This sword crackles with the fire of an ancient Brass dragon's breath when its special ability is activated. Once per day, the user can call on the energy from within the sword to summon this fire that follows the strokes and movements of the sword. This transmutation lasts 1 minute, and while it is active, hits with it during this time deal an extra 4d8 or 4d10 fire damage. During this time, the user also gains resistance to fire damage and gains true sight with a range of 60 ft. When hit by an attack with this weapon the target is lit on fire taking 1d6 damage at the beginning of their turn until you take an action to put it out. The sword also radiates 30ft of bright light and 30 ft of dim. 

The user must be attuned to gain any of these benefits. While attuned, the user and katana cannot be separated unwillingly. This sword is an artifact and cannot be destroyed unless an ancient silver dragon takes an action to absorb the magical energy from the sword, turning it into a normal longsword. 

Proficiency with a longsword allows you to add your proficiency bonus to the attack roll for any attack you make with it.

Notes: Bonus: Magic, Bonus: Dexterity Score, Twice Proficiency: Dexterity Attacks, Twice Proficiency: Dexterity Saving Throws, Weapon Property: Finesse, Weapon Property: Light, Bonus: Ability Score Maximum, During the Great Dragon's War in Shou Lung 9 children were born to a single set of parents, Hyoho, Muso, Tenshin, Mugai, Ono-ha, Yagyu, Jigen, Tamiya, and Tsuke. After the 9th was born the husband was called out to fight. He returned decorated, and as a master of the blade. As his children grew he begun to teach them the ways of the blade, and each took to it quickly. Each of them began to form their own blade techniques, and they quickly realized how the differences in children's fighting styles related to their personalities. They grew until they inevitably were brought into the war, each having to choose aside. While Muso, Tenshin, Mugai, and Yagyu went off to follow the Metalic dragons, their siblings went to follow the Chromatic. At first, the battles between siblings were great spectacles that would cause all around to stop their fighting to watch. However, Hyoho never drew his blade against one of his siblings seeking to find a middle ground between the two groups. Soon the siblings became too valuable to risk on the battlefield and each became advisers and champions to a different one of the dragons. Hyoho never stopped attempting to reunite his family, and after he had gained the ear of the Green dragon he began plotting a way to end the war. He went before the Green with a request to pull all troops out of the war and begin an era of peace once again. The Green's response was to slay Hyoho as a message to all cowards within his ranks. When the siblings learned of this they came together for the first time in several years to bury Hyoho and vowed to avenge him. Ono-ha, Jigen, Tamiya, and Tsuke helped their siblings to infiltrative the Chromatics' lair where together they slew the Green. Shocked at the loss of one of their own the Metallics proposed a way towards peace. That each of the now 8 dragons surrender their essence into the blades of these now 8 siblings allowing their essence to live on forever in the hands of masters of the blade. The Chromatics agreed in fear of how the 8 siblings and the Metallics could turn the war. So fearing for their lives and seeing a hope for immortality with never-ending rivers of blood they agreed. Thus each one of the 8 master's blades was imbued with the essence of dragons. Each master passed on their blade to a student when the blades determined that they were worthy as both blade master and person for what each sought to accomplish., By a Master of the Katana who has won the approval of the Brass Dragon, Versatile, Sap
