These are some of the rare materials that are found among the Estian Islands.

Gems

Each gemstone is linked with an element, a rune, a deity, and a school of magic.

Gemstone	Element	Rune	Deity	Magic School
Ruby	Fire	s Sowilo	Heimdall	Conjuration
Sapphire	Cold	i Isaz	Aegir	Abjuration
Amber	Thunder & Lightning	x Thurisaz:	Thor	Evocation
Emerald	Poison & Acid	k Kauna	Loki	Illusion
Zirconia	Force	g Getho	Tyr	Transmutation
Amethyst	Psychic	d Dagaz	Odin	Divination
Diamond/Luxite	Radiant	a Ansuz	Freya	Enchantment
Onyx/Noxite	Necrotic	k Pertho	Hel	Necromancy

A gem of the correct type might be the component to an elemental spell, crafting an item that harnesses the element, or as an offering to a god connected to that element or rune. Its color can vary from pale yellow, to almost red, to dark brown. It can even have small items or creatures encased inside, such as a flower or an insect. Pieces with well-preserved inclusions are very valuable, but very rare.

Amber

Though not a true gemstone, fossilised sap resin is an excellent carrier for lightning and thunder magic. It is most commonly found washed up on seashores, especially after storms. Emberholm, southwest of Salmy, is known for its amber workshops.

Luxite

An exceedingly rare prismatic form of diamond. Can produce very powerful enchantments, usually with a radiant or healing effect. Is found in chunks all over the world, as fallen from above. Sometimes called Shards of Bifrost after the great rainbow bridge that connects the planes. Some have theorised that Bifrost travel generates these crystals, and that is why they fall from the skies, but no mortal knows for sure. Luxite crystals can be used in place of diamonds as the material component to a spell.

Noxite

A luxite gem that absorbs too much negative energy can turn into noxite. This gem seems to absorb light, making the area around it darker. The rituals to turn luxite into noxite are only known to the most powerful necromancers who find it supremely useful for channeling necrotic energy.

Lunarite

Also called Aenilisne, 'moon-glass', this gem gives off a continuous blue glow. It is made by elven artificers by capturing the light of the moon during midnight rituals. Tel Edhil is almost exclusively lit by lunarite lamps.

Elemental Cloths

The silk made from the cocoons of the fluxberry silkworm is highly susceptible to elemental enchantments. Fluxworms only thrive in wild magic zones, and harvesting them is dangerous work. Fluxsilk, as the raw cloth is known is difficult to work with, still containing some of the wild magic from where it grew. Fluxsilk thread is worth about a gold for a 10-foot length. A square foot of raw fluxsilk cloth can cost hundreds of gold. Raw fluxsilk is highly pearlescent, with pale hues ranging from pink and cyan to lime and yellow depending on the light.

With the right skill and materials, an enchanter could harness the energies in raw fluxsilk. The widely known elemental cloths are windsilk, firesilk, watersilk and stonesilk, but it is theorised that other versions might exist.

The Arbrintirel family of Cottenhorn holds a near-monopoly on the production of raw fluxsilk, which has made them incredibly rich. While they do process some of it, they sell most of their product to other enchanters.

Windsilk

The most readily available of the elemental silks is windsilk. Threads of windsilk can be woven into a ship's sails which not only strengthens them, but also gives the ship the ability to sail far closer to upwind. Windsilk cloth is pure white, very light and flows around even in the lightest of winds.

Alyn Yunaes is the biggest producer of windsilk. Most of the production there goes to equip the Iacaris navy, but some is sold for a big profit. It is made by infusing fluxsilk with the essence of air elementals in wind tunnels.

Firesilk

Made by fusing powdered ruby to the cloth in a high-temperature process, firesilk is a rich crimson cloth. Gold filigree thread is usually added, which helps control the enchantment. A garment with firesilk threads is always pleasantly warm, and a firesilk napkin can also double as a cigar lighter (albeit a mighty expensive one).

Watersilk

Boiling fluxsilk in water from the elemental plane of water turns it into watersilk. This royal blue cloth absorbs dirt and other infectants and is self-cleaning, making it excellent for bandages and other medical applications. Threads of watersilk might also be woven into expensive clothes, which keeps them clean forever.

Stonesilk

If fluxsilk is dissolved in strong acids and then left to precipitate, the result is stonesilk, which becomes harder the more force is applied to it. Stonesilk is a light brown color, although impurities in the manufacturing usually gives it splotches of blacks and greens. It can be wrapped around something soft but will not yield if impacted with force. A robe made from stonesilk is as impervious to weapons as chainmail. The process to make and work stonesilk is expensive, time-consuming and lossy, and it can't produce thread, only sheets of cloth. Whoever comes up with a better process is sure to make a boatload of gold.

Shadowsilk

When fluxsilk is subjected to a large amount of negative energy, it is infused with the magic of the Shadowfell and is called Shadowsilk. It is a wispy black cloth that is favored by those who wish to perform necromantic enchantments.

Glimmersilk

If fluxsilk is blessed with radiant energy, the fibers take on the radiance of the sun. This form is called Glimmersilk and is very rare, requiring the aid of powerful extra-planar forces to create. Glimmersilk is brilliant white, impossible to tarnish, and subtly glows in darkness. It readily accepts enchantments, making even scraps of the material extremely expensive. It is extremely rare to see large sheets of Glimmersilk, with ribbon being the least rare form. Monks who follow the Way of the Sun Soul treasure this material over all others, as their powers come from a similar source.

Metals and composites

Sky Iron

Rarely, lumps of pure iron is found that appear to have fallen from the sky. The lumps fall more often in mountainous terrain, or at least that is where it is easiest to find. This dark, almost black form of iron is very hard to forge. Only the dwarven smiths of the mountain tribes craft have mastered the methods of reshaping it. Some of the sharpest blades in existence are made from this exceedingly rare metal. Items made from sky iron is always icy cold to the touch, even to the point of frosting up on a warm summer day. The ancient heirloom of the Grungiburgi tribe, the Runewarden, is made from sky iron.

Ashresin

Ashresin is a made from the byproducts of alchemical studies. If the right materials are burnt, the ashes can be bonded with hard resins in molds to form black plates. These plates are extremely tough and light. They also absorb magical energy from an impact. This makes them highly sought after as armor plates, especially by those who expect to face magic users, and as protective gear for arcane experimentation.

The best ashresin is made by the Archivists, especially in their Aphenor laboratories. They sell it by the sheet for outrageous prices. A full plate armor suit of good ashresin costs upward of 50000 gp.

Unstable compounds

Hydrium

A metal that burns with a very bright blue-ish flame. It is harvested from seawater, as a byproduct of making salt. In powdered form, it can be used as an explosive, although not a very powerful one. Hydrium explosives cause more noise and flash than any actual damage unless the explosion is contained.

Boomdust

A grey-ish highly explosive powder. It is made from a mix of guano and vitriol that is soaked into cotton rags. The Estian Compact currently has a monopoly on Boomdust, as it is only made in a single factory on Cottenhorn, which guards their production methods closely. The factory makes both loose powder for the Estian navy, and more specialized grenades, sapping charges and the like. It is highly illegal for civilians to own or use Boomdust.

Trees and Plants

Ironwood

A tree that grows as hard as metal, despite being very light. Extremely tough to work with, but can make very powerful bows. Large ironwood trees are rare, as it grows very slowly.

Poisonwood

A subtly magical wood, whose main characteristic is its capacity to be whittled in extremely fine shapes, including sharp edges. A blade is made from poisonwood leaves nasty wounds that fester easily.

Living Wood

Wood that has had strong druidic enchantments laid upon it to remain alive when harvested. An item made from living wood will slowly grow back missing parts, making it sought after for high-wear parts such as wheel axles and quarterstaves. It is very easy to break the enchantments when working living wood, and only a few masters can do it reliably.

Glowoak

A rare tree that only grows in forests connected to the feywild. Its seeds, called glowcorns, grow to be around 1 inch in size before they start to glow with a soft orange light, which usually happens in late autumn. A glowoak with all its glowcorns lit at night is a very beautiful sight, but one that only a few people ever get to see. Glowcorns are valued as a light source during wintertime, as they usually stay lit until spring. Shattering a glowcorn releases a splash of sticky, orange-glowing sap that fade over the next minute or so.

Glowcorn (weapon (sling bullet), uncommon): If you hit a creature with this bullet they must succeed on a DC 14 Dexterity saving throw or become coated in glowing sap, rendering them unable to go invisible, and granting advantage on attack rolls against them for one minute. A creature can use an Action to scrape off the sap from itself or another creature, ending the effect. You can also crush the Glowcorn in your hand, gaining the effect of the Light cantrip and consuming the Glowcorn.

Enchanted Glowcorn Lamp: (wondrous item, uncommon): Enchanted to capture the glow forever, it functions identically to a Driftglobe (opens new window).

Feyberry

A low bush with teal-colored leaves. It grows around Wild Magic zones. The berries are spherical, about one inch in diameter, pale blue and softly iridescent, and very sweet and juicy when ripe. Feyberry wood can also be used to channel magic through, making it a popular wood for wands.

See: Ripe Feyberry, Fluxfiber Conduit

Feverbush

A strongly-smelling plant that grows in swamps and jungles. Its bark is a ingredient in healing potions. If handled without proper precautions, it can make the wearer smell of feverbush for several days, a property that makes it useful also for perfume-makers.

Moonmint

A tea made from moonmint petals is an effective contraceptive, in both males and females. Moonmint grows as a vine in tall tree crowns, and its pale pink flowers only open during a full moon. There are many euphemisms for the herb and the tea made from it, including "bard's comfort" and "half-elf brew", referring to the fact that half-elves are infertile.

A moonmint flower worn openly signals that the wearer is a prostitute, and a stylized version of the flower is a widely recognized symbol for a brothel.

The great halfling painter Dominic Talonis was killed in a duel with Alastair Covington, an Aphenor nobleman after Talonis painted the nobleman's wife, Loretta Covington, with moonmint flowers in her hair. The portrait now hangs in the lobby of Covington's Wife, the premiere brothel in the inner circle of Aphenor.

Fire Laurel

Once dried, the succulent leaves of the fire laurel become hard as wood. When a dried leaf is cracked, it releases an oil that ignites upon contact with the air, making them very good fire-starters. Some people speculate that fire laurel only grows where a red dragon has fertilized the ground.

Fire Laurel Oil (very rare): A blade covered in this oil deals an additional 2d6 fire damage for one hour.

Silphium

Highly sought after as a spice when dried and powdered, this seaweed grows primarily on rapidly flowing riverbeds, making it very hard to harvest. Silphium divers are paid handsomely by the pound for herbs they deliver.

Ground Silphium (common): A small pinch of this powder makes almost any food taste good.

Noseweed or Whitemiss

A powerful aphrodisiac, usually consumed in a small piece of baked goods, giving them a pleasant tartness. It does not take much to have an effect, and taking too much is actively dangerous. It grows as low thorny bush on mountainsides, and harvesting the small bright blue berries requires some care, as it can absorb through the skin. As with moonmint, the plant has many nicknames and euphemisms surrounding whitemiss and its products, including "nobleman's aid", "all-night berries", and "blue-spark".

Whitemiss Extract (uncommon): This powder, when eaten, inflames the consumer with a nigh unsatiable lust for one hour. While this lasts, the victim has disadvantage on all wisdom saving throws and ability checks.

Icemoil

This bright blue flower grows in snowdrifts, usually high up on mountains or in tundra regions. If brought into warmer weather it quickly wilts, but it will keep indefinitely if kept cold. With the right techniques and equipment, the flowers can be turned into a powerful restorative serum. The flowers are also used to make Potions of Cold Resistance.

Serum of Icemoil (very rare): When applied to the skin of a creature, it gains the effect of the Greater Restoration spell.

Nettlerue

Nettlerue sap is highly venomous if injected. Harvesting the sap from this thorny bush is an exercise in carefulness. If the sap enters the bloodstream, victims can quickly fall into a comatose state, or even die. Nettlerue flowers are small and white, with three pointy petals.

Nettlerue Needles (rare): When a creature is hit with these darts, they must make a DC 14 Constitution saving throw or fall unconscious for 1d4 hours.

Buckliss Lily

The buckliss lily grows on battlefields, around slaughterhouses, and other places where blood has seeped into the ground. The large flowers are bright red, and traditionally given to nobles by their subjects as a sign of fealty. Several nobles houses have buckliss lilies in their coats of arms.

Dried buckliss root can be added to other potions or poisons to speed up their effects, as the buckliss seeks out blood while carrying the active ingredients.

Laceberries

Mildly magical plant, primarily grown for its sweet and very tasty berries. Laceberry jam is a favorite of many children, but it is only available in spring, when the berries ripen after wintering on the vines. Laceberries are white with little red seeds inside, and grows in low shrubs.

Bearnettle

Bearnettle leaves are a mild intoxicant when eaten, providing a subtle sense of euphoria. If over-consumed, it can lead to slowed down reflexes and sluggish movement, although it is generally not lethal. Dogs, bears, and other canids are especially fond of the plant and can smell it from far away. It is highly advised to not go between an owlbear and a patch of bearnettle.

Bearnettle Poison (uncommon): A highly concentrated decoction of bearnettle. When a creature is poisoned with this, they must make a DC 15 Constitution saving throw or become Poisoned for one hour. While they are poisoned, their movement speed is also halved.

Rawsley

The rawsley grows pale-green stalks with large iridescent flowers where the ground has been subjected to intense arcane magic. The flowers are a symbol of sorcerers, and the plant is sought after for its ability to restore magical energy to an imbiber.

Distilled Rawsley Essence (rare): Upon consumption, restores 2d4 sorcery points. A non-sorcerer who drinks this instead retches violently, taking 4d6 poison damage.

Rawsley Juice (uncommon): Upon consumption, regain an expended spell slot of up to 3rd level.

Azureroot

Azureroot is named for the bright colorful flowers that adorn its vines. It grows along stone buildings in warm climates, forming a dense blue-greenish carpet. Azureroot buds are used to cure many simple diseases, but it is not very powerful, needing several dozen buds for a single dose.

Azureroot Ointment (uncommon): When applied to a creature, it is cured of a disease.

Sanguine Milkcap

A mushroom that grows in lightless caves and cellars. While it is completely white on the outside, its juice is blood red, giving it its name. If cut, juice seeps out of the cut, allowing it to be harvested without picking the mushroom. If the juices are collected and dried before being ground, the remaining powder is a powerful drug called Sanguine Fizzle, which refreshes the user instantly, but causes a heavy hangover.
