Inessa's ice sprouts first followed by Ander's cage, crawling over the child's ankles and legs, holding him in place. He growls and tries to flare out his flames, attempting to melt it, but that makes him distracted enough for Ciri to plunge her knife into his right eye.

The child screams, clearly not expecting that level of pain, and the pain makes him wilder than ever. He lunges blindly for Ciri, intent on exacting his revenge--

Then Heiran's sword comes down.

It does go through to his neck - but only about partway before the crystallization of his blood happens again and that, too, wraps around Herian's blade, keeping it there. The same happens with his eye as well, making it all a far more gruesome sight than ever. The child roars now, his anger and pain further fueling the demonic fires that burn within, and the lyrium around his injuries catch fire, melting the ice, before he lunges out to try and strike his closest opponent once more. The injuries mean he isn't as fast as before, and losing one eye means his aim is going to be rather off, but the child clearly doesn't care. All he wants to do is to burn and to hurt.
