Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
This build is for those who don't want to get up close with w,e instead with w,q. High output damage, really good for harassing and counter ganks. With the runes and masteries you should be putting out 137 dmg with level 1 Overload from the beginning and it has a low cd so its very spammable. End game, you are going to be able to take considerate damage, like other ryzes that doesn't mean you should stand in the middle of all fights, this is just that extra umph when your being targeted.
