Dusk and Dawn adds Spellblade damage and an additional on-hit trigger after abilities, while Nashor's Tooth supplies Attack Speed and AP-scaling on-hit damage to stack The Relentless Storm quickly. Riftmaker improves damage and Omnivamp in long fights, and Rabadon's Deathcap amplifies the AP ratios on Sky Splitter and Volibear's passive. Zhonya's Hourglass is the build's only active item and buys time after a Stormbringer engage; Armored Advance adds physical defense. Conqueror and Battle Zeal reward repeated attacks and abilities.
