I seem to remember the shapechanging helmet from one of the other games. Was it a thing in D:OS2?
That's what I've heard but I haven't played either Divinity game so I have no frame of reference. It reminds me of what the villain from Chronicles of Riddick's helmet looks like.
Oh yeah, I found it - it's the mask thing that the Skeleton character can make: https://divinity.fandom.com/wiki/Fane%27s_Mask_of_the_Shapeshifter
