Revised Battle Axe description

Frost Battle Axe of Rain Thana
Battle Axe, very rare (requires attunement), sentient item

When you hit with an attack using this magic sword, the target takes an extra 1d6 cold damage. 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.

Additional Special Abilities:
Heart of the Dragon: The axe grants advantage to the wielder against fire-based attacks.

Eye of the Wizard: It also has the ability to cast two spells, Charm Person (level 2), and Sleet Storm (level 3).

Voice of Command: The axe gives the wielder command over the battlefield. It has 6 charges that can be used to give inspiration dice to the wielder’s allies in combat (this is similar to a fighter’s superiority dice). The wielder can expend one charge as a bonus action by giving a command directing an ally’s action in combat. The charge grants +1d6 to that ally’s attack roll on the action suggested, and must be used within one round of the command. If the target chooses not to take the direction, they must make a saving throw (DC15) or take 1d6 psychic/cold damage from resisting the power of the suggestion. The wielder can also make a command directing the opponent’s action as well, with them making a saving throw (DC15) to shrug off the suggestion, taking the 1d6 psychic/cold damage on a successful save. The axe regains 1d6 expended charges each morning at dawn.

Dragon’s Curse: A curse was placed on the axe by its creators that makes it vulnerable to dragon breath. If the wielder is caught in the breath weapon of a dragon, have them make a saving throw for the weapon (DC10). If the weapon fails its save, the weapon explodes in a icy burst of 3d8 cold damage.
