heres some tips for the "impossible"
its simple to beat the end! alls you really need to do is max out your crossbow for sure. that should be your main priority in the game it helps out soo much! secondly. when your in the last level you need to get your mana up to max it is a must! thirdly spam smaller units. its simple. if your sending out hundreds of hobbits the end will attack them and slow its trek to your castle. then send out as many big units as you can as well such as your angel and dragon. do this and i can guarentee a sure fire win! if you have any questions feel free to add me and message me. ive beaten this game plenty of times to know how to win. ive also beaten every epic war game there is so any questions on the series ask away and good luck to everyone!
