Tactics against Necromancers.

Humans have a significant disadvantage – the speed of their troops (except for archers). This means that if there isn't a general slowdown, archers will move first, and then the undead will follow (including dragons, smart knights, and vampires). Therefore, it's not worth rushing into a decisive battle. However, the Tower and Conflux have an advantage: vampires don't resurrect from them. So, when playing against the undead, you need to take this into account as well.
