I managed to finish this after multiple tries the first time but just barely. In later tries, even after hours of trying, nada. Yes, I used the armor that works (defense/offense/mana) at this stage, saved the number two for lightning towers (large island) and some nest/ballista concentrations, and destroyed as fast as number one cools down. Not as frustrating as, say, the General Raze battle (I just avoid it now) probably because I am destroying so much so fast with little threat to myself. The red zeppelin (hopefully not the led zeppelin

) is hardly damaged 2/3 of the way but as soon as the "last run" starts, it goes down in seconds. I doubt if there is much advise other then the vast number of write ups on this battle have already said but, if so, please don't hesitate to let it out!
Now, my question: I have tried lowering to "casual" for this battle but, I don't really notice a difference. Is there any?
