Not irrelevant at all and your refusal to respond is very telling. Particularly, this statement of yours: tells me that you don't think it's possible for a 9th-level spell to be broken. How can we even have a reasonable discussion on the brokenness of a spell when you don't even agree that such is possible?
I think you may have musunderstood me.
If MD, for example, had no down side to the caster and no save as well as SR not applying, I think we'd all agree that would be broken.
As is, there is no way to
definitively measure its power level as it has no standarized numerical effect.
But, given that one's items can be sundered and taken with disarm, I do not see a spell with "save-or-die" type of effect for each item to really be unbalancing, especially with the built-in disincentive to cast it of the very real chance of losing all spell casting abilities as well as destroying the treasure you would get from the battle.
In general, I would view MD as being used only when critical to the plot. Among other things, you can never tell what it will do to the party - perhaps nothing at all if all saves are made. Most likley, a few items will be destroyed. That's generally not such a big deal, though its true effect on the party is basically random.
If I were to house-rule this at all, I would add bonuses to the Will save based upon an item's power. Maybe something like caster level divided by four, rounding up (so that caster level 5 = +2 bonus on the save). I do not think it is needed, but it's pretty reasonable.
