So, taking on the idea as far as the chip being used, if it is going to be firing off anything, I need it to have a side effect when being in close proximity to magic. Burning heat, or a bright light, or something. The Scar itself is just a collection of constantly firing untamed magic, so an item detecting it would need to give off something in response. 

And thanks for going to the one grenade, because that is again a hell of a set of equipment, metal mage or no. Good on you to get involved in the fight!
