The Sun Blade was a powerful sword which presented itself at first glance as a sword-less golden hilt. Upon becoming attuned to its user, the blade emitted a pulsing radiant blade which could burn through its foes with ease. The sword's luminous blade emits bright light in a 15-foot radius and dim light for an additional 15 feet. The light is sunlight. While the blade persists, you can use an Action to expand or reduce its radius of bright and dim light by 5 feet each, to a maximum of 30 feet each or a minimum of 10 feet each.
