How To Counter A Pump Up Lvl 25 Naix?

there is only one thing that can beat a niax of that calibur. Mortred with 6 divine raipers and hopefully she gets a crit right off the bat.

hmmmnn... a fully farmed sandking its preety much simple, you could just use Nerubian Assassin ^_^, with his powerful return damage and 2 blade mails, a HoT, radiance, buriza, and a blink dagger to scape Naix's poison sting(just in case). i guarantee you youll really defeat Naix. ^_^

Hey.. Im really sorry but if Naix has that inventory, no hero has a chance except maybe faceless Void, and that too only if u have as good or a better inventory. Ull need power treads, 2 cranium bashers, butterfly(stacks really well with backtrack) buriza and a lifesteal item of ur choice. (I prefer Mask of Madness for Void so that can be used in chromosphere without the disadvantage of 20% extra damage). U probably know that Chromosphere affects Naix even in his Avatar form. So thats what u will b counting on. So be miserly with ur chromosphere.. :P

Get a hero with bash ability such as Faceless void or a hero with evade ability. Actually naix is not so hard to handle provided he is alone. You can gang rape naix with those disabling spell such as hex, root, net etc. (after the cooldown of his ulti) Dota is something on strategy, if he still has his ulti, let him use it up, then only we rules him in return. No point you go head to head to him while he is in the strongest state. For example, Rhasta used to use his ward to defend the base. We might just go in and let him put the ward, we retreat and then go in again while he is having his ulti cooldown, agree? :)

N'aix is nothing to a well-farmed FV.
