With a deep breath, Eiro let this new sort of magic flow through his body. Well, it wasn't directly 'new', it was just foreign to him directly. The moment that this Death Magic flowed through him, he could feel his whole body slowly decay. As if he was rotting, or mummifying, rather. His horns and along his bones in his wings, layers of thick bones formed.
It was like his eyes slowly disappeared and he got dark rings around his eyes that just seemed as if his eyesockets were completely empty. His body temperature dropped considerably, and his heart-beat was close to unnoticeable. Certainly, this was a perfect way to pretend to be dead if he needed to do so at some point, but for now, it just felt quite horrifying.
For one, because this wasn't the sort of transformation that looked bad but was incredibly strong, his physical body really became incredibly weak. It was uncomfortable, and it felt as if his bones could break just by taking a few steps.
