This entry indicates what the character must have or do to cast the spell. If the necessary components are not present, the casting fails. Spells can have verbal (V), somatic (S), material (M), focus (F), divine focus (DF), or experience point cost (XP) components, or any combination thereof.
If the material component, focus or define focus has an GP cost, the cost is listed; otherwise the character can assume that the actual materials involved are at the discretion of the caster and have no significant monetary value.
Material components are always consumed during the casting of a spell; a focus or divine focus is not. If a special focus or divine focus is required, it will be unique to the spell and cannot be used as the focus for other spells.
