Miss Fortune is one of the strongest marksman champions in League of Legends. She's weak in terms of mobility but deals extremely high damage. There was a time when the ability power item build was very popular, and I remember playing her a lot as a support during that period.

As far as I can tell, you're downloading the game replay from the match history. Can't you record it directly while playing? Or at least, I know there's a tab where the statistics are displayed. This way, we can't see how many kills you got 😂
