Liandry's Torment strengthens the damage-over-time pattern of Toxic Shot and Noxious Trap, while Nashor's Tooth improves attack poke through Attack Speed and AP-scaling on-hit damage. Rabadon's Deathcap amplifies every AP ratio; Void Staff and Spellslinger's Shoes provide penetration against Magic Resistance. Zhonya's Hourglass is the build's only active item and avoids burst from enemies who reach Teemo. In the combo simulation, repeated attacks stack Lethal Tempo and make the follow-up attack sequence the most efficient.
