Lich Bane strengthens attacks after cougar-form abilities, while Rabadon's Deathcap amplifies the AP ratios on Javelin Toss and Pounce. Infinity Orb and Void Staff provide finishing damage and magic penetration after a long-range spear; Zhonya's Hourglass is the sole active item and buys time after entering cougar form. In the combo simulation, Electrocute triggers on the third hit and most reliably reinforces the short burst window.
