Ultimately, the system Rorschach designed for Bart was purely reactive. A system modeled after the anti-missile defenses of his past life would require far more complex magic for target acquisition, aiming, and active countermeasures.
'It's not that magic couldn't do it, but you'd need a Tower Spirit at the very least, right? That's out of the question for Bart. If someone really had that level of technology plus a 'Magic Artificial Intelligence,' they might as well just build a Doomsday Mecha and have it camp out by the Mage Tower.'

The Alchemy Ink on the cup's base sizzled and evaporated, and the pieces laboriously pulled themselves back together.
