Any idea how to make a target temporarily invulnerable to all damage including havoc? Obviously there is the function SetInvulnerable() but it is cast on an actorbase and not an actor. I have used the function GetActorBase and then set the invulnerable flag, it seemingly works fine on named actors however doesn't appear to apply on generic leveled actors.

Any ideas? I am open to any type of hack or workaround, and might even settle for something that eliminated only 90% of damage. Thanks!

I've used http://www.creationkit.com/SetGhost_-_Actor before to make it so the player couldn't harm an actor in any way. Note: At least in Fallout, it would also disable their collisions with weapons. Meaning bullets, rockets, etc (I presume Arrows in Skyrim) go right through them. However, they also can't be harmed, and it's called on a single actor.

I'll give that a shot, I'm curious if it affects falling damage as well. Thanks!

There is a perk that uses mod incoming damage or something like that, set it to 0 I think.
