It's Killing Time

It's Killing Time is a gold augment in League of Legends Arena.

Overview

Upon casting your ultimate ability, you apply Death Mark to all enemy champions (8 seconds cooldown). The mark stores a percentage of all post-mitigation damage dealt to the affected target, detonating after 5 seconds to deal true damage equal to the damage stored against them. If this augment's cooldown elapses during the channel of Crowstorm, Hero's Entrance or Grand Starfall, this effect activates right before their first respective damaging effect activates.2

Tips

Interactions

  • The damage from It's Killing Time benefits from ultimate damage modifiers.678 Patch unknown
  • If its cooldown elapses during Fiddlesticks's Crowstorm, Galio's Hero's Entrance, or Pantheon's Grand Starfall, It's Killing Time activates just before that ability's first damaging effect.279 Patch unknown

Bugs

  • Naafiri's W can trigger It's Killing Time's mark on cast, as can her ultimate; ultimate items also trigger when she casts W.1011
  • It's Killing Time does not start counting damage until after Katarina's ultimate ends; this may be intended or a bug.12

    It's Killing Time: For spells with ongoing effects this will trigger if it comes off cooldown while the ability is still active. Galio/Fiddlesticks will now trigger just before they land. Pantheon will now trigger this just before his spear lands.

    It’s Killing Time looks at how much damage the target took after it has been mitigated, then deals its damage as physical damage. We’re changing this from physical damage to true damage, so that it is no longer double dinged by armor, and is also a bit more generalized for magic damage dealers.
