Vayne ADC vs Tahm Kench Support Matchup

Why Vayne is favored

Tahm's engage and durability are a poor fit against Vayne's tools: Condemn(E) makes Abyssal Dive(W) harder to use, Tumble(Q) can evade the dive, and Silver Bolts(W) deals max-health true damage. Players on both sides call out these interactions, which let Vayne resist Tahm's engage and punish his tankiness.

How to play as Vayne

Stay behind minions when Tahm is looking for Tongue Lash(Q), and watch your passive stacks; the wave can block his lash, but three stacks let him stun you.

Save Condemn(E) for Tahm's Abyssal Dive(W) attempt, and be ready to Tumble(Q) away from the telegraphed engage; Tahm players say Condemn makes the dive harder to cast or land, and Vayne players say she can dodge it.

Don't auto-for-auto into Tahm while his ADC can hit you freely; when you have a safe window, keep Silver Bolts(W) on him to punish his high health with true damage.

Silver Bolts(W) deals max-health true damage, and Condemn(E) knocks Tahm Kench back; Tahm players specifically cite both as reasons Vayne is difficult for him to face, including that Condemn makes Abyssal Dive(W) harder to cast or land.

Tongue Lash(Q) hits the first unit in its path, but each champion hit builds An Acquired Taste(P), and three stacks let Tahm stun with Q; Vayne players recommend using minions to block the lash and deny stacks.

How to play as Tahm Kench

Try to draw out Condemn(E) before committing to Abyssal Dive(W), and don't extend a fight while Vayne can keep applying Silver Bolts(W); Tahm mains call out both as reasons this matchup is difficult.
