Hello,my name is ApplesMan. This is my first guide. Nasus in general is a great champion. In this guide, I will focus on DPS Nasus, the wrecking ball. In my eyes, Nasus wrecks most AD/AS champions such as Master Yi.(I explain later on.) Please actually read this guide, not just use the build. Remember to give me a comment on what I can improve on. Thank you!

Pros:
-Great damage.
-Great chaser.
-Average mobility.
-Can shock people with how much damage he can do when he is low health and has ult.
-Awesome

Cons:
-Squishy until late game
-Mana hungry
-Needs last hits to be effective
-Needs a solo lane or a support

Farming is a MUST on DPS Nasus. If you cannot last hit properly, you cannot do Nasus properly.

I choose these runes on DPS Nasus because they help him do the best that he can in a fight. The ArP marks and quintessences give him the ability to just shred anybody in a fight. With his spirit fire's armor reduces effect and The Black Cleaver, these quints just make him much stronger against anyone wheter its a tank or a squishy. The mana regen runes help him last hit with his Q. Late game, when you've farmed 250+ creeps, the Q knocks some sense into them. Last, but not least, the CDR glyphs allow Nasus to use his Q more frequently. Though it has a low cooldown already, CDR such as blue buff and these glyphs will just allow him to lane forever. In conjuction with his lifesteal passive, no one can stop you.

I take standard 21/0/9 masteries on DPS Nasus. The Archaic Knowledge is more towards his ultimate and E skills. Other than that, everything just beefs up his damage output. I take 9 masteries in utility to help him level faster and and let his blue buff last longer.

I start with Doran's Shield for the extra health, armor, and health regen. I usually farm up until I have enough for my Mercury Treads before I head back my first time. Mercury Treads allow Nasus to be more durable while still be able to burst the heck out of people. Then, I build up my Sheen. Sheen is an overall MUST on DPS Nasus. ITs just makes its easier to last hit, harass, and the extra mana is always helpful. I get a vampiric scepter. When combined with your passive, you can lane forever. Your Q will be healing a decent chunk of your health everytime you use it. Next, is The Bloodthirster. This item is amazing, especially the stacking portion. As a master of creeps, you can farm your Bloodthirster exceptionally well. Then comes The Black Cleaver. This item just pumps up your damage so much. Finish up your Trinity Force. It is everything you could ever ask for in one with the exception of lifesteal which your passive and Bloodthirster provide. I usually don't get any farther into the game because the enemy team surrenders after I pentakilled them, but I build Banshee's Veil and Guardian Angel. The Bloodthirster, Trinity Force, and Black Cleaver provide enough power. Now you build durability. Then finish it off with all the potions to make yourself shine!

I max Q first for the extra damage it provides and then I max my W. Many people have said my E was a better choice to max over W. Wrong. Your W helps you escape, chase, and secure ganks. No one is stupid enough to let you hit them while standing in your fire. Its is better off maxed later when it is helpful in teamfights. So skill priority is R->Q->W->E

I choose exhaust and ghost for my Summoner Spells. Exhaust help you counter AD carries like Master Yi. Exhaust makes them weaker and your W will lower their attack speed while you bash away at them. Ghost helps you chase with your W and escape with your W as well.

All in all, Nasus is a valiant fighter on the Fields of Justice with his incredible fighting capabilities and durability. Please tell me what you think, what you think is good and bad about this guide, and how I can improve.
