lol easiest way to win, use undead and spam the mana re-gainers, then slow there advances with teh scout(upgrade asap) and if the scouts not strong enough use tank. i won first try =D
best team, warrior and cleric in front tanking and a mage and conjurer in the back. give the warrior life draining boosts, cleave, overwelm. your mage should have alot of poison and lifedrain for his thunderbolt to poison everyone and heal himself alot. use the cleric as a tank until she has to heal. and have the conjurer summon a war golem to the front to block and attack and a mana sprit to the back row to replenish you troops. ive lose about 2 fights with this team
