Q:I am having trouble beating a stage, can anyone help?
A:Yes of course. First thing is if you got units that your gonna use for that level and if thier Level is not Maxed, max it out. Go back to some easy stages and train them until they reach Maximum Level, this will help alot because your units will stronger! Second of all is if you just used shield on money and castle upgrades and not unit upgrades, I'd say balance the system out! Get some unit, spell, and Castle upgrades, but not too much of any! Finally... look back to the past stages you beat... Did you get all the shields? If you did not go back and get them! Use them for upgrades,spell, or to unlock more units, because having more shields = More powerful force!
