Lightning Spell info.png

"Electrocute your enemies with bolts of lightning!
Cast this spell at the enemy village to damage buildings and units inside a small area."

  • Summary
    • The Lightning Spell is the first spell unlocked in the Spell Factory and is automatically unlocked once the Spell Factory has finished construction.
    • When this spell is used, a single lightning bolt drops from the sky, damaging all Buildings and enemy Troops in a small radius, with the exception of resource storages and the Town Hall. If a defense (or defensive troop) is struck by the lightning, it is stunned briefly and retargets.

  • Offensive Strategy
    • Lightning Spells are often used to take out an enemy's strong defenses, such as Mortars, Wizard Towers, Eagle Artillery, and Air Defenses, which paves the way for troops to attack. Three or four Lightning Spells will usually suffice against them, unless the building has very high health or the spell is low leveled. 10 level 9 lightning spells can take out a level 4 eagle artillery.
      • In combination with the Earthquake Spell, Lightning Spells can be used in large numbers to destroy high hitpoint buildings such as the Eagle Artillery or Clan Castle directly. Doing this on the latter will prevent the Clan Castle from deploying any defensive troops.
    • A common use is to use lure Clan Castle troops near defenses and then drop a Lightning Spell to eliminate the troops if their health is low enough and simultaneously damage the defenses in its radius. Lightning Spells can be used to kill/injure Heroes directly too.
    • If you need to destroy just one more building to reach 50% destruction, Lightning Spells can be used to destroy a Builder's Hut or hero altars. This is even more useful when it is sufficiently upgraded (as you would only need one when upgraded to level 5 or higher).
    • Lightning Spells can also be used as pseudo-Wall Breakers if necessary. Often your troops will have partially damaged a wall during a raid before being wiped out by the defenses. As a result, other troops may be targeting buildings other than the ones you intended, because a path wasn't opened for them. If the wall is lower level or sufficiently damaged, you may be able to use one or more Lightning Spells to finish off the wall and open the path.
      • However, beyond low-level gameplay, Walls often have a lot of hitpoints, and may require several Lightning Spells (or have too much health entirely), rendering the strategy highly impractical. Furthermore, once Earthquake Spells are unlocked, they easily render the strategy obsolete.
    • Lightning Spells can damage multiple buildings at once if they are sufficiently close together. Keep an eye out for grouped defenses (especially groups of defenses that complement each other), as they can often be severely damaged or destroyed with a few Lightning Spells.
      • When trying to damage multiple buildings at once with a Lightning Spell, there are several ways to visualize its area of effect. One easy visualization is as follows: if dropped at the center of a tile, it will affect exactly 21 tiles - a 5x5 area (centered on the tile where the Lightning Spell is dropped) with the four corners removed.
    • A common beginner mistake is using a Lightning Spell on the Town Hall or resource storages (these buildings are immune to Lightning Spells). However, resource collectors (such as the Gold Mine) can still be damaged by a Lightning Spell for easy resources (this is only recommended if the collector is sufficiently leveled and sufficiently filled, otherwise you risk making a loss).
    • At Town Hall 8, a level 6 Air Defense can be destroyed with 4 level 5 Lightning Spells if done properly, thus making room for an extra Rage Spell that will dramatically improve mass Dragon attacks.
      • If you have 4 level 4 Lightning Spells and can get an earthquake spell (from donation or yourself), that will also destroy a level 6 Air Defense.
    • Both the Lightning and Freeze Spells can disrupt the damage of a single target Inferno Tower. Lightning spells are better used when an Inferno Tower has low health, as the Inferno Tower is only left inactive for a short amount of time.

  • Defensive Strategy
    • Separate important defenses. Having only one important defense (the defending Archer Queen, Clan Castle, Eagle Artillery, Scattershot, etc.) in one area will prevent zap attackers from getting value from their massive amounts of lightning spells.
      • A good way to do this is to have multiple cores in your base, with maybe two or three sections. Separating these sections can also be a good idea, although not really doing anything against lightning spells themselves.
    • Isolating the Clan Castle (especially from the Eagle Artillery) or putting buildings of lesser value will dissuade attackers from destroying the clan castle (as destroying only the Clan Castle would be a waste of most of the attackers' spell space), forcing them to add a poison spell and remove even more spell potential.
    • Separate your Air Defenses from your Air Sweepers. Letting attackers destroy both your Air Defenses and at least one Air Sweeper is a death sentence from Dragon or Lavaloon attacks, as the Air Sweeper is also key in defending against them.

  • Trivia
    • Lightning Spell's brewing time has been reduced multiple times, from 2 hours all the way to 3 minutes.
    • Although the Lightning Spell can be upgraded to level 2 in the level 1 Laboratory, only Troops, and Spells that are already unlocked will appear in the Laboratory upgrade interface. The Lightning Spell will not appear in the Laboratory until the Spell Factory is built (which requires Town Hall level 5). Most players already have a level 3 Laboratory by that time; if so, the first three upgrades will be available as soon as construction of the Spell Factory finishes.
    • Similar to the Bomb and Giant Bomb, the Lightning Spell leaves black scorch marks where the lightning hit, which remains for a few seconds.
    • During the 2013, 2014, and 2015 Halloween event, the spark effect which the Lightning Spell normally produced was temporarily replaced with a swarm of bats.
    • The Lightning Spell's reworked ability to cast a single strike along with momentarily stunning the target made it similar to the Zap Spell from Clash Royale. This rework was added in the 2020 summer update.
      • The Lightning Spell was added to Clash Royale on 4/1/2016 on Clash Royale's soft launch.
    • The Lightning Spell’s rework produces a couple of particles after striking the ground.
    • The Lighting Spell used to have a housing space of two (before the 2020 June update).
      • This update also added levels 8 and 9 to the lightning spell.
