• "Going in combat by affecting an enemy champion" refers to any form of effect that makes you go in combat. This includes effects that don't deal damage (e.g TrundleSquare Trundle's Pillar of Ice Pillar of Ice, placing ZileanSquare Zilean's Time Bomb Time Bomb, BardSquare Bard's Tempered Fate Tempered Fate).
  • Emerging from brush does not trigger Sudden Impact.
  • KalistaSquare Kalista's Martial Poise Martial Poise will trigger Sudden Impact, allowing her to have it active almost the entire game.
  • Hextech Protobelt-01 item Hextech Protobelt-01 will trigger Sudden Impact, allowing champions that do not have any dash, blink, or that do not utilize stealth or Teleport Teleport, to activate the rune up to every 40 seconds. The cooldown can be futher reduced with Cosmic Insight rune Cosmic Insight and Ingenious Hunter rune Ingenious Hunter.
  • The effect does not trigger on UdyrSquare Udyr's Bear Stance Bear Stance[1] or DariusSquare Darius' Noxian Guillotine Noxian Guillotine, as they only cause the champion move in closer to their target, not necessarily "dash" in the traditional sense.
  • BardSquare Bard's Magical Journey Magical Journey can activate Sudden Impact, and hypothetically other champions entering the Magical Journey Magical Journey will get the effect.
  • Rootcaller Rootcaller's dash can be used to trigger Sudden Impact. However, this only happens if the ability makes you move. Using it at point-blank will not trigger it.
