Tactics for Rampart.

Well, I think that when it comes to neutral creatures in the first week, playing as Tower and using magic is a good strategy :D - especially if you get lucky with the Slow spell... ;) And just shooting them down with Magic Bolt... Wizards have a lot of mana, which is also a plus!
P.S. But in general (returning to the topic) - in Fortress, I don't like Drendroids and Gnomes - simply because they are slow, and their movement on the map is terrible... and without them, battles are difficult... It's a double-edged sword!
