Blackfire Torch strengthens repeated magic damage from Threaded Volley and Unraveled Earth, while Infinity Orb finishes low-Health targets. Rabadon's Deathcap and Void Staff provide Ability Power and percentage penetration; Zhonya's Hourglass is the sole active item to avoid retaliation after a displacement combo. In the combo simulation, Electrocute triggers on the third hit and most reliably reinforces the short burst window.
