What is a spell?
A spell is a discrete magical effect, a single shaping
of the magical energies that suffuse the multiverse
into a specific, limited expression. In casting a spell,
the caster carefully plucks at the invisible strands of
raw magic suffusing the world, pins them in place in a
particular pattern, sets them vibrating in a specific way,
and then releases them to unleash the desired effect-in
most cases, all in the span of seconds.
