This titanic hammer resembles a darkened globe of impenetrable black iron. When you hit with an attack made with this magic hammer, it deals 2d12 bludgeoning damage, instead of 2d6. This weapon deals double damage to objects and structures.

In addition, you can use an action to cast the "earthquake" spell from the hammer (save DC 17), slamming the weapon into the ground as part of the action to cast it. You and up to ten other creatures of your choice that you can see automatically succeed on the saving throw against being knocked prone by the spell. This version of the spell extends from you in a 100-foot radius and doesn’t require concentration, but ends at the end of your next turn. Once this property of the hammer has been used, it can’t be used again until a number of days have passed equal to half the number of fissures created by the spell (minimum of 1 day).

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

Notes: Replace Damage Type: Slashing, creature with Strength score of 17 or higher, Heavy, Two-Handed, Topple
