PSA: Take New Fervor of Battle on Illaoi
Most Illaoi's have been smartly taking Deathfire touch because of the E synergy, however we should pay attention to new Fervor. That is 10-60AD at max stacks, depending on level, and illaoi gets 6 of the ten stacks with just an AA-W-AA combo. Throughout the course of the ultimate, she gets 10 stacks and basically gets a free AD item over the course of the game, and we all know how insane Illaoi's ratios are. Not to mention, with Death's Dance, Fervor actually makes Illaoi heal for more, which can be further capitalized on by Runic Armor and Fearless.
So start taking Fervor on Illaoi, and watch as you scale harder than Illaoi ever did before. Its just plain filthy.
