Hmm, so catapult launches an unworn object, and either flings it away or hits something to do damage to both the target and the object. So theoretically they could either throw the mace away, or potentially both do damage and destroy the mace at the same time.<br/><br/>Would we go with the book's idea of a small object having roughly 10hp? objects (https://roll20.net/compendium/dnd5e/Objects#content)
