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.
Boots of Lucidity instead of mobility
Cap instead of zhonya's ring.
Upgrade shatter to level 5 by level 9 then start jungling. At this time you should have boots and AAs. When you clear a jungle side then move into the lanes, heal your teammates and get a few kills with your stun. At level 15 get all 3 buff potions and rainbow it up for a couple easy kills.
Key to build:
If they are mostly autoers like tryndamere or sion then go thornmail if their mostly casters like Kass or ryze then go force of nature.
