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

Every dawn the weapon resets and gains 3 charges. Once, per day, if you receive lightning damage you regain 1 spent charge.

The wielder can choose to use any number of charges on a successful attack to deal an additional 1d8 of lightning damage and 1d8 of thunder damage.

While attuned to this item only you my wield it, otherwise it functions under the same physics as a mundane weapon that it was molded after being subject to gravity like normal, however, a creature can use an action to make a DC 30 Strength check, moving the hammer up to 10 feet on a success..

It does not add the 'heavy' property, however, it does add the 'light' & 'thrown' (20/60ft) properties, for the wielder, as long as you are attuned to it.

You can call the hammer back (if it is out of your grasp) as a bonus action, coming from where you threw the hammer, like the enemy you attacked, back to you in a straight line. Creatures of your choice in that line must make a DC 17 dexterity saving throw, or take 2d8 thunder damage.

Proficiency with a Maul allows you to add your proficiency bonus to the attack roll for any attack you make with it.
