A channel focus is a garment or other object that incorporates a holy symbol of a particular faith and counts as a divine focus of that faith. By spending a use of channel energy, a cleric (or other character with that ability) can trigger a special ability of the item. The spent channel has no effect except to activate the channel focus. A channel focus can be reused many times. When not activated, the focus has no magical aura or abilities. Unless otherwise stated, an activated channel focus can be used by any member of the indicated faith, even if he wasn’t the one who activated it.
