Behavior LifetimeUpdate LifetimeTag WaitForWakeUp = Yes End
This time, it's code that I've seen many times, but I've never really known its purpose. Maybe somebody, (Deezire?) knows how it works?
Judging by the fact that only Mumakil, Trolls, and Boromir have it. I'm assuming it has something to do with the "Rampage" ability?
...I removed it from the Mountain Troll once, a long time ago, to see what would happen. IIRC the troll just died on creation.
