Spellcraft is the art and craft of creating and casting spells.
Spellcraft honors the power of the well-crafted word. Once, it was perhaps comparable to oratory, a highly esteemed talent especially among honor societies, the ability to speak in a way that roused people to act, to think, to not think, to not act, according to your Will.
But spellcraft is more subtle as the words are not written or spoken to people, but to Nature, or the energetic Universe, in order to bring about a change.
Spells are spoken, often in accompaniment with other ritual actions and movements, in the privacy of the magic-user’s sacred space, rather than in a public place.
