Weapon-affecting spells

[Vynd]

Do spells like Weapons of Sharpness or Astral Weapon work on any sort of weapon or are there limits? For instance, can you Astral Weapon your firsts? Will Weapons of Sharpness make a dragon's breath weapon armor piercing? Can the weapon destroying spell (I forget its name) destroy your claws or sleep vines or what-have you?

I am pretty sure that astral weapon works on fists and "natural" weapons as well. I am still not sure as to weapons of sharpness on ranged attacks -- I think not, but am awaiting authoratative info in another thread (of mine) with a similar topic. I don't know of a weapon-destroying spell offhand -- do you mean the armor-destroying one?
