The material component was a basic part of casting most spells.[1]

A material component consisted of one or more physical objects or substances. Once the spell was cast, the material component was annihilated. However, a spellcaster could often use a focus to substitute for such components, and it would not be consumed by the spell. Casters who wielded priestly magic usually used a divine focus, which had higher spiritual significance than the standard focus.[1]
