Northern Keep as a standalone tower is capable of fighting off one or two weak enemies, but won't last long in a thick fight.
The keep has a special ability that creates an aura around the tower, one that can Amplify Damage (red) or Reduce Incoming Damage (blue). This ability however is trapped behind a lengthy cooldown.
This tower is an excellent compliment to early/mid-game defenses where most of your units are Small and Medium, as the Aura will benefit them.
