I'm pretty sure this Mace and Mace of Disruption have their names incorrectly swapped based on what they do.
Agreed, I got really confused when I saw that a mace of smiting was especially effective against constructs. But it's the same in the book, so I don't know.
In 2nd edition it was called rod of smiting and it was also for smiting constructs and outsiders. Also in 2nd edition the mace of disruption was meant to disrupt undead.
Yeah, I found this comment explaining it on reddit:
As someone who began playing in 1978 when D&D came as a three book boxed set, I can tell you the major difference.
First the Rod of Smiting and the Mace of Disruption are from the early days of AD&D as you already noted, but they were much different then. The mace of disruption disrupts the negative energy that powers all undead. The Rod of Smiting was more about striking power and affected constructs as well as everything else. At the time constructs were notoriously difficult because of Magic Resistance rules back in the early ad&d days. Constructs could only be beaten by adamantine or lots and lots of physical damage. Smiting added that physical damage. It was holy damage then and the magic resistance did not stop holy damage. thus smiting became the weapon of choice for constructs. As the editions of d&d have advanced they have mutated slightly but maintained that disruption is the disruption of negative energy, which means it also affects extraplanar creatures like demons and devils, and Smiting is the holy side of increased physical damage, but it also works on evil creatures just fine.
always felt that way too.
No. It is not. In previous editions Disruption always were against undead. And Smiting against constructs.
Does the auto destroy only occur if you critted the construct?
Yes. Only if you roll a natural 20 on the attack
Maybe, but the word Smite simply means to deliver a firm blow, if it was the Divine mace of smiting they 100%, but when you think about it the mace dose exactly what the name says if you roll well enough against a construct you hit it with a firm blow.
