Well, LS is pretty nasty to counter since he can deal massive damage while staying alive.
BUT, yeah there's a but...most of his damage output comes from feast, at least until he farms deso or basher, agi heroes(mostly carries) with low health pool and heavy right clicking beat the shit outta naix.
Terrorblade, to be precise.I just hate that dude.I mean, rage quiting after he owns you for like the 15th time is just...oh, ive seen it too many times.
Apart from them, ghost scepter can leave you out of harms way just enough so he's badass steroid spell ends.Then you can permastun him.
And , just to mention, his Infest is just downright awesome.For instance, youre playing Specte and youre free farming peacefully on bot lane.Suddenly, windrunner is coming into your junge.Alone.So you think, ooh okay cool free kill right?Dagger followed by a couple of hits, she gets low, youre already spending the hero kill gold, but then BOOOOM Naix comes out of her(damn that sounds weird) and you die miserably.
