In addition, while you hold the sword, you have
resistance to fire damage. In freezing
temperatures, the blade sheds bright light in a
10-foot radius and dim light for an additional
10 feet. When you draw this weapon, you can
extinguish all nonmagical flames within 30 feet
of you. This property can be used no more than
once per hour.
