This guide is not completed at all. I will continue to work on it whenever I have time and feel like it. If you have any questions just ask away and I will get back to you. If you are looking for help with Diana as a champ you can also come and visit r/DianaMains. Just make sure to use the search function and the sidebar before asking basic stuff as most of it has been answered a lot of times before.

Quick disclaimer: The names associated with the build don't mean that they invented that build. It's just what each player usually runs. Also, nothing is set in stone here so change the builds and runes up however you want. My intention is to give you a good starting point and later telling you what options are useful in what situations.
