Luden's Echo improves Death Ray poke and wave clear, while Lich Bane adds Spellblade damage to the empowered attack after Siphon Power. Rabadon's Deathcap, Infinity Orb, and Void Staff complete AP, finishing damage, and penetration for evolved abilities and Arcane Storm. In the combo simulation, Arcane Comet triggers from the first ability hit and gives repeated poke the most reliable expected damage.
