The Brand

You can use a bonus action to speak this sword's command word, causing flames to erupt from the blade. These flames shed bright light in a 20-foot radius and dim light for an additional 10 feet. While the sword is ablaze, it deals an extra 1d6 fire damage
to any target it hits. The flames last until you use a bonus action to speak the command word again or until you drop or sheathe the sword.

This action cannot be used again until the next
dawn.
