Lost Extremis Tony Fic
so I've been searching for this story for a couple of days now and I can't find it anymore.
Basically what I remember was that Tony lost his arm up to the middle of his forearm during CACW and was blinded in one eye. Extremis changed his eye to a vibrant blue and gave him extra powers. He also made a prosthetic arm with fake skin so no one would find out that he was that injured. Also he wears sunglasses everywhere. It also featured T'Challa and could have been IronStrange pairing but I don't really know about that.
That's about all I remember. I hope someone can help me with this.
