Does anyone know what it is that causes Invisibility to be dispelled when you attack, open a door, open a chest etc?

I'd like to make an Invisibility True, or Improved Invisibility MGEF, like in Daggerfall, where you remain invisible for the full duration, no matter what you do.

Is this possible?

Cheers!

It's the hardcoded Invisibility archetype, and many others had tried to find ways to bypass it and recreate the perma-effect from Oblivion.

Better to Manipulate Chameleon, as that effect does not go away by design.

Of course, you need this mod to start with
