Mod question altering weapons

[Ragnarok-X]

Is there a way to create a spell which alters or enhances the weapons of a target ? Something like giving the buffed unit deathbless weapons or making the weapons armorpenetrating or negating ?

I dont think there is a stock spell that does it (which i could copyspell) is there ?
