Nidalee is a huge damage dealer when you know how to play her . First of all, accdonring to me Nidalee is a middle lane hero because you can use spear in huge distance real easy. Also Nidalee is harder to play in a 2 vs. 2, of course that is just my thought. But you can easily dominate middle with Nidalee, especially I play easy against champions like Veigar and Ezreal because they cant use their skills easy with minions against them so you can harrass them with javelin toss easily.

For runes armor is kind of important because Nidalee is an often ganked champion. You need armor to survive the ganks also because Nidalee has heal has her skill aafter armor Nidalee is a dominating champion. Also you have to start with ability power so that you can damage the most with spear.

For masteries I take cooldown reduction and movement speed and ability power. Cooldown reduction is really important so I can heal more often. Low cooldown reduction on heal is really important against ignite. You can save yourself with a last minute heal. Of course you should trust thş so much and you should play a little defensive.

For items rabbadon and mercury treards are important because rabbadon gives huge ability power and mercury treads is a good item for magic resistance at the start of the game. Also you have armor for runes so at the start you start with almost %34 reduced magic and attack damage.

For summoner spells i take flash and ghost so I can escape and survive ganks easily. After lvl 6, its easier you should just transfrom into cougar and you can gett away easily with using flash ghost and second cougar ability.

Farming is real easy. Like I said I think Nidalee is best middle, so I go middle and i plant traps and the bushes. Usually a ganker comes in the middle of the bushes so they caught in my trap and their gank fails. You can jsut keep the enemies away by using javelin toss as a threat and you can farm real easy.
