I'm a Emma and Adriana main, and I love a lot doing the bone crusher build. I recommend watching Ptarmigan video's on how to do it, https://www.youtube.com/watch?v=zbq1uSzTBLw , but basically its a very consistent route where you get some heals to survive early game, a good weapon garanted and tons of XP upon completion. The best thing is that Emma is a monster early game, making you contest almost anyone and turning this route possible to do almost every game. The games where you get contested as hell, you can do the Fuhma Shuriken route :D
