MIA: Missing in Action
B: (Blue Pill)

Early game you will want to harass with Q as much as you can without dying. At level 2, W will help a lot with surviving considering the extra lifesteal. Remember that you are able to stun with your E once you get it. You have to have lower health though! Watch for MIA's you are really squishy. Try not to B at all.

By now you will have your ulti, you're going to want to farm with it as much as you can. If you ever see an available lane with nobody there. Goto it, you will want to farm as much as you can so you can get to 18 before most people. In games you should be able to hit 18 when they are 14. It will mostly be farming the whole game till you hit 18.

By now, I don't really need to tell you what to do. You'll be unstoppable. Grab blue as much as you can, you want your ulti to be available a lot. Skill order - R Q W E and if they are running away, Q again. Don't be afraid of teamfights, your lifesteal is high enough that if you hit all of them at once with your ulti, your health will be like completely back.

Thanks for reading! :D
