1. Summoner spells: Yes, cat form is nice, but your choices, along with your interesting choice to not get boots at lv 1, leave you completely vulnerable before lv 6, and even once you have it, pounce can only do so much.

2. Runes: Your mix is completely off. The armor pen is fine, but the seals should be armor or health, and the quints should not be MS. You are fast enough to afford offensive quints.

3. Items: These are completely off. Boots at lv 1 are a must. After that, what you have suggested is just a mess. Your items give a nifty total of 50% not even counting your runes, while the max is 40%, meaning you are wasting gold on totally worthless CDR. A better alternative is to go straight for the Rageblade and then int the Trinity Force. This gives a much better mix of early and mid game damage, without wasting gold on excess CDR.

4. Skills: You clearly do not understand how Nidalee works. Her cat form ONLY benefits from the level of her ultimate, therefore taking extra levels in W is totally pointless. You should max Q first, E second, and take a level in W early but max it last. As always, take R at levels 6, 11, and 16.

5. Masteries: No. Just... no. 21/9/0 or 21/0/9 is acceptable, however. Putting points into the support tree can help your early mana problems, while the defense tree will keep you alive. Never go 30/0/0, even if she benefits from both the stats.

Summary: I have played a hell of a lot of Nidalee, both AD and AP. Please try what I have recommended before discounting me as a biased hater, as it appears you still need to learn how to play a good Nidalee.

Ewww clarity.

i picked the summer spells because I dont require flash or ghost to make an escape you are nidalee and perfectly capeable of pouncing out of trouble.. as for the trap you want to level it properly to benifit your cat form pounce because that little boost in the pounce could be what scores you a kill when an enemy flees.

Sorry about the lack of colors I will update it if the build itself works well with others... I want it to be ranked on its workability not it's eye candy.

I honestly hate your summoner spells (they dont give you any flanking possibilities), you dont use any colors or highlights making it hard to focus in the build, the skill sequence is a bit weird (why would you like to level up your trap?) and the runes....

I have tried this build 10 times and have been successful a lot in games ... I don't get an OP score much but it is a well rounded NID rather then just strong at one thing.
