kill him and dont get burned

**** on his head

hide behind a piller he wont come so the after the breaths fire hit him with bow

The Cyodrake is slow and not to mention, he stops very often to use his breath attack...
The breath attack is strong since it can burn you up and damage you continuously...
Observe distance...
When you're far enough from him, use long-ranged weapons...
You may hold the attack button for faster attacks...
And that should do the trick...
