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.
try this build. it makes everything melt when u spin real fast :)
if there are many casters : try mercuries instead of ninja tabi, and banshees veil before infinity edge
another good item to get if you can spare the gold late game is trinity force
stick to hitting minions.. you can shrug off a lot of dmg from the start, and after you get sunfires its awesome. judgement from brush like is never expected :P
your passive can help you lane too. your judgment is by for your most devastating spell, but try to spam all.
dont forget that decisive strike can really hurt towers too. this works when they are tower hugging: put on your courage, dec.strike turret and retreat. do this only when u know they wont snare or stun you at the tower, and with a teammate there and a lot of hp.
late game you can be destructive too, but you will be a bit more vulnerable so go with your team and blend(judgement) away!
