@ Omar: "Something like that; I can produce sounds in an specific frequency so that both sounds- the one produced by me and the one produced by the defense drones sensors - would interfere negatively with each other and cancel their signals. But you know how precise this should be? And how tiresome? I can try, really, but I would need to go by trial and error to match the specific sound needed, and even though I would not be completely sure if that's working."
It was somewhat impossible, but still worth a try; and it was not like Fractal was doing something else, after all - just throwing rocks from time to time.
So he experimented modulating his own voice signal to negate the drone signal, without much hope of success (but if he do... well, then his teammates would need to cope being with a really braggart elf with too much self-esteem).
