Khaim said:Are you assuming the weapon adds to his damage? Because everything we've seen says it doesn't. The Magic Item article hinted that the "big three" are sort of meant to balance each other. You have a weapon (or implement) for attacks, armor for AC, and the neck slot for F/R/W. It all works out, as long as weapons don't increase damage. We know a magic weapon adds to crit damage. If it also adds to normal damage, that would be redundant.
The recent magic item article strongly suggests that it is +to hit/+to damage. However, most of the boost comes from the +hit.
As for DR (I assume FR is a typo), you'll note that as a level 26 demon he doesn't have any. Which is a very, very good clue that there isn't any in 4e at all. I'm pretty sure one of the designers said as much, anyways.
Against a foe with mere FR 5 (you are going up against a freaking fire devil, be prepared), his mace does a pathetic d12+6, with no ongoing effect. Now, if you were a highly intelligent, wise and presumably wealthy devil lord with a massive overload of fire based damage abilities, what weapon would you choose? Something that is *useless* against people ready for you, or something that ignores defenses against fire *and* does more damage even against people without fire protection to boot?
If you are wearing armor (is he? if not, why not?), wouldn't you invest in the very best? Same with the neck slot. But, given his equipment list, he appears to be virtually flat broke. He should sell his mace and buy something actually useful. But wait, that wouldn't be *thematic*, and it would imperil *the math*! If he actually is using the gear, why can't I steal it or dispel it during the fight, or loot it after? If is isn't, WHY OH WHY isn't he?!

(again, in 3e, without the math being a central selling point, this wasn't as important. And even then, lots of monsters were statted up with appropriate power-level armor and weapons)
