  • Multi Mortars are a defense unlocked at Capital Hall level 2. It shoots 4 shots every burst that all deal area damage, which can effectively kill low health troops in swarms.
  • The Multi Mortar shells do low damage by themselves, but medium damage altogether. Additionally, the shells themselves have a fairly large splash radius.
  • The Multi Mortar has a large range, but cannot hit troops which are too close to itself.


Defensive Strategy

  • Place the Multi Mortar at the center of the base to cover as much area as possible and to slow troops from getting too close to it.
    • You can use the Multi Mortar's inability to hit nearby units to your advantage, as the Multi Mortar will target support units, such as the Sneaky Archers, Super Wizards, and Raid Carts behind the tanks, in order to defeat them.
  • Because of its inability to hit nearby troops, it can be good to place the Crusher near it, as it is another area damage defense that deals high damage. However, the Crusher cannot fully cover the blind spot of the Multi Mortar due to its extremely short range. In addition, neither can attack air troops, so that should also be kept in mind when building a layout.
  • Multi Mortars are very good at destroying hordes of Sneaky Archers in 2 shots if they are placed too close with a tank, even when they're invisible.
  • Multi Mortars can be placed near each other for increased effectiveness. However, this makes them incredibly vulnerable to melee units within their blind spot. Splash targeting defenses like the Super Wizard Tower and heavy unit specializers like Multi Cannon can protect these blind spots.
  • Since the Multi Mortar cannot target air troops, it can be wise to put air-targeting defenses such as Spear Throwers and Air Bombs near it.

Offensive Strategy

  • A Super Barbarian is the most efficient at destroying a lone multi mortar, especially in the first few seconds, as its enraged speed means it can easily outrun the Multi Mortar's shells.
    • If the Multi Mortar has other defenses for support, use Super Giants for tanking and Super Barbarians to take down the Multi Mortar without receiving serious damage.
  • Try to get near it, as it cannot hit troops close to it.
  • Try to spread out your troops, so the Multi Mortar cannot hit all of them at once. For example, if you deploy Super Barbarians at one point the Barbarian's health will often be reduced, killing them. Spreading them makes the Multi Mortar lock on 1 Barbarian before locking on another troop.
  • Any air troop can easily destroy it, even the Minion Horde. Just make sure there aren't any air-targeting defenses or anti-air traps nearby to shut them off.

Upgrade Differences

  • Multi Mortars undergo significant visual changes at levels 2, 3, and 5.
    • When initially rebuilt, the Multi Mortar is composed of three black barrels crudely tied together by a rope, mounted on a thin square wooden base.
    • At level 2, the Multi Mortar gets an additional barrel, and the base gets reinforced by pale-colored planks on each side.
    • At level 3, all the barrels separately get bronze bands wound near their muzzles. The base's sides get thicker planks and the corners get reinforced by solid stone. The rope holding the barrels together is also replaced by a thick metal band.
    • At level 4, the base is further reinforced with more stone fittings at the sides. The thick metal band is bronze now, with 2 gears attached to its sides and more support rivets.
    • At level 5, the bronze barrel bands, thick bronze band, its gears and rivets are all made of gold. Additionally, the band receives 4 solid gold fittings at its corners. The wood of the base is completely replaced with gold and the side stone fittings gain another layer.

  • The Multi Mortar was added with the release of the Clan Capital on 2 May, 2022.
  • On September 14, 2023, a balance change reduced the Multi Mortar's DPS at levels 2-5:
    • Level 2: 53 -> 51 (95 -> 90 damage per shot)
    • Level 3: 62 -> 56 (110 -> 100 damage per shot)
    • Level 4: 70 -> 62 (125 -> 110 damage per shot)
    • Level 5: 79 -> 68 (140 -> 120 damage per shot)


  • The level one Multi Mortar fires four shots per burst, even though it has only three barrels. This is likely done in order to establish consistency with other levels.
    • The Multi Mortar in the Builder Base also had this trait until the Builder Base 2.0 update in May 2023.
