Weapon (maul), Legendary

Ingredients: Chimeric lightning, Maul, Mithral chunk

You gain +1 bonus to attack and damage rolls made with this magic weapon.

Meteor Strike (Requires Attunement). You must be wearing the Belt of Herakles to attune to this weapon. The attunement ends if you take the belt off. While you are holding this weapon and attuned to it your strength score increases by 4 and can exceed 20 but not 30. When you critically strike on an attack roll with this weapon each creature of your choice within 30 feet must succeed on a DC 17 Strength saving throw or be pushed 10 feet away and be knocked prone.

Once per day, while you are attuned to it, you may make a ranged attack with the hammer, hurling it as if it had the thrown property with a normal range of 40 feet and a long range of 80 feet. If the attack hits, the hammer unleashes a thunderclap and a flash of light that is audible and visible out to 300 feet. The target and every creature within 30 feet of it must succeed on a DC 17 Constitution saving throw or take 5d6 thunder damage, aswell as take 5d6 fire damage and be knocked prone. A creature that succeeds on its saving throw takes half as much damage and is not knocked prone. After this attack, the hammer returns to its wielder.

Siege Monster (requires attunement). While attuned to a Meteor hammer you deal double damage to objects and structures.
