Patch 26.13 Tahm Kench Ethereal Weapon build for ARAM Mayhem: 56.3% data, Q on-hit logic, Dusk and Dawn, Heartsteel, and Tank Engine.

June 27, 2026

Patch Position

Ethereal Weapon lets Tahm Kench Q apply on-hit effects. Tahm with Ethereal Weapon is T1 at about 56.3% win rate, so this is a conditional build with real data behind it.

Core Mechanic

Tahm Q is long range, slows, and stacks his passive. Ethereal Weapon links that spell hit to on-hit effects, making Heartsteel and Dusk and Dawn easier to trigger from safer positions.

Ethereal Weapon needs support. Without on-hit items or a tank base, it does not automatically turn Tahm into a burst champion.

Items and Playstyle

The stable route still starts with Heartsteel, Warmog, and resistances. Add Dusk and Dawn after Ethereal Weapon is online; Shiv or Deathcap only fit when the team already has enough frontline.

FAQ

Q: What does Ethereal Weapon make Tahm Q trigger?

It makes Q apply on-hit effects. With Heartsteel or Dusk and Dawn, Tahm can control and trigger damage from longer range.

Q: Ethereal Weapon or Tank Engine first?

Tank Engine is more stable because it improves Q range and frontline pressure. Ethereal Weapon has higher on-hit ceiling. Together, they form the ideal high-roll path.
