==Summary==
*The Multi Mortar is a defensive building on the Builder Base that shoots splash-damaging Mortar shells at ground units, shooting three to five per blast based on its level. It is unlocked at Builder Hall level 5.
*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.
*The Master Builder can gear up a Mortar in your Home Village that is level 8 or higher (which requires Town Hall level 10) to make it fire in bursts similar to the Multi Mortar. To do so, the Multi Mortar needs to be level 8 or higher in the Builder Base, which requires Builder Hall 8.
==Strategies==
===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, Cannon Carts, and Night Witches behind the tanks, in order to defeat them.
*The Multi Mortar's splash damaging shells makes it good at taking down hordes of low-hitpoint troops, but can be easily distracted by high-hitpoint troops. In particular, they work very well against Sneaky Archers and Skeletons dropped by the Drop Ship, but can also deal good damage to Raged Barbarians, Night Witches and Cannon Carts.
*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.
*The Multi Mortar can stop Bombers from doing too much damage to your base. At relative level, where the Bomber is twice or less than the level of the Multi Mortar, a volley of 4 shots can destroy a Bomber.
===Offensive Strategy===
*Air units are a good option, as the Multi Mortar cannot hit them.
**Drop Ships cannot be attacked by the Multi Mortar, but its Skeletons can be easily wiped out by it, unless they get too close.
*Use tanks such as Boxer Giants or the Battle Machine to distract the Multi Mortar while you swarm the base. Take care that they do not all enter the Multi Mortar's blind spot, otherwise, it will retarget.
*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 Raged 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.
==Upgrade Differences==
*The Multi Mortar undergoes significant visual changes at all levels.
*When initially constructed, the Multi Mortar appears as three small mortar barrels tied together, sticking out of a wooden structure that is also reinforced with ropes.
*At level 2, a fourth barrel is added. The wooden structure elevates slightly and loses its ropes.
*At level 3, the rope holding the barrels together is replaced by a metal band with a copper bolt, and the barrels themselves become thinner and larger. The structure gains additional reinforcing planks.
*At level 4, the barrels become properly aligned, larger, and gain a copper band around the midsection. The corners of the structure are now secured by riveted copper reinforcing planks and the planks are now flat to the ground.
*At level 5, the barrels' copper band is replaced with gray metal with a brass rim, the bolt on the metal band is bigger and also gray. The corners are now secured by a gray metal and a stone foundation is also added below the wooden structure.
*At level 6, large cogs are put on the bolts on the metal band. The rivets on the corners are replaced with metal handles. The shell also changes to a dark stone.
*At level 7, the barrels become slightly larger and the band around them is replaced with brass, the gears on both sides turn into brass, and the bolt holding them in place protrudes out. The handles on the corners is replaced with riveted brass plates and the stone foundation and wooden structure is slightly taller.
*At level 8, the metal band securing the barrels also turns into brass and the bolt use a whiter metal. The rivets revert to becoming brass handles but the plates is replaced with a solid block of brass as its corner. The stone foundation is replaced by a metal one and is slightly taller.
*At level 9, all the brass details of the previous level are replaced by golden details. The gear on the metal band is now thicker and screwed in with a nut, the metal rivets on the band is now also golden. The handles on the corners are replaced by hexagonal bolts and they slope down and curves a bit instead of being flat. Additionally, the sides of the Mortar gain a dark brown metal plating.
*At level 10, a fifth barrel is added. There is no more gap between each barrel, it is one solid piece of metal holding them together, the gear's nut is made out of the dark brown metal and the rivets on the side of the metal piece are now hexagonal bolts.

*These damage per second values are seen in-game and are approximations; it does not necessarily do this much DPS if it cannot utilise the full potential of its bursts.

==Trivia==
*Multi Mortar at level 1 used to fire four shots per burst even though it appears to have three barrels, likely because it established consistency with other levels. It has been changed in the Builder Base 2.0 update.
**The corresponding change was not applied to the level 1 in the Clan Capital, despite it also having only three barrels.
*The Multi Mortar is the only defensive building in the Builder Base that has a unique sound effect when tapped or placed.
