The enigmatic creature known as Nasus came to the League from a faraway world, and served as part of a vast and learned desert empire. There he was a respected and enlightened individual, having been made the Keeper of the Great Library. However, he was also part of a race of animalistic creatures that served as the rulers and protectors of the people. War was never more than a breath away, as others of his kind craved to enslave the people and claim totalitarian sovereignty. In the midst of a heated battle, just as Nasus was about to slay his treacherous brother Renekton, he was summoned to Runeterra. It didn't take much to convince him that Champions were needed to fight against the injustice here and he took up a place in the League of Legends. These days, he is the Keeper of the Sands, feeling most at home in the crumbling ruins of the Shurima Desert.

''The Keeper of the Sands, though contemplative, is not to be trifled with.''

Well first off nasus is a GREAT farmer and tank and DPS. He's one of the best well rounded characters in LoL. He's got the hp, the life steal, the dmg and atk speed. If u keep up on using your Q in late game u will be unstoppable.

PROS
Great Farmer
Very Strong throughout game
Few can take Nasus 1v1
Very versatile, (can be played tank or Dps)

CONS
Slow early game
Misuse of your Q spell could set u really behind
A little LvL dependent

let me add this, this item build is situaltional, for example u might buy FoN (Force of Nature) instead of thornmail, u might buy thornmail before impaler. but i cant stress this enough buy the first 6 items in order unless u want to change out the boots for something else. When it comes to it u will have doran sheild mercurys trends and 3 HoG (Heart of Gold) Sell the dorans sheild when u want to buy Frozen mallet. use ur free space for the next item then, sell 1 HoG for the next and so on, try to keep the HoG as long as u can the 15Gold Per 5 sec is what puts this build from the rest. **LAST item in build is situational can go with Guardian angel or my perferd Inf edge.**

I suggest u take the Recommended summoner spells on the fact of u have huge mana problems in the begining of game but I suposse u could replace heal with Exhaust or Ghost or Teleport.

In early game when u are in your lane dont over use spit fire. Try to use your Q, everytime the CoolDown is done kill a creep with your Q. I suggest you only use ur E while in a lane to kill the creeps close to your tower. Spit fire is an amazing way to farm but from what i've seen is hes like heimer if u push to far your going to get ganked. So the best suggestion i can give is use ur Q every cooldown and when u get pushed back to your tower let spit fire grab all that gold! Typicly i wont leave my lane untill i have about 2k gold so about lv 6-9 depending on how many kills u have. Grab your mercury trends and your first HoG!

Ok now that you have your boots and your first HoG start ganking! Nasus is an awesome ganker and initiator go jump some ppl with ur abilitys W-R-E-Q. chase them and continue to spam ur Q and W when ever they come up. but if ur team has even half a brain they will be dead before u need to use yuor slow again.You REALLY start to shine once u get lv 11. Your ult will destroy anyone in your way tanks.. dps.. EVERYONE.

Ok late game is a little simpler. Your main job in a team fight is to pop ur ult, use your W on the enemys DPS and life steal the **** out of everyone. At lvl 18 ur Q if done correctly should be putting out around 650-800 dmg. and your Q cooldown is pretty short and ur survivablity is pretty high.. u Will not Die if u know how to work the team fight!

This is my first build so constructive critisism is appreciated! If there is something im unclear on or if there needs to be some explaining LET ME KNOW! :) thanks for looking.
