for the nasus mains out there... try my build

smite/flash, spellbook with sorcery, all the cdr, with future and watch. coin 3 pots start, rush cull and sheen, glacial/gem depending on lane. when finished cull, finish with a vamp cepter (for bork). if you have the razor, you can easily duo baron when it pops. just to be clear, THIS IS NOT TANK this is sustain for small brawls. attack speed helps with q cd, so you pump them out faster. having bork and blo raz means you don't need stax, so you can focus on team fights. i myself roll heal for the most part after the first back. zzrot last item to place down to zoom zoom during teamfights. dont be shy to pop ur ult to get quick stax, and remember to ward with the jungle item. try to have room for a control ward as long as you can. typically, my end game build is triforce/gauntlet, bork, green blo raz, rg/sv/fh, zzrot, mercs ( i don't like tabs, i like moving during teamfights). you should hit 18 first, or close to it.

if you're having a tough time early on, start maxing e, buy dorans ring and dark seal. 2 points in q, rest in e. your stax will suffer, but you will get your blo raz faster so it wont matter.

want some proof?
