Please, update

Great guide, Tiamat really works well. Just one thing, you won't reduce anyone's armor below 0 because Armor Penetration is calculated after Armor Reduction. Example:

Let's say the enemy has 60 Armor. You have 40 Armor Reduction through SS and 45 Penetration through Black Cleaver. The enemy's armor is reduced by 40 and the remaining 20 are penetrated, leaving the enemy at 0 armor. That's because penetration can never penetrate below 0.

Okay I'll just point out general Nasus things:

1) Very flexible character in terms of items since his Q is his greatest D-Output tool.
2) Farms well
3) Doesn't need to auto-attack much to do damage.
What does that mean? Well essentially it boils down to you needing Lucidity to actually do significant dmg (Because let's face it, 10% CDR is also better for stacking Q and all your other abilities). What about the Veil? I strongly encourage you to find a better surviving item, because while it IS a good item, you need to be flexible and because of that, I recommend leaving that slot open so that if the enemy team is AD heavy, you can counter that.

k i just tried it i went 14/3/2 (2 ks's from an alistar) best game ive had in a while

Too squishy, you will get focused and eaten in teamfights because of low health and armor, even with your ultimate.

New fave champ thanks for a great build.

@Wintermond, Downvoting because its old? The build still works great.

Outdated, should be archieved.

Amazing build. You've put me back into playing Nasus, he was the first champ I ever played and I liked him. But I had no idea how to play him. Now I dominate with him, great work and +1 from me.

Tried this after the recent buffs...ended up acing the whole enemy team by the end (granted they kind of stunk, but it's a good feeling), also nice to see that Tiamat isn't completely useless on every champion ever.

Anyway, keep up the good work! ^.^

This guide is amazing! Since I started using it, Nasus has become my main. Usually I finish a game with 10+ kills and <4 deaths (most of which come from the beginning of the game).

I follow the guide up until I have the Black Cleaver, then instead of getting Banshee's Veil, I've been trying to go for Madred's Bloodrazor (for extra DPS) or Frozen Heart (for faster cooldowns and more mana)

Tried it and was quite nice, tho we still lost but i did good =). Late game i would get, instead of banshee veil, madreds bloodrazor and if get focused, instead of lifesteel, guardian angel (ot infinity edge and screw defense =P-but didnt try this). Tho life steal late game isnt much good since burst from enemies is just too high. But i am more newish so might not know everything =P and thanks for great guide tips.
Oh i could easily kill 1v1 anyone lategame (if not escaped or had longish stun in which he burst me down sooner), early game was little low but not bad and middle was solid. And that game was quite long and very close (almost won) and managed to get little more than 300 bonus damage on siphion strike, which was imba on squishies =P.
(commenting only items, for ss i have to agree with others to lvl it first)
