Instant kills are attacks that automatically set an enemy's health to 0, often in a flashy way. Instant kills are impossible to stack, because enemies can't have any health less than 0. However, it is possible for instant kills to target the same enemy, although the effect would be wasted as only one will actually hit.


Kingdom RushEdit

  • Arcane Wizards can instantly kill an enemy with their Death Ray, turning them into a pile of black dust with ZAP! above the previously intact body.
  • The Musketeer Garrison has a chance to instantly kill a target with its Sniper Shot skill. Enemies instant-killed by this have Headshot above their head.
  • Hacksaw can instantly kill any enemy he is in melee with by using his Tiiiimber! skill. Smaller enemies explode into chunks, while larger ones simply die normally.
  • Oni has a 15%/20%/25% instant kill chance with his Death Strike attack, but it has no unique animation when in effect, other than an enemy's normal death (Although the damage dealt by an Abomination's death explosion will be nullified).
  • Black Hags' Toad's Curse spell turns a soldier into a frog, essentially removing him from play.
  • Certain Bosses can instantly kill soldiers, Earth Elementals and Heroes alike, namely J.T., Sarelgaz, The Kingpin, and Moloch. Vez'nan also has a special Soul Burn attack that instantly kills soldiers, though it doesn't work on Elementals and can't be used after he transforms into his demon form, which has a fire breath attack that one-shots everything it hits.
