I wanted to make a build on Nasus because I play him a lot. I wanted to show a different way of how to play nasus, CDR nasus. I hope you like my build.

I choose Greater Mark of so you can get though armor easier. You can switch them with AD flats or per level if you want. I choose armor and Magic resist so you can survive the early game and farm up. You will take less damage from mages and AD. I also chose some CDR because even with frozen I also choose AD quints so you can still have some damage even though you are tanky.

I go 0/21/9. I go for utility for the mana early game. You won't have mana issues early game but if you are spamming your e and w, you are going to be oom. I go for defend for some hp and cdr and some defence.

I choose Siphoning first for easier q farming. It is also your damage and lowers the cdr on q faster. You can choose your Wither, or the E. I suggest that you take e first if they are building armor. I chose wither when they have 3 and more ad champs. I choose E if there isn't a lot of ad or for the armor pen.

Teleport Good for staying in lane, dragon fights, help with lanes and ganking.

Flash is for escaping and catching up. With exhaust and flash up, you will usually escape a one vs one or catch up from people running away.

Pros: With the runes not able to deny easily.
Able to stay long in a fight.
Tanky. A lot of armor and a decent amount of MR. Able to destroy there team with a q farm. Can come back in a game and win.
Able to stay in lane for a long time with passive.

Cons: Can be kited when exhaust and w are off cd.
Can be denied from ganks, or just counter picks.

During the laning phase, you usually want solo top. You should focus on farming your q, but shouldn't go to harass enemy champs if you are going to miss some farm. You want to farm farm farm to get the cdr then farm more.
NOTE: IF you are having trouble wait till a little later in the game or ask for a gank.

Ghost Good spell, can switch with flash.

Exhaust Good for chasing, shutting down ad, slowing.

Cleanse Can get rid of other summoner spells, and is good for escaping.

Heal Got a lot better with the new spells.
I honestly think other spells on nasus aren't that good.

If you already have a tank, and really don't want Cooldowns but you want attack damage then.

I spell the philo stone later in the game so I can get other items. I get Philo Stone so I can get the Gold Per 5 and health regen and mana regen.

Can be switched with

For tanky champs like you can get or

THE END
