Darius

Darius is a lane bully, you will have a lot of trouble in the early game. I personally start to fight darius around lvl 9, when you have about 150 stacks, then its safe to fight him if you have stacked up CDR. You can choose what to max, if you cant sidestep his Q, max W, if you want to deal more dmg to him, max E to the third rank. Then after lvl 11 go back to maxing W

Camille

Camille is just broken imo, there is no way to dodge her Q, so you will take a lot of truedmg. You just have to let her push the lane and stack safely under turret. You're definetly stronger after lvl 6, but she still can kill you or just run away with her E, so be carefull when you're picking a fight,

Jax

Dont even try to fight him when he has his E ready at the early levels, since his E blocks your Q, you cant do a shit to him. So similiar to camille, just stay back and stack freely, if you get your sheen + some cdr, you can probably fight him.

Teemo

This little satan is really annoying, he can use his Q to deny you stacking, this is probably one of the worst lanes for nasus. He will poke you down with his abilities and AA, doesnt even help when youre sitting under turret. you need your jng to be smart and gank him when he will be overextending, because he cant run away if you W him

Shen

Shen is basically the same as jax, he can block your Qs with his W + he has a lot of dmg thru his Q. You will definetly have to stay back for the first levels, do not try to fight him early on.

Kled

Kled is also a pain in the ass, but its doable, just watch out for his Qs, and ur good to go. Grasp will save your ass in these kinds of matchup, stack some armor first, so i recommend to go for G. Shroud and then you can do sheen or kindlegem.

Renekton

Renekton is similiar to darius, you cant fight him early on, even after 6th lvl, he is still stronger than you. But when you achieve some stacks, and CDR you can pretty much win the fights.

Garen

Garen is not that much of problem when he decides to go for E conq build, but with Q grasp, its really hard to do something, since his Q breaks your W. So you have to be careful about that. Similiar to darius, get 150 stacks + sheen and some cdr items and he has no chance at all to fight you.

Akali

Just be under your tower and stack, this champ is pure cancer, if you wanna to go all in ,she will just hide like a pussy and you cant do a shit. so on the lane with her, just safely stack.

Olaf

Olaf isnt seen on toplane too much, but if you meet him, you cant win early fights, and then he can break your W thru his R. BRAMBLE VEST is needed in this kind of matchup, so be sure to pick one up

Aatrox

Aatrox will not harm you at all at the lvl 1-4, but at lvl 5 his Q starts to do a lot of dmg, so he will punish you every time you go for stack. Bramble vest is needed in this matchup to deny the healings, after some stacks and R you can beat him easily.

Malphite

Every character in the minor category is basically free stacks, but be carefull at lower levels especially against malph, he can set up ganks etc. so be mindful about that, otherwise its easy matchup, you can sustain his poke even in the early game, just make sure to not let him use the whole rotation on you.

Maokai

Mordekaiser

Be carefull about morde, lvl 1-3 is freee stacks, just dont let him E you, if you buy SV and sheen, you can beat him even in his R. But at the levels 4-9 he is stronger than you.

Ornn

Gangplank

The early is a bit painful due to his poke, he can W out of your W. This matchup is somewhat good only because you can stack his barrels, but be carefull and do not let him poke you too much.

Illaoi

When against a illaoi, you just have to dodge her E, or run away from it as soon as possible, Good thing about this match up is that you can stacks her Tentacles, so its really good for you. but she can beat you even when you have 6, if she lands her E, dont even try to fight her.

Yorick

Yorick is similiar to Illaoi, he is definetly stronger when his R is on, but there is a redeeming aspect that you can stacks his ghouls, which is good, you will always oneshot the ghouls with your Q. So you can get big stacks. But still, be carefull, you cant fight him while he has his R up.

Vayne

Vayne is my go to ban, if you meet her at top, your only hope is jungler, You will always take a lot of dmg while going for stacks cuz of her W, even after lvl 6 sne can beat you thru her W. I personally like to max W at the first levels so you can slow her more.

Riven

Riven is also a bad matchup, cuz of her dashes, your W doesnt help at all agaisnt her, you just need to get tanky so you can beat her, play safe untill you're stacked up.

Fiora

Fiora is a pain thru her truedmg, but its a still doable matchup, do not fuck up your early game, dont give her too much kills and just stack up.
