Material (M)

A Material component is a particular material used in a spell's casting, as specified in parentheses in the Components entry. These materials aren't consumed by the spell unless the spell's description states otherwise. The spellcaster must have a hand free to access them, but it can be the same hand used to perform Somatic components, if any.
If a spell doesn't consume its materials and doesn't specify a cost for them, a spellcaster can use a Component Pouch instead of providing the materials specified in the spell, or the spellcaster can substitute a Spellcasting Focus if the caster has a feature that allows that substitution. To use a Component Pouch, you must have a hand free to reach into it, and to use a Spellcasting Focus, you must hold it unless its description says otherwise.
