Tips

Fan the Hammer can work with Briar's Q cooldown-reduction combo.4

Tristana is probably one of Fan the Hammer's best users.5

A full-crit Fan the Hammer build is recommended for Nocturne.10

Fan the Hammer is included in an AP Akshan build alongside Double Tap, Marksmage, and Critical Missile.11

A full-crit Fan the Hammer build with Vi can take down a target in two or three basic attacks.12

  • Dusk and Dawn followed by Sword of the Blossoming Dawn and Echoes of Helia is a build that needs Fan the Hammer to reach full power, though other on-hit augments also work.13
  • Critical Missile, Vulnerability, Fan the Hammer, and Dual Wield can make a strong Akshan combination.14

A support Xin Zhao build with Fan the Hammer can heal allies heavily and make Xin Zhao very hard to kill.15

Interactions

Ezreal's Q can trigger Fan the Hammer as an on-attack effect.1617

With Gnar or Vi, Fan the Hammer can proc their passive twice instantly.18

  • Fan the Hammer can help Tristana trigger her E with one basic attack, similarly to Dual Wield.19
  • Caitlyn's passive does not stack with Fan the Hammer.20

With Twitch, Fan the Hammer applies all passive stacks in one basic attack.21

Fan the Hammer applies Kalista's spears.22

Vayne's W damage is unaffected by Fan the Hammer, so it deals full damage.2324

Fan the Hammer can trigger Vayne's W, which has no cooldown, multiple times; the resulting W damage is not reduced by Fan the Hammer.252623

Fan the Hammer stacks Tap Dancer quickly on Urgot.27

Fan the Hammer stacks Gnar's passive to its maximum in two basic attacks.28

Blade Waltz procs on-hit effects, not on-attack effects.29

Bugs

With Scavenger, Fan the Hammer can appear among a champion's augments when they end up with seven augments total; whether this is a bug or intentional is unclear.30

Kalista with certain items, mostly Reaper's Toll, can trigger an infinite feedback loop on the server; Reaper's Toll, Fan the Hammer, and Bloodrazor may be involved in the repeated triggers.31

Blade Waltz may fail to trigger Fan the Hammer.32

History

Since patch 26.10, Fan the Hammer has two levels instead of three, with a per-direction cooldown of 7 seconds at level 1 and 5 seconds at level 2.33

In the eight-teams-of-two format, Fan the Hammer, Double Tap, Reaper's Toll, and Vulnerability were used together as a strong combination.8 Earlier Arena format

Fan the Hammer with Mystic Punch allowed attacks to be queued while the bolts traveled, allowing the bolts to hit six times.38 8x2 duos

Fan the Hammer and Shen's Q applied on every bolt instead of only the first three; empowered Q after passing through a champion seemed to deal more damage than expected.39 8x2 duos
