The prisms lodged in the bodies of Necroluff capture and refract light within their matrices. The structure of these crystals isn't fully understood, but they have been demonstrated to bear a remarkable similarity to that of Z-Crystals from Alola.
Necroluff keeps itself airborne by firing lasers at the ground, their colour depending on its mood. When it becomes upset, the beams shift toward violet and have often been mistaken for UFO lights.
