Mortar

(Its cost actually is 4 elixir, we are going to update the image)

"Defensive building with a long range. Shoots exploding shells that deal area damage. Cannot shoot at targets that get very close!"

Summary

 * This card is unlockable from the Royal Arena (Arena 6).

Strategy

 * The Mortar can be placed to eliminate large swarms of troops, or assist in eliminating medium or high hitpoint troops.
 * Its low hit speed means that it has lowered effectiveness on higher hitpoint troops, such as the Giant.
 * For effectiveness, the Mortar can be placed in the center of the player's territory, preferably closer to the King's Tower, so opposing troops cannot get to the Mortar & Tower without defensive resistance.

Trivia

 * On 11/01/16, a balance update decreased the Mortar's lifetime to 40 seconds.
 * On 2/2/16, the February Update decreased the Mortar's cost to 4 (from 6), its damage decreased by 40%, its lifetime to 20 sec (from 40 sec) and its range decreased to 12 (from 13).
 * Reason: "Mortar has also been one of the least used cards, as the X-Bow is simply a more compelling choice in most cases. A cheaper cost, shorter lifetime and lower range should clearly differentiate it from the X-Bow, and make it a tempting play on both offense and defense."
 * The Mortar is originally featured in Clash of Clans, with identical mechanics.
