Hi there, my name is Reagonfly, i'we played since season one and this is my first build, Tanky OP Nasus.
For play it well you need to remember only one think, stay Safe, in late game you will be strong enought to hold 3-4 enemies at once and kill all of them shortly, until you are shure to hold 2 or 3 at once stay safe and farm your Q, if you had some problems stay under tower, the farm will come to you :)
