this guide is a work in progress. I forgot to change my runes and took my ezreal kleptomancy runes into a game as nocturne and ended up doing really well and we won the game even though it was 4v5 so I decided to see if I could actually make it work. feel free to leave comments and feedback and try it yourself.
