Magic Materials

## Dendritic Crystal

This translucent blue and purple crystal is an invasive growing crystal that uses sunlight to regenerate its previous shape after being broken. Originally native only to the Elemental plane of air it has found its way to the Primer Material plane. The process for mining and cultivating the crystals is long and difficult, which makes Dendritic crystal very expensive.

### Armor and Weapons

Dendritic crystal is not usually made into weapons or armor for its enhancement abilities. Any item made of Dendritic crystal is much easier to shatter than an item made of steel. But the crystal’s ability to regenerate in sunlight means any item made of dendritic crystal will return it to pristine condition upon exposure to the sun, with the sunlight restoring 1 square foot of material per round.

## Dimeritium

Also known as the magician's bane, dimeritium is a dark blue metal with magic negating properties, often used to create restraints for spellcasters. Items made of dimeritium cannot be enchanted or magically enhanced. Dimeritium’s effects can be negated for as long as they are enclosed inside a lead container.

### Armor

Those who don armor made of Dimeritium succeed all saving throws versus spell effects, and spells that target them have no effect.

For as long as a creature wears dimeritium armor, they lose access to all spell slots and any spell-like abilities they had and the user's number of attunement slots drop to zero for as long as they wear the armor.

### Weapons

Weapons made of Dimeritium prevent the user from performing any magic attacks with them such as the paladin’s smite, Samurai’s Enpi, Monk’s Stunning strike, etc.

* Weapons made of Dimeritium can pass through magical barriers as though they were nonexistent, ignoring the effects of spells such as Shield and Mage armor.
* Dimeritium weapons can force spellcasters to make concentration checks when attacking a spell’s effect such as a Spiritual Weapon, Wall of fire or Bigby’s hand, for example.
* When a caster is struck by a dimeritium weapon, they calculate their concentration check DC to be 10 or the total damage taken, whichever is higher.

## Moon Steel

This dark, slightly translucent steel was created by the moon elves eons ago to cover and conceal their castles and defenses after nightfall. This material bends moonlight around it so as to make itself invisible during the night. It is created by forging the steel using only heat generated by concentrated moonlight, and must be quenched in distilled water in direct light of the full moon.

### Armor

Any creature wearing armor made of moon steel has advantage on dexterity (Stealth) checks when lit only by the light of the moon. Creatures wearing moon steel armor are also immune to the effects of the spell Moonbeam.

### Weapons

Weapons made of moon steel always count as magical for the purposes of bypassing resistances, and are invisible in the light of the moon. Any shapechanger struck by a weapon of moon steel must make a constitution saving throw, DC 10 or half the damage dealt, whichever is higher, or be forced to revert to their true form.

## Nevermelt Ice

Nevermelt ice is a special material that can only be created using Draconic magic to mix the schools of Conjuration and Transmutation. It is cold to the touch, but not as cold as standard ice and it doesn't melt unless subjected to temperatures above 200 degrees Fahrenheit, at which point it will slowly melt. At temperatures above 400 degrees it will melt rapidly.

### Uses

Nevermelt ice has no specific magical properties on its own besides the fact that it is ice than cannot melt under normal circumstances. It is sometimes used in Thal'Thaxia for the creation of weapons that deal frost damage.

(In mechanical terms, it functions like always cold stone that has vulnerability to fire.)

## Sun Steel

This Golden-White steel was created by the sun elves eons ago to beat back creatures of the shadowfell. This Material absorbs sunlight to be released as radiant energy. It is created by forging the steel using only concentrated sunlight and must be quenched in Holy Water on the summer solstice.

### Armor

Armor made of sun steel gives the user resistance to radiant damage, and the spell sunbeam has no effect on them.

### Weapons

Weapons made of Sun steel always count as magical for the purposes of bypassing resistances. Once per turn, when striking an undead creature, the user may add their charisma modifier (minimum 1) as radiant damage to the attack if they are in direct sunlight.
