Sonic mace of returning (Neo)

sonic mace of returning:

A simple peasant's mace fortified with magic and enchanted to resonate the noise of its impact into the target.

Base damage is 5, but the damage bonus from the user is applied once more as sonic damage.

Not designed to be thrown, the mace flies back to the user's hand upon the last one to hold it saying "butter biscuits".
