The current height of Blood River Commander Nirwinke is still five meters. With such a towering stature, using the "Annihilation Mirror Wheel" to attack any Aegean native can be described as overlooking them completely, with no theoretical attack blind spots at all — the earlier performance of Ruicadonya has fully demonstrated this point. Even if there are burly warriors standing in front for cover, the relatively short stature of the Aegean natives still makes it impossible for them to avoid the top-down carpet-style strike of the "Light of Annihilation".
The "Annihilation Mirror Wheel" has been used once currently, and there are still two opportunities to use it before it cools down.
