Lucky for you, there are two tools to download almost any Rofl file of any game you want, even if you did not play that game. Imagine you did a Penta kill with Samira two days ago, but you forgot to download it on the client-side, and the game is not visible anymore on the match history tab because you played too many games, so what to do in this case?
How to download a ROFL file outside the client? The good news is that you can also play your Rofl files from ReplayBook by clicking on the blue button in the top right corner.
