Similar Items


  • The base timer for Storm's Edge is 3 seconds, but since Stormrazor grants attack speed, the timer is reduced to 2.4 seconds (except for JhinSquare Jhin).
  • On JhinSquare Jhin, the timer only reduces with his base attack speed, building bonus attack speed (items, runes, etc...) will not affect the timer. This sets his Storm's Edge timer to 3 - 1.99 (based on level) seconds.
  • Storm's Edge's critical strike does not take priority over a standard critical strike (e.g it will not apply the critical modifier or movement speed to either FioraSquare Fiora's Bladework Bladework or ShacoSquare Shaco's Backstab Backstab criticals).
  • YasuoSquare Yasuo's Steel Tempest Steel Tempest and GangplankSquare Gangplank's Parrrley Parrrley count as a basic attack for Stormrazor and will go on cooldown even if no targets are hit.


  • Stormrazor item Stormrazor synergizes well with Statikk Shiv item Statikk Shiv as the empowered attack counts as a Critical strike icon critical strike, increasing Statikk Shiv item Statikk Shiv's damage.
  • Storm's Edge's damage reaches its maximum (200%) at 30% critical strike chance, which can be obtained by buying any one of Runaan's Hurricane item Statikk Shiv item Rapid Firecannon item Phantom Dancer item or by buying Infinity Edge item Zeal item.
  • When only considering basic attacks without additional effects, the effectiveness of waiting versus attacking is not dependent on bonus attack speed and is given by critical damage / (3 × base attack speed).
    • This means that with more base attack speed it is less effective to wait for Storm's Edge.
    • Without critical strike chance, the only champion in the game on which it is better to wait for Storm's Edge is GravesSquare Graves.


  • The passive Storm's Edge was called Wind Blade in development.
