I still think the way
Keroko and I view it makes more sense. The raw magic emitted from the Linker Cores by itself does not do anything. It has to be
transformed or refined so that mages can use them to cast spells.
This is how I see it: Every living thing has a Linker Core, no matter if you're a mage or not (this was said in A's). The Linker Core is like your heart: If the energy emitted by the LC stops flowing, you will die. It is like your life force. This explains why Nanoha was very weak after Shamal drained most of her LC. If the AMF disrupts the flow of this energy, any living thing inside the Field would start losing stamina, then its consciousness, and eventually it would die.
But the fact that you have a Linker Core and have magical aptitudes (like Nanoha before she met Yuuno) does not mean you can cast spells. This is where Intelligent Devices come in: to help mages use that raw magic, or if we use our theory's terms, to help mages transform that raw magic so it would be usable for casting spells.
With this in mind, and the fact that Erio's and Caro's health or stamina were not affected while inside the AMF, we came with the theory that the AMF does not disrupt the flow of raw magic (that which is emitted from LCs) but instead disrupts the
transformed raw magic used to cast spells. This is why we saw that Strada's enchantment was nullified, but nothing happened to Erio himself. This is why I believe that the AMF is actually a "Anti Magic-spell Field."
Also, what I tried to explain with use of
Hunter X Hunter terminology is that the AMF is but an enchantment, a Field-type magic defense (as explained in A's to Strikers Comics), not some hax. Caro proved this by using the "Enchanter field invalid" (the word "Enchanter" in the spells name should be enough clue
) enchantment on Erio's weapon to counter the AMF. In other words, the AMF has to have its limits, or it would be completely unstoppable.
I hope that makes sense.
