Xin Zhao Build
"Smart" hybrid build
Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
So let me explain
I was inspired by this amazing montage by Kshaway here: https://www.youtube.com/watch?v=I5-lWzohDxk
So now, when I look into Xin Zhao, you know what I see? 70% AP healing per third autoattack.
So I wondered, hey, what would be a viable AP Xin Zhao build? I haven't ever tested this, it's mostly for fun.
So let's talk first about the "smart" build. Obviously, it's not "smart" at all, but it's might work a little bit better than full AP Xin Zhao. At full build, it will have a whopping 594 AP if you go by the build. This means every third autoattack will heal you for about 416 HP. The Rod of Ages provides a nice bit of extra health, while Guinsoos and Nashor's both provide attack speed to make your E passive proc faster. Guinsoos and Gunblade provide a nice bit of extra autoattack based damage as well so you aren't completely ability dependent.
On the other hand, you could replace gunblade/guinsoos with a Morellonomicon for maximum CDR or Will of the Ancients for spell vamp fun. A Luden's Echo is for maximum troll, since, well, it's pointless but provides a lot of AP. If you go with a Luden's Echo instead of gunblade, your heal is upped to 473 HP.
