Dragon Fire Axe

Forged by the legendary dwarven smith Graendal Granitefist, this magical great axe provides 1d4 additional fire damage on a hit, and scores a critical hit on a natural roll of 18-20. In addition, the great axe can be thrown for a ranged attack within 20ft, inflicting 1d12 damage (with no additional bonus) on a hit, and will return to its attuned owner on telepathic command. Also, upon speaking the command word, the silver blade of the axe glows in energy, creating a circle of Sunlight in all spaces adjacent to the wielder.
Proficiency with a great axe allows you to add your proficiency bonus to the attack roll for any melee attack you make with it.
This weapon also has the following mastery property:
Cleave. If you hit a creature with a melee attack roll using this weapon, you can make a melee attack roll with the weapon against a second creature within 5 feet of the first that is also within your reach. On a hit, the second creature takes the weapon’s damage, but don’t add your ability modifier to that damage unless that modifier is negative. You can make this extra attack only once per turn.
