Capsule of Zulf

Capsule of Zulf
Rare Reagent (1 gp)
Rank: 4
A thin clay capsule, made of two interlocking halves that seal together with a twist. When joined, etched runes arc with sparks, sealing the capsule as the alchemical inscriptions align.
Creation
A Capsule of Zulf can only be crafted within Alchemist’s Ground. The process begins with stabilized clay, mixed with a drop of Magic Essence, shaped into two cupped halves. Each half is inscribed with bisected runes of Zot, Gul, and Ef, which must align perfectly across the seam. The halves are then fired in a Froken Kiln until they harden to a fine, pale gray. Once cooled, they are left overnight in Still Air, bathed in Purple Rays, to attune the runes. Yield: 20 capsules.
Ingredients: Stabilized Clay, A Drop of Magic Essence (rare, 20gp)

Description

A Capsule of Zulf is a clay container roughly the size of a walnut, pale and semi-delicate. Each capsule is formed of two halves etched with mirrored runes, which spark faintly when twisted together. Once sealed, the capsule is airtight and stable, capable of holding volatile alchemical mixtures that would otherwise be unsafe to transport.

Lore

The craft of the Capsule of Zulf is said to have originated in the southern provinces, where alchemists first experimented with embedding runes into clay. Today, they are widely traded among serious practitioners, prized for their reliability. While inexpensive by alchemical standards, the capsules are considered essential for containing dangerous or unstable reagents. Alchemists often sell them in padded boxes of twenty, ready for filling.
