Here are one more ruling from last session:
Very Fine, Meteoric Weapons
I allow Very Fine and Meteoric on the same weapon in DF. What the heck.
Magebane is a Very Fine Meteoric sword.
One of the PCs just ordered a Very Fine Meteoric knife.
I let him do it, of course.
But it's just odd. It's clearly iron, not steel, because it says so, which makes sen. But Very Fine craftsmanship means the weapon is as good as the best possible steel . . . but it's iron, which we know makes inferior weapons to steel. It can't be alloyed, because then it's not purely magic-dead metal.
Still, it's DF, and exceptionally well-made weapons of non-standard materials should just be a thing. So therefore, it is.
