Need help with devil may cry

[MJGunn]

How do I beat this stupid scorpion thing? Help!

Are you talking about Nightmare, the spider? If yes, you need to hit his behind. Just go behind him and slash with the Alastor until he dies but don't stop running because his attacks can be deadly.

behind? the only time I only seem to do any damage is when I hit his face. am I missing something?
