Ku'uh Crystals (Koo ooh)

Tier: 2

Complexity: 8

Crafting Time: 3

Ku’uh crystals are various crystals formed by the deposition of the magics of Ethenrea. Formed from epic battles, the collision of planes, or by powerful Thaumaturgists, these crystals hold power that normal mortals seldom possess.

These crystals are used to make enchanted objects and magical items, most being everyday items like portable stove tops to elemental swords, as well as being essential for many magical alloys, such as Adamantite and Mythral.

All Ku’uh Crystals come with different qualities, which change the rarity of the items they can create.

Properties

Material Characteristics

Ku'uh crystals have perfect prismatic cleavage and are transparent to opaque that mildly glow with magical energy. The size of the crystal changes the power that the singular crystal can output, which is referred to as the crystal's quality. See below for the effects of each quality.

Quality	Rarity	Item Charges	Recharge	Price
Petty	Very Common	1d4	2 per short rest	10 gp per carat
Lesser	Common	1d6	3 per short rest	50 gp per carat
Middling	Uncommon	1d8	4 per short rest	100 gp per carat
Greater	Slightly Rare	1d10	5 per short rest	250 gp per carat
Grand	Rare	1d12	6 per short rest	500 gp per carat
Black	Very Rare	1d20	10 per short rest	1000 gp per carat

The last tier, dubbed “Black” Ku’uh Crystals are always slightly darker than their normal-hued counterparts, and are so powerful that anything that is created from one is considered an artifact.
