i focus primarily on maxing javelin, but according to the situation, feel free to adjust.

i cant tell you to strictly use this skill build, but the skill build from lvl 1 to lvl 6 should be essential (W on lvl 5 to get ready for pounce in cougar form)

Mana crystal 2 pots in the beginning, you can go amplifying tome, but the the ap boost doesnt really help in the beginning IMO

I previously used lich bane, and a lot of people use it probably because of its passive scaling off of AP (this is an AP nidalee build), but the trinity force is a better well-rounded item. Rushing for SHEEN is essential --> 8 skill rotations with nidalee. People often rush rageblade, but i go for sheen first.

If you're doing well in-game, just wait until u can buy trin force. If not, get a phage to help u with survivability.

I get sorcerers if there are only 1-2 carry champs in my team (including me) --> helps with the javelin
I get merc treads if the other team has a lot of CC or if my team is losing

Then get rageblade, with BLASTWAND first.

When building for Zhonya's hourglass, i usually get the armor first for survivablity, but it's up to you. I dont need to explain why i get hourglass before deathcap :)

Banshee just to finish it off! however, if it looks like ur team comp isnt that great, too much cc on other side, or ur losing, i would rush BV immediately after trin force.

flash-->ESSENTIAL to nidalee, because she jumps in and out of teamfights--> the flash is a good run away mechanism or it can even be used to chase an enemy

cleanse--> because it boosts my survivability--nidalee is a bit squishy even with armor.
