"Champions are anomalies on this world, all of sudden, normal humans become something else, however, among champions there is clear distinction, the normal champions and the elemental ones, the elementals are the champions that have… let's call it an extra, and that is our invulnerable form" Said Mirana.
"Invulnerable form?" Asked Io.
"That's right, the invulnerable form is a special way that let us become invulnerable to physical and soul attacks… at least for some time, of course, if we could use this ability infinitely, we wouldn't be afraid of even emperors and the such… we can use this ability only once, after that, we must paid a heavy penalty… and that price is to lose our powers as a champion" Said Mirana.
"Lo-lose your powers!?" Asked Io.
"Exactly, as for why, well, there is a good reason… the invulnerable form not only give us a practically immortal body for some time… it give us another plus…" Said mirana while taking a deep breath.
