Appearing as a simple mace with a large featureless sphere for a head, a mace forged as a Wrecking Ball favors simple, blunt, and direct methods of dealing with obstacles.  You have a +1 bonus to attack and damage rolls made with this magic weapon.

 

Upon striking any inanimate man-made fortification or structure with this mace, and only when striking those objects, more properties of this magic weapon come into effect:

• If the fortification or structure has hit points, this mace deals triple damage.  Otherwise, fortifications and structures simply count as being weaker, at your DM's discretion.
• The wielder counts as one size larger and having a strength attribute of 20.  If the wielder's strength was already above 20, use that value instead.
• The wielder has advantage on related strength checks.
• The wielder gets fatigued from the strikes at half the rate they normally would.

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