answers before you ask :)
why not fervor?
cuz after nerfs it sucks
why is this build better than ap one?
cuz after mini rework his w with full ap fizz really suck like you will almost never be able to stay in fight with ADC just to stack w passive for 2 sec,with tank fizz its much easyer
also you have rly big base damage on all spels (ult base damage on 3 lvl with max range and no ap is 500 dmg)
why that boots?
cuz they are like rly good cuz sunfire is dealling magic damage,iceborn too,your basic attacks too
you can like proc it so much cuz if you last hit minnions w cooldown is 1 sec!
