Demgorgon pink addon suggestion
As it is, i feel like the pallet breaking red addon for demogorgon doesn't do much. Instead I would like to suggest a more thematically appropriate addon.
The addon would passively drain gen progress within his terror radius. Not as if he kicked them, so it doesn't trigger surveilence, it just passively drains gen progress and then stops when he leaves the area.
