Sword of Armageddon (5e Equipment)

Weapon (any sword), legendary (requires attunement)

You gain a +1 bonus to attack and damage rolls with this magic weapon. While the sword is on your person, you also have resistance to fire damage.
Power of Fire. You can use a bonus action to speak this magic sword's command word, causing flames to erupt from the blade. These flames shed bright light in a 40‑foot radius and dim light for an additional 40 feet. While the sword is ablaze, it deals an extra 2d6 fire damage to any target it hits. The flames last until you use a bonus action to speak the command word again or until you drop or sheathe the sword.
Armageddon. This sword has 3 charges. While holding it, you can use an action to expend 1 charge and cast meteor swarm from it (save DC 19). This property can't be used again until the next dawn. The sword regains 1d3 expended charges yearly at the dawn of the new year.
