Ruiner Nergigante

Ruiner Nergigante also grows metallic spikes that do not regrow — break them to cut its lethality. Bone spikes harden into black armor if you leave them — break them before that. Once the head, wings, and forelegs harden, the divebomb is a cart if it connects. That dive also sheds the spikes, so the next cycle starts white again if the breaks were missed.
