Do Weapons of Pure Magic scale with SM? (Pyramid #3/60)

[PseudoFenton]

The Mystic Power-Ups article in Pyramid #3/60 - Dungeon Fantasy III adds in the option for Weapons of Pure Magic, which allow you to conjure magical equivalent weapons to use (at a cost).

The damage values and descriptions of these are clearly tailored to an SM 0 adventurer, so what happens when a Gnome or a Ogre summons one? A greatsword that is "as long as you are tall, and a hand-span wide" would look very different depending on who summoned it - but the statistics currently remain the same.

Should larger SM races pay more to get higher (and more appropriate to their size) damage? Whilst smaller SM races get a discount but have to shunt the damage down?
Do they automatically scale to equivalent size, but remain the same cost (the natural benefit, or drawback, from being bigger or smaller)?
Or do they always do the same damage regardless of size, and Pixie Mystic Knights are now the best thing since sliced bread - which incidentally can be dwarven bread and still be sliced with a lazy swing of their 5 inch long greatsword. (Okay, Pixies will still struggle ST wise for other sources of damage, but some weapons really do give them a huge leg up - so this is more of an edge case which highlights the oddities).

So, what're you thoughts? (I'll be PMing the author, Antoni Ten Monrós so he can weigh in himself, btw).
