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.
I personally like attack damage more than ability power because late game ability power is not that great.When it was my first game with Nidalee i tried this build. I got a really good score.Now Nidalee is my favorite.
Boots of Swiftness for catching up to people.
Starks for the attack speed and lifesteal.
Last Whisper for the pen and it has attack dmg and attack speed.
Gunblade because it gives you AP and AD
Wits End for the extra attack speed.
Black Cleaver for all the dmg it gives and the pen.
