Because like Tieflings, Assimir and Genasi they still have mortal choice to live their lives in accordance with their own desires not fey nature.

Yet nature can't be completely ignored now can it?
I have a Tiefling character with Demonic ancestory, very unlogical for him to become utterly lawful. (Best working example I have. As I've never cared for Half-Feys.)

I suggest if you are looking to create a character, then take a look at multiple resources, or send me a PM and I'll toss you something back when I have the time to let you know what I think.

On lures and banes, I have some on my feytouched. However I don't make them as binding as I would for a fey. Say the feytouched is lured by fenberries. If it is clearly a dangerous situation or a trap he/she will be able to resist the temptation where a full-blooded fey might just not be able to.

Elves would be the most common and due to their similar nature, might arguably the most likely to manifest feytouch...edness.

Reminds me of something you said a long time ago about elemental blood only manifesting some of the time in genasi. Do feytouched follow the same pattern? As in a elf with no fey characteristics but a distant fey ancestor could produce a feytouched child?

(Sorry for what feels like a never ending stream of questions, just can't seem to find the answers anywhere else.)

I think when it comes to using elf as the base for fey touched its because it best represents the fey touched fey appearance, they aren't elves just elf is the best way to approximate the appearance. Just remember if the blood is too thin why not just play a Sorcerer with fey heritage and a strong love for their very distant fey ancestry.

Feytouched are a widely varied group of beings -- some are wispy and beautiful, while others are ugly and brutish. Some resemble elves, with pointed ears and almond-shaped eyes. Others look more like trolls, with warty skin and disproportioned limbs. Regardless, all feytouched have at least one feature or characteristic that is out of the norm -- vibrantly colored hair, feathered eyebrows, or a propensity for speaking in rhyme, for example. Despite their actual appearance, all feytouched are highly charismatic beings that draw attention wherever they go.

sometimes they just might not work at all, what is a bane to one fey might not be a bane to another. The problem also with lures and banes is that it's only documented in Bastion Press which is D20. So, it wouldn't surprise me if some of the fey player base doesn't even know about them, or if Selvac will even say if they work or not on Amia. It won't stop my main from believing the superstitions though.

Lures
The climate and terrain must be appropriate for a given
fey to be attracted by its particular lure. It is a mystery
how the fey become aware of a lure placed out for them,
but if the proper steps are taken, they will eventually
appear.

Alcohol: The finest wines, ales, and meads are an easy
way to draw satyrs, korred, fauns, and especially cask
imps.

Black Sand: When placed inside of a large opalescent
seashell outside the mouth of a sea cave, black volcanic
sand somehow attracts water-living and water-loving fey.
Blackberry Brambles: Blackberry brambles are the
home to many small fey creatures, most notably bogies
and fairies. Because of the associations with these fey races,
some cultures forbid people to eat blackberries. Many
academics feel that the berries are a delicacy among free
bogies.

Blackthorn: For reasons not shared with mortals,
faeries hold this plant sacred. The Luantishees are
blackthorn fairies.

Bluebell Flowers: Fairies dangerously enchant fields
of bluebells in both Faerie and mortal lands. A favorite
prank among lesser fey is to make bluebells actually ring
like metal bells when disturbed either by wind or walkers
among them.

Bouquet of flowers: Sprites and pixies are drawn to
the scent and beauty of freshly bloomed flowers.
Cinnamon: Feeorin and faeries love cinnamon. They
frequently cook with it, wear perfumes infused with its
oil, and use its aroma to make a foul smelling area more
pleasing.

Clover: A four-leaf clover can break fairy spells.
Colorful Magics: Pixies and bogies are attracted to
brilliant flashes of light and color that detonate in the sky,
and illusions and lightning are more apt to attract them
than fire.

Conflict: Everything from a small skirmish to a fullscale
battle has a chance to draw the attentions of feeorin
and especially knights of the fey.
Flowers: Bundling fresh flowers together and casting
them into coastal water sometimes attracts sirines to the
shore.

Ginger: The fey, especially feeorin, love ginger. Baked
into cookies, it is an especially soothing treat. Consumed
raw, however, it has been observed to be extremely
intoxicating to mortals but far more so to faeries.

Hollow trees: In folklore, ancient, hollow trees [called
bull oaks in England, bell oaks in Scotland and Ireland]
are trees that stood in old sacred groves. They were often
believed to be the home of spirits, elves, fairies or demons.

Holly: While grown wild or in shrub rows, holly is
often only brought indoors as a seasonal decoration. Tiny
fairies are drawn to the natural decoration and use the holly
as shelter against the cold when outside. If faeries reside
in the holly before it is harvested, they could come into
homes unbidden within the holly boughs.

Love poems: Reading love poems aloud attracts any
fey within hearing distance.

Music: Like many of the arts, music is adored by the
fey. Great music, due to its aural nature, can draw fey from
afar to listen to the music and observe the performer.

Paintings: Beautiful portraits and colorful scenic
paintings hold many a feys’ interest as they marvel at the
skill and dedication it took to produce the work.

Primrose: While not a major lure, this flower has ties
with fey lore. It is a main component in extending the
durations of see invisible and second sight spells.
Primrose Ragwort: The springy and tough boughs and
vines of this plant are used as horses by fairies. Tales speak
of entire tribes of faeries uprooting an entire bramble and
galloping away collectively on it.

Rowan: A fire built from the wood of a rowan tree aids
in summoning fey creatures and enhancing divinations
about or by the same.

Sage: A bundle of fresh cut sage placed in the crook of
a tree will attract any dryads that might be in the area.

Salt: Thrown across the face of a glacier, salt attracts
fey with an Aspect of Winter.

St. John’s Wort: This herb protects the bearer against
fairy spells if worn either freshly cut or dried. This also
increases the effectiveness of dismiss fey spells.

Willow: The wind in the willows is the whisperings of
a fairy in the ear of a poet. Conversely, talking, singing, or
scrying beneath a willow tree has a greater chance of
attracting fey attentions.

Writing Implements: Bogies, pixies, and sprites find
the process of writing fascinating, and will try their hand
at it if no one is looking. Thus, any desk or scriptorium has
a chance of gaining a faerie’s interest.

Banes

With fey interests being so naturally mercurial, it is hard
to say exactly what will or will not prevent them from
entering an area or doing something. Still, like garlic
against vampires, many things evoke natural revulsions
from the fey. Other things could be more individual due
to events of the past; some fey might hate all dwarves if a
dwarf once tricked their ruler out of a treasure. Unlike the
lures above, fey rarely become aware of a bane until they
are close enough to note its presence with mundane senses.
There are also a few noted substances useful for spells
against the fey.

Alder wood: This wood is an effective adjunct
component in the casting of dismiss fey, it increases the
effectiveness of the spell

Ash berries: Placing ash berries beside a sleeping child
decreases the chances that they will be attacked by a fey
from Between. Some scholars think the smell drives away
the fey.

Bells: When attached to the legs of dancers, ringing
bells can drive away fey creatures.

Birch wood: A tool containing parts made of birch
wood reduces the chance that a mischievous fey will
disturb, misplace, or steal one’s tools.
Clothing: The act of wearing clothes turned inside out
disgusts most fey. An inside out glove tossed into a fey
ring dance forces fey to make a concentration check to
maintain the revel. Wear odd socks or turn your sweaters
inside out, and fey are less apt to approach or disturb you.
“Turn your clokes for fairy folks are in old oakes” suggests
that turning a coat or cloak inside out can help to neutralize
fey magics or perhaps reveal their presence within the
sweep of a cloak.

Cold Iron: The much-storied “death at the touch of cold
iron” for faeries is true to a point. A dagger or an iron
spike in your pocket is enough to deter any fey who might
consider interrupting your sleep. Open scissors tied above
a baby’s crib (points and blades directed up and away) is
threatening enough to hold fey at bay.

Cowslip Elder: Placing a child in an elder-wood cradle
could cause it to be pinched black and blue by fairies.
Whether they do this out of spite or not, faeries cannot
abduct a child from such a cradle.

Flax: Scattering seeds or stalks on the floor of a house
will keep a fey away. Purging Flax is also called Fairy Flax.
Holy objects: Clerical holy symbols and the prayers of
priests can repel a fey, as can holy water, prayer books,
religious reliquaries, and relics. Strangely, mold from holy
ground also repels fey creatures through both its presence
and its scent.

Red Ribbon: Red ribbons tied about the tails of
livestock or around the chests of infants dissuade the fey
from stealing them.

Salt: While fey like salt moderately as a spice, they
cannot cross a line of salt. Sprinkling an unbroken line of
salt around an object prevents a fey from disturbing or
touching something.

Silver: Carry silver coins in your pockets; holding them
helps a mortal resist any fairies that are trying to lead you
away. Throwing silver coins at faeries may cause them to
become scared and run away from you.

Water: The flow of running water sometimes stops the
Wild Hunt in its tracks, while salt water (best if from the
ocean) can sometimes hedge off spriggans.

Whistling: This drives fey creatures into fits of rage,
for while all fey can sing or dance or perform many
entertainments, they cannot whistle. fey are most jealous
of whistling above all mortal talents.
