Not too difficult. RC the aerial guys, reflect if something is about to damage you.
Don't stop attacking for a second when it's down to the Lava/Ice things. It tends to get you hit.
For the 3 fat bandits, I just went Wisdom Form and spammed attacks. Saves the trouble of timing guard and reflect to handle two at a time.
