That makes no sense. WHY would it have AM properties but clocak signatures as well? Cloaking signatures doesn't help AM in any way. And AM doesn't help cloaking signatures in any way. The effects need to make sense and work with one another. Not just putting every effect in the book on one piece of tech or material just so you can solve all your problems... I'm sorry, minerals don't work like that. You can't just take a magic rock and say it does "this, this, this, this, this, and this! THERE I'M SAFE NOW." You can give it one set of effects that work one way, or a different way. But not contradicting ones.
