I dont understand that mechanic sorry.
You move all your units under a waaagh tower. Check. You active it, you hear cool music and then we got firework and every cry waaagh.
But whats than?
What exactly do waagh?
How can i see how long the waaagh is active?
When i put 3 Waaagh Towers together and every of them waaagh does it stack and make the waaagh stronger?
