In AD&D 2nd edition, certain spells require different types of components to work. V, S, and M (Verbal, Somatic, Material). When material components, are required, these are listed in the spell description. Spell components are expended as the spell is cast, unless otherwise noted. Clerical holy symbols are not lost when a spell is cast. For cases in which material components are expended at the end of the spell (free action, shapechange, etc.) premature destruction of the components ends the spell.
