1. Best creature group is, 3 Trike in front, 3 Dragons in back, The Permanent upgrades just make it better. You can get both of these on the map just left of start. 2. Save OFTEN if you are religious about it you'll never have a problem with Exp loss. 3. Level up in start zone, it doesn't matter the enemies level, you always gain a level after a fight. Plus this up if you find it helpful.
