This is my first build created. I haved used other nasus builds on here and decided to create my own. This focuses on nasus becoming a tank for the team. Also, it focuses on the damage of siphoning strike + sheen.

Pros - Tank,Heavy damage output early, Tank Ult, CR is good, Tower killer,
Cons - Early game is mana hungry and squishy, can't tower dive early

I put Armor Pens for siphoning strike to hit harder against any champ. If its rammus, or just a squishy, it helps with the damage output.
I use evasion seals for the dodge chance. This helps with the tanky aspect of it.
I put in the replenishment glyphs as Nasus is mana hungry early. This can keep you in the lane longer so you dont have to back and get mana or stay in the lane with no mana.
My quints are fortitude for the early HP boost plus the veteran scars. Veteran scars is getting nerfed in the upcoming patch so this are an obvious choice.

I like ghost and flash. they have savd me on more than 1 occasion when used together. I tower dived an akali and got the kill. I ghosted out and a chogath was waiting for me. He used his Rupture ability which wouldve given him the chance to attack and kill me. I flashed past him and ran to turret hump. This has happened numerous times and ive saved myself with this combo.

The 21 in defense is normal tank masteries in my opinion. The 9 in utility is for the mana regen early game. Also, in the double lane, the exp will come a bit quicker allowing you to level more. This also includes ghost improvement and bit less time dead seeming as your tank.

Sheen - Self explanatory with siphoning strike
Ionian boots - CR on siphoning strike letting you farm better with siphoning strike.
Omen - Armor for the tank. Health regen for more laning/farming. The gold helps too.
Force of nature - Outstanding health regen. Also, the magic resistance for the tank is pretty much what its used for.
Sunfire - Armor + health = awesome tanking item. The damage in the team fights helps out a lot too.
Veil - The magic resist is good. The spell block also helps if there is a gank and they try to snare you.


Additional items - A spirit Visage is good. The + on the regens and the CR is great for more farming and tower killing . You could get a guardian angel and other items depending on the other team such as AP casters or heavy DPS.

Since you'll be in the 2v2 lane, you can help mid if the enemy champ is pushing. I like to ghost up there and hit him with wither. I then lay down a spirit fire where he is running (if he is running) making him eat it. I ult at some point when this happens for the health and continuous dmage to him. Also, i use siphoning strike as much as i can so pound him with it + the sheen boost. He should start running at which point i would tower dive for the kill.

You always initiate the fight! You take your teams damage so your squishies own the other team with you. Also, YOU TAKE THE DAMAGE FROM THE BARON! Baron is essential for the win. You take the dmage while your team kills it. The buff plus a trinity force (if you have it)will make you unstoppable. You, in team fights, can now annihilate enemies like no other.
