  • The damage is dealt after a short delay.
    • Becoming untargetable will not prevent the effect from occuring.
  • The 3 second timer is non-refreshing - the third stack has to be applied within 3 seconds of the first.
  • Non-damaging abilities also apply stacks - this includes abilities (e.g Apprehend Apprehend, Wither Wither) and item actives (e.g Righteous Glory item Righteous Glory, Twin Shadows item Twin Shadows).
  • Each of Aurelion Sol OriginalSquare Aurelion Sol's stars count as a separate ability for the purposes of applying stacks.
  • Despite not being abilities, stacks can be applied by Sunfire Cape item Sunfire Cape's aura.
  • The initial Root icon root of Dragon's Rage Dragon's Rage already applies the stack from the ability, and since the delay of Electrocute is shorter than the delay between the root and kick of Dragon's Rage Dragon's Rage, the latter does not go on cooldown if the target is killed by the Electocute.

Map-Specific Differences

  • Cooldown changed to 15 − 10 (based on level) seconds.


"We called them the Thunderlords, for to speak of their lightning was to invite disaster."
Rune caption
  • Electrocute is almost identical to the removed Season 2016 mastery Thunderlord's Decree mastery 2016.png Thunderlord's Decree. The primary distinction between the two is that persistent area of effects and multi-hit spells can no longer generate multiple stacks per cast - e.g. Dark Wind Dark Wind, Ethereal Chains Ethereal Chains and Tormented Shadow Tormented Shadow.
    • In addition, Electrocute requires that all three abilities hit within one three-second window, while Thunderlord's Decree only required three seconds between each ability. This makes it harder to activate for champions with slow combos, especially champions who primarily use basic attacks (at least 0.667 attack speed is required without using abilities).
