With the release command of "challenge", one would expect something more threatening in appearance than Polilla's Resurreccion; this, like so many other things about your blade, is a deception. Upon release, cracks form on your mask and your blade and spread across your body, leaking a harsh radiance. The cracks spread until they cover your form, the light flaring bright enough to blind those who look at you at the moment of transformation, bursting from your shell with a sickening sound. As this last flash of light fades away and dies, the empty shell that was once your body hangs like a puppet where you stood. Black dust seeps out from the cracks in the now-brittle carapace, consuming it until the only feature left uncovered is your bone-white mask, its eyes dark pits. When you move, you leave a trail of black motes behind you. You like to pretend they form wings, like a moth. In this form you weigh nearly nothing, a creature of dust and shadow in a hollow shell, and your spells take on a dark cast.
Your Sonido changes as well, even the puppet losing its mass when you move. You turn immaterial and untouchable, passing through obstacles and opponents with no regard for their strength or speed. This does not mean you cannot touch others, however, for Polilla can strike those you pass through should you will it.
Further, your distance from the physical body you inhabit means wounds and even limb loss do not slow you, and given a moment's calm and a shadow to hide in, any damage may be repaired with unnatural speed, though this is tiring. Opponents must pin you down and deny you your shadows to truly threaten your life.
