loving this game!
took a while but finally beat all the levels. awesome artwork, great for thought invoking, however, there is 1 downside i found, that really got to me. when facing the little goblin rangers, once in a while they will slip past your leading blockers and make their way back to your hero. before you know it, you have to replay the entire level.
a few tips if you are having trouble later in the game.
1. spam shield, for 25 mana, extend the life of your heavy blockers.
2. lv1 meteor will nearly kill the golems on the last normal mission. this spell (along with tornado) is great for knockback, giving you more room to play with.
3. building healing towers is great when facing a tough boss, as you move through the ranks, you build up, as you fall back from being attacked by the boss, you can still be healing. (this works great with the giant golem, but really bad with the undead wolf)
4. ranged + lighting (the amazon works REALLY well) this will stun the smaller targets. the amazon's attack goes through all targets, till it hits the ground. thus, you could hit 4-5 units in one shot, stunning them in the process. also, with 1 accessory, it helps all the units in that group, so all the amazon's get the lighting attack.
5. the giant golem is TOUGH, with a ton of HP, however, (thanks to danyalejandro for pointing this out) spam a lot of little units (goblins, the flyer gun guys, ect) to slow down the golem, let your spells and ranged units do the fighting.
as always, these are just a few ideas, and might not work for everyone as well as they did for me. have fun with the game, and i am looking forward to more great epic war games!
