You can unlock it in Builder’s Workshop (Arena 6)
Long range unit with area damage. It can be used as offensive or defensive building.
The Mortar is very over powered card with big radius. But in next update will be decreased it power and change deploy time.
Can be placed to eliminate large swarms of troops but is less effective on higher hitpoint troops like the Giant.
For best effectiveness is good to place the Mortar in the center of the player’s territory.
The Mortar can target the enemy’s Crown Towers from the player’s own side.
With its cheaper cost and ability to deal area damage to Crown Towers, the Mortar can be used as a cheaper and less risky alternative to the X-Bow.
