Nightmare hadn't expected the spike to penetrate the dragons' flesh, few physical objects could. No, As the piece of building that was hefted at her exploded, his spike wove through he debris and loops around her neck. He leaps from the roof he is on, the chain pulling him towards the dragon at great speed. His smoke sword at the ready, Nightmare had to hope the dragon wasn't particularity magic resistant. Then his blade may be able to at least wound the creature, as shallow as the wound would be on the large dragon. If that was the case, Nightmare was happy to fight a battle of a thousand cuts. He couldn't bleed after all.
