Rage

"Increases troop movement and attack speed by 40%. Troop buildings and summoners deploy troop faster. Chaaarge!"

Summary

 * This card is unlockable from the Barbarian Bowl (Arena 3).
 * The Rage spell increases the damage and movement speed of troops in the spell's AoE (Area of Effect).

Strategy

 * The Rage spell can be used to increase slow movement speed troops, such as Golems, P.E.K.K.A.s and Giants, with higher hitpoints.
 * The spell can also be used to boost Buildings, such as the Barbarian Hut or Goblin Hut duration to spawn troops, as well as the X-Bows rate of fire to extremely high effectiveness.
 * The Rage can also be used to help rushes and with its low cost, it can assist the Prince, Hog Rider, and other troops destroy an Arena Tower easily.
 * It is most effectively used when rushing to destroy the King Tower or when defending yours since it will be able to affect both your units and your buildings.

Trivia

 * On 29/2/16, a March Update made the Rage spell's effect fall off after 2 seconds, when troops leave the Rage area.
 * On 23/3/16, a Balance Update increased its movement and attack speed boost to 40% (from 35%) and decreased its duration by 20%.
 * The Rage is very similar to Rage Spell in Clash of Clans, except that the spell increases attack speed instead of damage, can also speed up the fire-rate of Buildings, such as the X-Bow, and boost the spawn speed of other buildings.
 * Upgrading the Rage spell does not affect its AoE (Area of Effect) troop movement and attack speed buff, only the spell's duration.
 * The Rage spell is the cheapest Epic with a determined cost of 3 Elixir, as the Mirror can be cheaper but has no determined cost.
