any character can dump out a full waterskin to summon a Small water elemental for 1 minute. This Elemental becomes Medium at L6, Large at L11, and Huge at L16.
This feat is cool! Now
anyone can summon a water elemental, if only for a short time! Since it's summoned, other summon boosters (just about everything in this guide) apply.
If you play with
Complete Champion errata, you're limited to using this feat 1/day. You
can retake the feat to gain another daily use each time, but it ain't worth it.
If you ignore the errata (which I recommend), you can spend a turn or rebuke undead attempt to summon another water elemental.
