“Bolts of lightning damage and stun up to three enemy troops or buildings with the most hitpoints in the target area. Reduced damage to Crown Towers.”

The Lightning is an Epic card that is unlocked from the Frozen Peak (Arena 8). It is a multi-damage, air-targeting spell with a medium radius and very high damage. When used, it can stun enemies in its radius for 0.5 seconds. The three troops that are targeted are always the three that have the highest hitpoints within its radius. It is a light blue liquid encased in a large vial. A Lightning card costs 6 Elixir to deploy.

  • Lightning does massive damage, though not as much compared to the toughest units such as Lava Hound or Giant. It is still useful as two of its strikes can cripple or obliterate support units.
  • The Lightning spell can be used to finish off Crown Towers with low health or to one shot all troops with less than or as much health as a Phoenix.
  • Lightning is extremely effective against the Wizard and Witch, especially next to enemy Crown Towers, as it will deal a sizable amount of chip damage for only 1 extra Elixir while also still being able to strike one more unit.
  • Lightning can be effectively used to counter Three Musketeers to create a 3 Elixir advantage. The player should keep in mind that they should avoiding hitting the Tower if they would like to hit all 3 of them.
  • Lightning is effective in Lava Hound decks as it can quickly one-shot multiple threatening ranged troops such as the Wizard and Archer Queen, both of which can quickly destroy the Lava Hound and any support units behind it.
    • This can also be done against cheaper units like the Hunter or the Night Witch, but the high Elixir deficit that this would cause may or may not be worth the risk depending on the situation of the match.
  • As the Lightning strikes once on each target, it will strike fewer than three times if there are only 1 or 2 enemy troops or buildings within its radius, reducing its value. Thus, the player should try to use it only when there are sufficient targets in the target radius.
  • Since Lightning prioritises striking the targets with the highest health, placing a troop with more health next to a low health unit will block them from being struck.
  • When using the Lightning, it is important to designate the targets of the spell in its radius. It is best to refrain from showing the opponent the Lightning until the opportunity for the highest Elixir advantage possible arises.
  • If Lightning is used on a shielded unit, only the shield will be destroyed. This is because both the shield and the unit are both considered the same entity. This is not the case with units such as Battle Ram; Lightning will destroy the Battle Ram and then the Barbarians, as both are considered separate entities which Lightning can retarget onto.
  • When trying to destroy the enemy Crown Tower at the last few seconds of the game, be careful, as any medium-high hitpoint units in its radius will be targeted instead by the Lightning, as in such situations the Crown Tower will have relatively low health, possibly even lower than a Skeleton. Instead, cast the Lightning towards the corner of the Tower while it is within its radius to avoid targeting other units surrounding the Tower.
    • As for the defending player, pay attention to the Crown Tower's health, and place a swarm card accordingly. Battle Ram and Zappies are especially effective, due to having a lower Elixir cost for the highest range of possible Crown Tower health that would be needed to finish it off.
  • The Elixir trade-off for using a Lightning can be very high, giving the enemy an Elixir advantage in most cases. However, the Lightning spell is ineffective against units with extremely high hitpoints such as the Giant or P.E.K.K.A.
  • An alternative to the Lightning is the Rocket. Although Rocket costs the same amount of Elixir, takes more time to deploy, has some travel time and has a smaller AOE, it does massive area damage that is capable of taking out or heavily damaging many more targets.
  • The Lightning is very effective against the Sparky as it will reset Sparky's damage while also dealing high damage to her and other supporting troops. However, a Lightning will not take out a Sparky of the same Level, meaning she is still dangerous if she is still being protected by a tank.
  • The Lightning is very effective against the Inferno Tower and the Inferno Dragon since it can not only heavily damage these units, but also reset their target lock on troops, thus making them take longer to defeat them.
    • While the Lightning may stun and cripple an Inferno Tower, it is a negative trade since the Inferno Tower can still damage pushes and the building costs 1 less Elixir than the spell itself. Try also hitting something else to maximize the value.
  • Lightning can also reset charging troops with its stun, so can be used in a pinch to reset charges of the Prince, Dark Prince, and Ram Rider.
    • However, with Dark Prince, you need to destroy his shield first, as otherwise Lightning will just have most of its damage canceled by the shield.
  • Lightning can immediately destroy an Archer Queen of equal level, although it is a negative Elixir trade. The player can hit 2 more units or buildings in its radius. Since it is a spell, Lightning can hit the Archer Queen even with her ability active.
