Skelding Seal

A Skelding Seal is a type of arcane craft ritual that places a small, subtle marking on an inanimate object. In particular a Skelding seal grants an object a magic-sustaining property, allowing spells of a particular kind that are cast upon it to last for much longer.

Uses
Skelding seals are omnipresent in places of common magical use, most commonly being found in the homes, academies, and districts of the wealthy. This is because the seals themselves are costly to produce due to a combination of expensive components and the rarity of those who can produce the effect.

A simple Skelding seal can sustain basic spells for up to one hundred times their normal length, with most cantrips being able to sustain indefinitely. Seals become increasingly inefficient as the power of the spell increases. One of the more common uses for this type of magic is to produce elements of lighting or decoration.
