i keep missing the cocatrice how i do hit him more
If you have trouble hitting something, it's usually a sign that you're either not high enough level or you're using the wrong sword style. Remember in the tutorial, where you learned Strong style, Fast style, and Group style? Those differences are crucial. Obviously, you don't want Group style for a single cocatrice.
For other monsters, it's best to use Strong style if you can hit them with it (it does lots more damage) and Fast style if you can't. What level are you?What style are you using on the cocatrice? If you're using Strong style, change to Fast -- it should make a big difference.
