Lightning

"Bolts of lightning hit up to 3 enemy troops or buildings with the most hitpoints in the target area. Reduced damage to Crown Towers."

Summary

 * This card is unlockable from the Goblin Stadium (Arena 1).
 * When cast, the Lightning emits a similar animation to its' counterpart, found in Clash of Clans, and targets 3 troops/Buildings with the highest hitpoints, within its AoE (Area of Effect).

Strategy

 * This spell can be used to finish off towers or damage high hitpoints troops such as Giants.
 * The Lightning targets the 3 troops/Buildings within its damage radius, with the highest hitpoints, as stated in the spell's description.
 * This means it is useful for weakening troops like Giants so that they are easier to kill.
 * This spell is EXTREMELY effective against Barbarians, Wizards, and Witches next to enemy Crown Towers, as the spell targets 3 troops/Buildings with the highest amount of hitpoints in its' radius.

Trivia

 * On 19/2/16, the Balance Update decreased its Crown Tower damage by 20%.
 * The Lightning Spell is the first spell unlocked in Clash of Clans, however the Lightning is not the first spell you unlock in Clash Royale.
 * Unlike Clash of Clans, the Lightning can only hit three Buildings or troops, whereas in Clash, it can hit any troops or buildings in its' damage radius.
 * The Zap serves as a weaker alternative to the Lightning, with 1/3 of the spell's Elixir cost, and approximately 1/3 of the Lightning's damage. However, the Lightning spell is limited, as it targets up to 3 troops/Buildings with the highest hitpoints in its' radius, while the Zap deals damage in a determined AoE (Area of Effect).
