Use the Right Weapon:
Each of the six different weapons does different damage to different # opponents. If one type of projectile isn't working, try switching to another one.
Shoot Down Airships:
You don't have to destroy the hull of the airships to shoot them down.
Just pick off all the guys standing on the deck and down it goes!
Dragons Are Cool:
You can bounce fireballs off the top scaly part of your dragon. You can bounce ice off the bottom smooth part of your dragon.
Being a dragon is cool that way.
Fireballs will bounce off the top scaly part of your dragon. Ice will bounce off the bottom smooth part of your dragon.
