The Iron Handbook is a non-denominational collection of spells and wards designed to drive away the fey. The authors of the book clearly disliked all fey, and viewed any trafficing with them as foolhardy at best, and traitorous at worst. The following spells (as described in the PHB) can be found within this heavy, gray, iron-bound tome: break enchantment, dispel magic, dispel magic (greater), protection from spells, remove curse, spell turning, and true seeing.

The Handbook also contains the following new (or new-ish) spells:

Circle of Iron: as undeath to death, but with the following changes...
- Replace all instances of "undead" with "fey".
Material Component: The powder of a crushed diamond with at least 500 gp, mixed with an equal amount of powdered iron.

Cold-Iron Body: as iron body, but with the following changes...
Level: Clr 9, Sor/Wiz 9
- The recipient of this spell also gains complete immunity to the spells, spell-like abilities and supernatural abilities of the fey. Fey treat the caster as though he had the 'frightful presence' ability of a dragon (HD equal to the caster level), and are themselves treated as nauseated if within 30 feet of the caster (Fortitude save negates).

Cold-Iron Symbol, Greater: as symbol of death, but with the following changes...
- The spell only works against fey targets.
Material Component: Mercury, iron dust and lead dust, plus powdered diamond and jade with a total value of at least 4,000 gp each.

Cold-Iron Symbol, Lesser: as symbol of pain, but with the following changes...
Necromancy
- The spell only works against fey targets.
Material Component: Mercury, iron dust and lead dust, plus powdered diamond and jade with a total value of at least 800 gp.

Cold-Iron Wall: as wall of iron, but with the following changes...
Level: Clr 7, Sor/Wiz 7
- The wall is complete immune to the spells, spell-like abilities and supernatural abilities of the fey. All fey within 15' of the wall are nauseated, unless they make a successful Fortitude save

Detect Fey: as detect undead, but with the following changes...
Level: Brd 1, Clr 1, Drd 1, Rng 1, Sor/Wiz 1
- Replace all instances of "undead" with "fey".

Ferrous Cloak: as cloak of chaos, but with the following changes...
Abjuration
Level: Clr 8, Sor/Wiz 8
- A cold, dark gray haze surrounds the subjects, protecting them from attacks, granting them resistance to spells cast by fey creatures, and causing fey creatures that strike the subjects to become nauseated (replace all other instances of "lawful" or "law" with "fey").
Focus: A cold-iron cross made from four large nails, that has been soaked in fey blood for a full night, then sprinkled with 500 gp of powdered diamond.

Hide from Fey: as hide from undead, but with the following changes...
Level: Brd 1, Clr 1, Drd 1, Rng 1, Sor/Wiz 1
- Replace all instances of "undead" with "fey".

Iron Censure: as dictum, but with the following changes...
Evocation [Sonic]
Level: Clr 8, Sor/Wiz 8
- Replace all instances of "non-lawful" with "fey"

Iron Strike: as finger of death, but with the following changes...
Level: Clr 7, Sor/Wiz 6
Target: One fey creature
- You can slay any one fey within range.

Magic Circle against Fey: as magic circle against evil, but with the following changes...
Abjuration
Level: Brd 3, Clr 3, Drd 3, Pal 3, Rng 3, Sor/Wiz 3
- Replace all instances of "evil" with "fey".

Protection from Fey: as protection from evil, but with the following changes...
Abjuration
Level: Brd 1, Clr 1, Drd 1, Pal 1, Rng 1, Sor/Wiz 1
- Replace all instances of "evil" with "fey".

Toll the Iron Bell: as power word kill, but with the following changes...
Necromancy [Death, Sonic]
LV: Clr 9, Sor/Wiz 9
- You open your mouth and emit a loud, deep pealing note, like a great bell (replace "living creature" with "fey").

I like it, with two caveats:

(1) The format ought to be the standard "variant spell format" that WotC uses; see the detect spells. For instance:

Circle of Iron
Necromancy
Level: Clr 6, Sor/Wiz 6

This spell funstions as undeath to death, except that it affects fey instead of undead.

Material Component: The powder of a crushed diamond with at least 500 gp, mixed with an equal amount of powdered iron.

(2) Who originally wrote The Iron Handbook? I want to know more about the authors, why they hate the fey, what their group's like, etc. In short: more fluff!

I intentionally left it vague to fit into anyone's campaign. Honestly, I don't have any fluff for it. Though, I guess I could turn my mind to the task...let me give it some thought.

It is said that the Order of the Iron Helm was actually founded by a young human ranger, from a rural, frontier community. This ranger, Harrin Bartleby by name, lived with his kind, beautiful wife, Esmira, and their four healthy, cheerful children. They were poor, but quite happy and wanting for nothing. One day, Harrin returned from hunting to find that his wife and youngest daughter, a mere infant named Olette, were missing. His oldest child, himself only 4 years of age, could only tell his father a "pretty lady and man" came, then left with his mother and the babe.

For weeks he vainly searched for some sign. A month after her disappearance, just as dawn broke, he found Esmira wandering in a field a few miles from their home. The light of reason was extinguised from her eyes, and she was naked, save for colorful ribbons in her hair and a bell around her neck. The ribbons turned to mist in the first rays of the sun.

She never spoke or even responded to anyone ever again. Harrin cared for her for four more years before she finally passed on, a wasted shell. He never found Olette, though he never stopped searching. It was easy to see that the fey were responsible for the abductions, so Harrin learned all he could about combating them. As he gained skill, he became quited renown as a slayer of fey, and several communities discreetly sought his services.

All things mortal end, as did Harrin...one night, a full two score years after his wife first vanished, he just vanished as well. For many years after, on the night of the anniversary of his disappearance, a single piece of his gear would turn up on the grounds near his home. No one ever saw who or what was leaving the gear.

His children; Spencer, the oldest, and the twins Yevenne and Graydin, followed in their father's footsteps. Spencer...better known as Bartleby the Grim, or the Iron Squire...studied arcane magic, and became a rather powerful wizard. It is he that authored most of the spells found in the Iron Handbook. Graydin became a smith, specializing in fashioning items of cold-iron. He was a true master of the medium, quickly producing quality cold-iron items of all sorts. Yevenne became a ranger, like her father. It is she who first organized and named their movement the Order of the Iron Helm. She also worked extensively to recruit many new members and gain patrons. Finally, she was a master manipulator, expert at using propoganda and paranoia to whip up fear amongst the mortal population. Fear against all things fey.

Very nice background...I can see 6 or 8 adventure hooks in it already.

The thing about this sort of fluff is, it's easy to ignore if I as a GM want to substitute my own, but even if I choose not to use it, it's a terrific idea resource.

Nice. It had to be done... a list of anti-fey spells... T_T

All we need now are pro-Fey spells.... they seem to be lacking in most Fey material..

I also have a grudge: in some recent D&D book, Complete Mage, they once again split spells into 2 groups: Seelie and Unseelie. This shouldn't be done, as the two clans/houses/nations should not limit themselves by technique!
They should have THE SAME OPTIONS availible, and use whichever ones fit the situations. No need to restrict by assumed strict shools-of-thought... so limiting, so pointless...

Why not? If they don't do things differently, what is the point of distinguishing them?

They could do thigns differently. But what I meant is that they way WOTC presented the two clans is like racial differences, like between Devil and Demon or various types of Celestial.
If, say, Seelie was allowed Cure and Resurecctive spells and Unseelie were not for ANY reason, that severely hampers their capability to exist as successful fantasy D&D culture. Things like that may be associated by 'flavor' but have an essential function.
That's what I'm against.
Also, a Fey switching from one clan to the other won't have to redo their entire spell list, and I don't just mean S/Uns but between any other clan (jeez we need to put some more clans out there...)

Well, if you'd look at my Fey Courts thread, you'll see that I'm working on developing other "clans" (hint, hint, nudge, nudge)

Yeah I saw. The seasonal ones, right? Or are there more now? -_-;;

I saw about 8-9 in the Book of Fey by Green Ronin, and while they were seperated but ethos and sometimes by races cleanly, there really was no reason for their seperation or alliances between each other, nor any association with natural occurances.

There are more, and I'd greatly appreciate your comments.
