this build seems like a waste, may be mana starved at the begining for a lot of ppl but it is because of the constant obession with spamming SF. The SF spam is GREAT early game for minion farming, however all those minions you get with your SF doesn't go toward your Q when they otherwise could.

Also, the problem with getting those mana items at the beginning causes your late game to suffer hard. Because nasus has 0 mana trouble late game. I'm not going to minus your build, I just hope that you re-evaluate your position on these mana heavy items.

It's not that nag. It has amazing staying power in laning phase. One SF can destroy a whole creep wave, meaning you farm like a beast and gain gold equal to a kill every 2-3 waves. And unlike other builds, here you can farm this way all day long, not going to base but once.

Of course, some teams foil this. The key to farm up well enough is to be turret-protected all time, meaning that if the enemy controls creep waves well, you might have a hard time. In particular, Pantheon is a char like that, with capability to farm effectively, as well as abusing stun to punish you for not hugging your turret, even if you leave to score a Siphoned last hit or two. If that is the case, try to change lanes or outharass the enemy. SF is a viable harass tool in this build since its high mana cost is offset by a large mana pool.

manamune is very interesting. +1 for that. I kinda dont like the rest of your purchases. I see why you bought those items but it dont think it would be vey effective against a lot of team comps. DPS/Tank nasus is a nag to build though. I just think that this build would be to interruptable by certain team comps and you couldnt build you mana pool correctly.

Just some thoughts

14100 Dollars For This Build, Sounds Pretty Decent Since Nasus Can Farm Like A Boss.
