Spellcasting Focus

A spellcasting focus is a special item through which a spellcaster can channel the power of their spells. If a spell requires a focus, the caster must have a focus suitable for their class (as described in their class essentials). A spellcaster must have hand free to hold their spellcasting focus when they cast a spell, but it can be the same that he or she uses to perform somatic components.
