Stormsurge supplies bonus magic damage and Move Speed after Kennen deals a large burst, while Infinity Orb helps finish low-Health targets. Zhonya's Hourglass lets him survive the critical duration after entering the enemy team with Slicing Maelstrom. Rabadon's Deathcap and Void Staff provide Ability Power and percentage magic penetration, and Spellslinger's Shoes add more penetration. In the combo simulation, Electrocute triggers on the third hit and most reliably reinforces the short burst window.
