Spell Component Pouch
A small, watertight leather belt pouch with many small compartments. A spellcaster with a spell component pouch is assumed to have all the material components and focuses she needs except those that have a listed cost, divine focuses, or focuses that wouldn’t fit in a pouch (such as the natural pool that a druid needs to look into to cast scrying).
