Rod of Endless Light

An arcane focus is a special item designed to channel the power of arcane spells. A sorcerer, warlock, or wizard can use such an item as a spellcasting focus. While holding this rod, you can use an action to speak its command word. When you do, the rod sheds bright light in a 20-foot radius and dim light for an additional 20 feet. The light remains for 1 hour or until you use an action speak the rod's command word again while holding it. For the duration, you can use a bonus action to mentally change the color of the light while holding the rod.
