Hi! I'm SummoningDude, and I just recently picked up Nasus, and really enjoy playing him. He can be a very strong pick if you build him right, and if you stack properly. This is also the first guide I've made, so I would like the feedback! Thanks!

Flash is needed for Nasus, because its a really good way to get away when you in trouble. It's also needed with almost every other champion in the game.

Ghost is really good on Nasus because sometimes you just cant catch up to the person you want to kill. Your W is soon going to run out, and they also just flashed. It makes you go very fast. It also scales late game with you.

Teleport can help Nasus get more stacks, but it's not ideal summoner spell you want. Because of it's long cool down, it's not as useful as the other summoner spells in the game. You only use it about 3-4 times a game, whereas for ghost, you can use it plenty of times per game. It can also help in the late game, when baron is open. Example: If you're bot lane, and you see that they are doing baron, you can teleport to that ward and steal it/stop them from doing it.

You should only take ignite if you are facing someone that you know you will destroy in lane. It's not taken often because ghost helps more, but ignite can help if your facing someone with a lot of life steal.

If you are facing someone who gives off a lot of pressure, don't risk fighting him and feeding. Its better off for you to stay under tower and get your stacks that way. If you are fighting someone who isn't giving off too much pressure, just push, but be safe about getting ganked. Once you have ultimate, it's very hard for people to kill you, because of you cool down reduction on you Q.

Usually, mid-late game is just farming top and bot. Try to have your team stall mid lane. Notice that if your team can't stall, you can help them. Your life steal helps the tankiness of your champion, and can help the a big chunk of the fight. Your ult also help with that, as it gives you health. Try to take down the tank first, because you can destroy him with your E armor penetration.
