Nasus is by my opinion the best solo topper. He has a good amount of damage, is a good tank with life steal with causes him to get good substain in the lane.

Nasus will pwn almost every opponent he faces. Makes them forget your ult when u are 1v1 or 1v2. When you are running low on health, activate it, and you will usually kick their butts and get a kill (or a double if you are kicking ballz)

I am maxing Siphoning strike first. This is because Siphoning strike is Nasus' most important spell.
The second spell i max is Wither. That is a really good cc spell which makes Nasus op.

Do not bother upgrading Spirit fire at all. This will only make you lose mana and dont do that much damage.
