Benji, how I got it, when you start, put four troops on S. Europe, one on Scandinavia or N. Europe, take S. Europe to Middle East, next turn, four on Middle East, one again on whichever you put it the first time, then Middle East to India, repeat with the one, then get Ukraine the next turn, conquer Siam, and then you should have the ten troop bonus.
Love the concept! I think it needs work for the webs and eating things, it's hard to keep up with all the damage once you get a solid one and keeping your stats up. Might just be me though. xD
While this is absolutely more fun than any other GemCraft so far, I'm immensely pissed off that the only one where endurance would be fun, you have to pay for it. :/
