"Uh, if I took enough magical damage, or if somebody got into my systems and dismantled me, and I guess there's probably an amount of physical damage that would take me out but it'd be a lot. And I know some Devices have design flaws or unstable modules that mean they damage themselves when they cast spells close to their power limit, but lucky me, I'm good on that front. So basically there is nothing in this universe that can kill me, unless it's some of your weird magic."
