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.
the build you see, is the final one, in a really bad order, so, here goes the proper order:
start off with a long sword and a healing potion, go lane until you got around 2000gold. Recall and buy Madreds Razers and a recurve bow. Go back to your lane until you can afford Madreds Bloodrazors and tier 1 boots. Then go farm money till you can afford phage + sheen. After that you buy Banshees Veil to get some survivabilty. After that complete Trinity Force. Finish off your boots into Mercury Treads and buy phantom dancer / bloodthirster depending on the case. If you're having a great flow, go for phantom dancer, if you some life stealing to stay alive, buy The Bloodthirster. After this you should be approxmately impossible to kill, do vicious damage, and pwn the **** outta all of your opponents. Don't initiate as Nidalee and dont stay in Cougar the whole fight, take advantage of that your spell doesnt cost any mana in cougar so you can literally heal and keep traps up and throw javelins as soon as they're ready. Hope this helped alot and wud be fun it this guide goes effective for all you Nidalee lovers.
