Firstly; this build is not yet complete, I will be adding to it daily.

This build will allow you to effectively carry uphold your team in a lane push forever due to nidalee's stupidly large heal; and allow stupidly annoying spear poking on the run up to team fights and throughout game after getting your first needlessly overpowered rod.

For marks I take Magic penetration for huge spear damage throughout the early + late game. (Gets rid almost completely of that annoying base magic resist).
For seals I take Armour Nidalee is incredibly squishy throughout the game; and that extra armour makes running away from teamfights and early failed ganks that extra bit easier.
For Glyphs I take cooldown reduction; This doesn't seem like a lot; but being able to throw an extra spear every so often, pop an extra heal when the cooldown wouldn't have been up to save an ally, or hop away with your W that little bit more; You'll be glad you got them.
For Quintessences I take Mana Regen; More bushwacks, More spears, More heals, Longer lane presence; Huge advantage over opponents.

Taking the 9 points in offence is way worth it for the extra 15% magic penetration; will make those spears hit alittle bit more; the more the merrier! In addittion to this taking the 21 points in utility will provide nice cooldown reductions and you'll need the faster movement speed, experience gain and mana regen all the same.

You could take one point in the flash mastery if you fear for the epic cooldown, but you don't need it, you wont notice the effect over something else that you could have like that 1% extra mana or the neutral monster buff increase.

Early in game ensure that you take bushwack as your first skill point; with the meki pendant you will easily be able to place an infinite amount of bushwacks at level one and you should make certain that you do this; as it will make controlling the lane alot easier providing bursts of vision and annoying little sparks of damage, putting your opponents on edge throughout the first 5 minutes; Your next spell could be either the spear or the heal; It all depends on who you're laning with; and how the opening engagement with your opponents went.

1) If you are in lane with a strong AD carry such as Caitlin taking heal first would provide you with a fantastic advantage; the additional attack speed would make them a force to be recconed with and they would have a nice heal to fall back on after each little push. If you take heal first try to prioritise using the heal for attack speed instead of actually keeping you alive; Don't rely on falling back and healing yourself to half health to survive.. because this won't happen!
2) If you are in lane the opening engagement went very well for you and you are against an incredibly squishy character such as ashe you may consider taking the spear; be sure that you try to avoid doing this wherever possible; since it's damage output will be pityfull untill about level 7 where you get it's second level; and maybe even a needlessly large; DON'T SPAM THE SPEARS UNTILL YOU HAVE THE ROD(Edit: Unless you know that you could get a kill from it)
