When fighting the Dynalyfos Duo in the City in the Sky, don’t keep attacking them since they will block all your attacks and hit you with their own. Use your Ball and Chain to stun them and get in a few attacks. Repeat this until they are defeated. You can also combine your bow and arrow with the Hawkeye to make them fly back against the wall. Note: Bring at least 60 arrows since they don’t do much damage and you will most likely run out before they’re dead.
