Once you have enough points, about 25, take all of your points out of Barracks and stop using them. Instead, put everything into Reinforcements. They are durable at max level and are effective enough at slowing the enemy down that you dont need to waste space/money/points on barracks. You MUST build at least one Necromancer though, as they are necessary for generating enough troops to hold the enemy off while you attack them.
Max out Ranged and Reinforcements first. Put a few points in Mage and then max out Rain of Fire. It is incredibly effective at getting you out of tough situations and keeping you safe.
Consider spending the 10 kreds for Dierdra. Your heroes don't do a lot of damage, so buying offensive heroes is pointless. Dierdra is very effective at keeping troops alive and making towers stronger. Plus, her teleport ability allows her to cover the whole map easily
This is an awesome game. I love the grinding system and the Fame system. My only problem with it is that the Hunt tasks were repetitive and I lost interest in them after 15 or so. Once I got the hard badge I pretty much lost any interest in playing. But, it was really fun up until that point. So if you want to increase replayability, make Hunts more interesting! :D
really fun. For a sequel, I would love to see a "barracks" sort of upgrade. One that lets you upgrade your Allied Unit Spawner, and select which units you want it to spawn. Also, seperate weapon classes to choose from would be nice
