I'm currently playing a 13th level magus who has craft arms and armor as a feat. If I want to add spell storing to my rapier, can I do that for free? I meet the prerequisites (craft magic arms and armor; at least a 12th level caster), but it seems odd not to pay. Of course, I can't pay myself. And it seems from the requirements below that I can add the enhancement. Or does "special creator" signify something? Any advice will be welcome!

DESCRIPTION
A spell storing weapon allows a spellcaster to store a single targeted spell of up to 3rd level in the weapon. (The spell must have a casting time of 1 standard action.) Anytime the weapon strikes a creature and the creature takes damage from it, the weapon can immediately cast the spell on that creature as a free action if the wielder desires. (This special ability is an exception to the general rule that casting a spell from an item takes at least as long as casting that spell normally.) Once the spell has been cast from the weapon, a spellcaster can cast any other targeted spell of up to 3rd level into it. The weapon magically imparts to the wielder the name of the spell currently stored within it. A randomly rolled spell storing weapon has a 50% chance of having a spell stored in it already. This special ability can only be placed on melee weapons.
A spell storing weapon emits a strong aura of the evocation school, plus the aura of the spell currently stored.
