You should warn people the passwords only give you gems instead of starting you off where you were before.
The orcs look like frogs to me so i only played their conquests.
Don't decimate the enemy as fast as you can let 1 or 2 of them slip by every 4 of your units that get through. honor points are only won in death so drag the battle out as long as you can.
You can pretty much beat it with only defense up, regen, and mana asorption.
