I saw a flaming eye in game weeks ago, shot it from afar. I have no mutations that seem like they’d cause anything, my negative ones are all minor and I have the armoured skin and very strong for positives.
Well it doesn’t show in my character menu, so I don’t know, not that I know of. My character isn’t sneezing or coughing.
Literally “your body is wracked with pain”, “your vision goes fuzzy”, etc.
