Sondur, the Burning Great Axe

+1 Great Axe.
You can use a Bonus Action to cause flames to erupt from the axe. It sheds bright light in a 40-foot radius and dim light for an additional 40 feet. While the axe is ablaze, it deals an extra 1d6 fire damage.
After dealing 30 killing blows to hostile enemies while in this form it transforms.
Using any other weapon to fight or face enemies causes it to revert to its original form.
Only one feeling comes to mind when you wield
this weapon... Hunger.
