A spell is a one-time magical
effect. Magic is used by individuals with magical power, which include spellcasters and creatures with spells and spell-like abilities. Spells can be arcane or divine.
Divine spells draw power from an unworldly source, be it from within the caster's own beliefs or some greater entity of power. Divine spellcasting requires meditation and provides more utilitarian effects, including the ability to heal the wounded. Some spells may be cast by both arcane and divine caster, functioning as
arcane spells when cast by arcane casters and
divine spells when cast by divine casters.
Most spells require the caster to speak some utterance, make complex gestures, or sometimes expend an object or a small quantity of some substance. The spellcaster's activity is visible to others, and the effects often are too, but the magic itself is not.
