Battleaxe, uncommon 

You have a +2 bonus to attack and damage rolls made with this magic weapon.

You can attune to this weapon

While attuned, you gain the following benefits.

~ As a bonus action you can cause the axe’s head to burst into flames, casting Bright Light in a 20-foot radius and Dim Light for an additional 20 feet.

~ While the flames persist, attacks made with this weapon deal an extra 1d4 fire damage.

~ Additionally, while the flames persist, as a reaction when you take cold damage, you can gain resistance to the damage.

The flames persist indefinitely, until you use a bonus action to put out the flames or until you sheathe the weapon.
