I've been trying to get the armored troll you can buy from the Dawnguard to be unkillable, since I don't like killable followers. Normally, I just set them to be essential in the console and that is that. However, I haven't been able to set the one that's spawned for the player essential even in the CK. Nor can I figure out its baseid beyond doubt, as I have no access to the source codew of the script that spawns it. I think that the main problem lies in that the spawned one is a subclass of, and therefore inherits the essential status of, a leveled creature, which can't be essential. Has anyone else tried doing this? Is there a way around this, whether through scipting or some trick in the CK? I mean, I guess I could try giving the damn thing 1 million helath, but that seems a rather inelegant solution.
