So, I'm wondering if there is a way to set an ambush such that a skeleton raises from the ground? Is there a prefab for this?
Or maybe any other creature raises from the ground?

Thanks!

Could you countersink the opening draug tomb ambush into the floor?

Actually, that's a cool idea ... Might solve a problem I'm having ... I'll give it a go this evening

There's also a "Nocturnal rise" animation somewhere
