so i read this, and am curious, is this guide still valid in 5.20? i'm wanting to try this, as it sounds fun and i've always thought azir was cool, but i've never used him before, i'm debating whether or not i get him, i'm a primary jungle, and trying to figure out whether or not still works

In the jungle I wouldn't say Liandry's is that good of an item as the other choices (Rylai's and Zhonyas, for example) provide better defenses and you need the item slots for offensive items. In this case, Liandry's does offer a bit of offense AND defense, however it is overshadowed by the raw stats the other items give.

Would liandry be a good item to build on azir? and if so, when would be the best time to?

I wrote a long *** 7 paragraph reply stating with mathematical proof why you're wrong, but was on my phone and changed tab to get a bit of info and it refreshed and lost the details. I might add tomorrow, but Sufice to say you're quite ignorant and should check the patch note details, as well as his actual info on say lol wiki or something similar. His soldiers do scale with his AS, and I need to test it but his soldiers now make a secondary soldier attack for his soldier damage (12.5-42.5 +15%AP per phantom soldier due to the damage reduction for soldiers beyond the first), OR even stronger they don't do the base damage but do proc on hit effects, which is the usual interaction of sated, in which case you can combine Nashors and th Arcane Blade mastery for (15 +20%AP per phantom soldier hit).

Considering you can get 3 soldiers out with ease if you pick your moment and fights, in 2 auto hits you're capable of either
((soldier base damage*2)+(7*0.25*soldier base(the reduced damage hits))+(a total of 225%AP)
or in the second situation and even stronger;
((soldier base damage*2)+(3*0.25*soldier base(the reduced soldiers)+(15*3)+(a total of 240%AP)

And damn you get allot of AS with a nashors, sated, and your W passive AS included. You can out attack speed average arc builds, and god knows such a ridiculous AP scaling beats them in that regard as does your ability to position them and outrange most opponents.

reallyyyy bro?? nashors tooth? it seems that you dont know what the heck you are writing. Nashors tooth no longer works on azir, it doesnt proc on hit effects in patch 5.17. And if you have 50% attack speed from devourer, you dont really need any more attack speed. Fail guide, but keep trying
