Clash of Clans Builder Base Multi Mortar Guide

Introduction to Clash of Clans Builder Base Multi Mortar Guide

The Multi Mortar is a powerful splash damage defense in the Builder Base, available starting at Builder Hall level 5 in Clash of Clans. Unlike the regular Mortar, the Multi Mortar fires multiple shells per volley, with the number increasing as it levels up. At its highest levels, it can launch up to five shells in a single attack, significantly improving its damage output.

Each shell deals moderate damage, but the true strength of the Multi Mortar lies in its ability to hit multiple targets within a large splash radius. This makes it highly effective against groups of ground troops, especially swarms of low-health units like Raged Barbarians and Sneaky Archers. However, it has a blind spot and cannot attack enemies that get too close, similar to its Home Village counterpart.

Its long-range attack allows it to target enemies from a safe distance, making it a crucial part of Builder Base defenses. Proper placement ensures it remains protected from direct assaults while still covering key areas of the base.

At Builder Hall 8, players can unlock a special gearing-up feature by upgrading the Multi Mortar to level 8 or higher. This allows them to modify a Mortar in the Home Village to fire in bursts, similar to how the Multi Mortar functions in the Builder Base. This upgrade improves splash damage capabilities in the Home Village, making it more effective against swarming ground troops.

Defensive Strategies

The Multi Mortar is most effective when positioned at the center of the base, allowing it to cover a wide area and strike enemy troops before they reach key structures. Keeping it well-protected ensures that it remains active throughout the battle, continuously dealing damage to approaching attackers.

One of its primary targets is support units like Sneaky Archers, Cannon Carts, and Night Witches, which tend to stay behind tanky front-line troops. The Multi Mortar’s splash damage is particularly useful against groups of low-hitpoint units, quickly eliminating them before they can deal significant damage. It is also highly effective against Raged Barbarians, preventing them from overwhelming defenses in large numbers. Additionally, it can stop Bombers from causing excessive damage to walls and buildings, as a four-shot volley is enough to take them out.

Despite its strengths, the Multi Mortar has some notable weaknesses. It struggles against high-hitpoint troops that can absorb its attacks, allowing support units to survive longer. It also has a blind spot, meaning nearby troops can avoid its attacks entirely if they get too close. This makes it vulnerable to aggressive strategies that quickly close the gap between the Multi Mortar and attacking units.

To mitigate these weaknesses, pairing the Multi Mortar with defenses that complement its capabilities is essential. Placing a Crusher nearby helps counter its inability to hit close-range enemies, ensuring that tanky ground troops are dealt with effectively. However, both defenses lack the ability to target air troops, so additional anti-air defenses like Firecrackers or Air Bombs should be placed nearby to prevent aerial units from exploiting this weakness.

Offensive Strategies

Air units are the best way to counter the Multi Mortar, as it exclusively targets ground troops. Beta Minions and Drop Ships can attack without fear of being damaged, making them effective choices when planning an air-based assault.

Drop Ships, while not directly threatened by the Multi Mortar, deploy Skeletons that can be eliminated by its splash damage if they are not too close. Keeping Drop Ships positioned strategically ensures that their Skeletons land safely without being wiped out immediately.

Using high-hitpoint tanks like Boxer Giants or the Battle Machine is another effective strategy. These units can absorb Multi Mortar shots while other troops move in to deal damage. However, attackers must ensure that their tanks remain at a distance where the Multi Mortar can still fire at them. If the tanks enter its blind spot, the Multi Mortar will stop attacking them and instead focus on other vulnerable troops.

Another way to neutralize the Multi Mortar is by getting troops into its minimum range as quickly as possible. Once inside this range, the Multi Mortar becomes ineffective, allowing units like Raged Barbarians or Sneaky Archers to destroy it without taking damage.

To minimize the impact of the Multi Mortar’s splash damage, deploying troops in a spread-out formation is essential. This prevents multiple units from being hit by the same volley, reducing overall damage and ensuring more troops survive to continue the attack.

Base Design Considerations

The Multi Mortar’s effectiveness is heavily influenced by its placement within your base layout. Since it has a long attack range but a blind spot, positioning it properly ensures it provides maximum coverage while minimizing its vulnerability.

A centralized placement is often the best approach, as it allows the Multi Mortar to cover a large portion of the base. This makes it difficult for attackers to reach it early in the battle, forcing them to deal with other defenses before they can take it down. Keeping it near key structures like the Builder Hall or Firecrackers also ensures it remains protected from air troops and ground-based distractions.

Placing the Multi Mortar too close to the outer walls is a common mistake. Bombers can easily target and destroy walls, allowing enemy troops to breach the base and take down the Multi Mortar before it can deal significant damage. Instead, it’s best to keep it at least a few tiles away from the outer walls, ensuring that enemies have to work through multiple defenses before reaching it.

Another important consideration is funneling. Since the Multi Mortar is particularly effective against groups of small troops, designing your base so that enemy units naturally group together in its attack range will increase its impact. Pairing it with structures like Crushers and Guard Posts can help force enemy troops into tight spaces where the Multi Mortar can maximize its splash damage.

More Defensive Synergies

The Multi Mortar works best when paired with defenses that compensate for its weaknesses, particularly its inability to target air troops and nearby ground units.

Crusher Synergy:

The Crusher is one of the best defenses for stopping tanky ground units in their tracks, making it an ideal pairing with the Multi Mortar. Since the Multi Mortar is vulnerable to close-range attacks due to its blind spot, placing a Crusher nearby can prevent enemy troops from reaching it too easily. However, both defenses share a significant weakness—they cannot target air troops. To ensure the Multi Mortar remains protected from aerial assaults, supporting it with anti-air defenses is necessary.

Firecrackers and Air Bombs:

Firecrackers and Air Bombs provide a strong defensive combination alongside the Multi Mortar. Since the Multi Mortar can only target ground units, it becomes an easy target for Beta Minions and Drop Ships if left unprotected. Placing Firecrackers or Air Bombs nearby ensures that even if enemy ground troops are neutralized, aerial units will not be able to destroy the Multi Mortar without resistance. This setup helps maintain a balanced defense against both ground and air threats.

Guard Post Support:

Guard Post troops serve as an additional layer of defense by acting as distractions for enemy attackers. When placed strategically, they can disrupt the enemy’s attack plan and force troops like Cannon Carts to target them instead of the Multi Mortar. This delay allows the Multi Mortar to continue firing at incoming units, increasing its effectiveness in dealing damage over time. The Guard Post can also help disrupt funneling strategies, making it harder for opponents to direct their troops efficiently.

Traps for Crowd Control:

Traps like Mines and Mega Mines work well in conjunction with the Multi Mortar by softening up enemy troops before they enter its attack range. Since the Multi Mortar fires multiple shells per volley, weakened troops are more likely to be eliminated before they can deal significant damage. Placing these traps near common attack entry points increases the likelihood of damaging enemy forces before they reach key defenses.

Double Cannon for Focused Damage:

While the Multi Mortar excels at splash damage, it lacks high single-target damage, which makes it less effective against high-hitpoint units like the Battle Machine and Boxer Giants. Pairing it with a Double Cannon helps compensate for this weakness. The Double Cannon delivers focused, high-damage shots that can take down tanky units much faster, complementing the Multi Mortar’s role in dealing with groups of smaller troops. This combination ensures that both swarms and high-hitpoint units are accounted for, making it harder for attackers to break through the base.

Builder Hall Level-Specific Usage

The Multi Mortar’s importance evolves as players progress through Builder Hall levels, with different strategies being required at each stage.

Builder Hall 5-6:

At Builder Hall 5 and 6, the Multi Mortar becomes a crucial defense against mass attacks using Sneaky Archers and Raged Barbarians. Since these troops rely on swarming tactics, the Multi Mortar’s splash damage is highly effective at cutting down large groups before they can reach important structures. However, because players have fewer defenses available at this stage, proper placement is essential. Positioning it near the center of the base ensures that it remains protected while still covering as much of the base as possible. Attackers will often try to take it out early using Sneaky Archers or Bombers, so placing it too close to the edge of the base can make it an easy target.

Builder Hall 7-8:

At Builder Hall 7 and 8, stronger tank units like the Battle Machine and Boxer Giants become more common. While the Multi Mortar still counters swarms effectively, its role shifts toward softening up tanks before they reach Crushers or Double Cannons. The splash damage helps weaken Boxer Giants, making it easier for other defenses to eliminate them before they deal too much damage. By Builder Hall 8, the Multi Mortar also gains additional importance due to the gearing-up feature, allowing players to upgrade a Home Village Mortar to fire in bursts. This increases its overall value, making it an essential structure to protect in both the Builder Base and the Home Village.

Builder Hall 9-10:

At Builder Hall 9 and 10, attackers frequently use a combination of air and ground units, requiring a more balanced defensive setup. While the Multi Mortar remains effective against ground troops, it must be paired with strong anti-air defenses like Air Bombs and Firecrackers to prevent Beta Minions and Drop Ships from exploiting its inability to target air units. Additionally, Cannon Carts and Night Witches become more common, making it important to position the Multi Mortar where it can continuously hit these units without being taken out too early. A well-protected Multi Mortar can significantly weaken an opponent’s attack, ensuring that other defenses can finish off the remaining troops.

Gearing Up in the Home Village

At Builder Hall 8, players gain the ability to gear up a Mortar in their Home Village, transforming it into a Multi Mortar variant that fires in bursts instead of single shots. This upgrade allows the Home Village Mortar to function similarly to its Builder Base counterpart, making it more effective against groups of attacking troops.

Pros of Gearing Up:

Gearing up the Mortar in the Home Village provides several advantages, particularly against swarms of low-hitpoint units. The burst-fire mechanic allows it to deal more damage per volley, making it highly effective against Barbarians, Archers, and Goblins. This increased coverage ensures that large groups of troops are hit harder, reducing their chances of overwhelming defenses. Additionally, the geared-up Mortar can help counter spam-based attacks in the Home Village, such as mass Hog Riders or Balloons. By dealing splash damage in multiple shots, it can weaken or eliminate groups of units before they reach key defenses.

Cons of Gearing Up:

However, gearing up also comes with drawbacks. One of the main disadvantages is the longer reload time between volleys. While the burst-fire mode increases damage output in a short time, the delay between attacks makes it less effective against slow, tanky units that can absorb the initial shots and continue advancing. This means high-hitpoint troops like Golems, P.E.K.K.As, or Electro Titans are less affected by the geared-up Mortar. Another limitation is that the geared-up Mortar cannot be used in the Clan Capital or War Bases, restricting its strategic flexibility. Since it only applies to the Home Village, players must consider whether the gearing-up process is worth the trade-offs based on their defensive needs.

Players should carefully consider their base’s defensive needs before gearing up a Mortar. If the base relies on quick, high-damage single shots for eliminating strong troops, the standard Mortar may be the better choice. However, if swarm attacks are a frequent problem, the Multi Mortar’s burst capability can be a valuable addition.

Common Mistakes to Avoid

Even though the Multi Mortar is a strong defense, improper placement or misjudged defensive setups can render it ineffective. Here are some common mistakes to avoid:

Placing the Multi Mortar too close to walls can make it an easy target for Bombers. Since Bombers have the ability to destroy walls and hit defenses behind them, a poorly positioned Multi Mortar can be eliminated without putting up much resistance. To avoid this, it should be placed deeper inside the base, ensuring it remains protected from long-range attacks. Keeping it away from exposed walls also prevents attackers from easily creating an opening that leads directly to it.

Leaving the Multi Mortar unprotected is another critical mistake. Since it cannot attack air troops or nearby ground units, it is vulnerable if left alone. Surrounding it with defenses like Crushers, Firecrackers, and Guard Posts helps cover its weaknesses. Crushers deal with tanky ground units that get too close, Firecrackers counter air units that would otherwise take advantage of its inability to hit them, and Guard Post troops serve as distractions, buying time for the Multi Mortar to deal damage.

Grouping the Multi Mortar with other high-priority defenses can backfire if attackers can take them all out in a single push. Placing it too close to key structures like the Mega Tesla or Roaster allows opponents to focus their attack on one area and eliminate multiple defenses at once. Spreading out these important buildings makes it harder for attackers to destroy them in a single wave, forcing them to commit more resources and time.

Ignoring the Multi Mortar’s blind spot can be a costly oversight. Skilled attackers can use this weakness to their advantage by getting troops inside its minimum range, making it completely ineffective. Placing a Crusher or Guard Post nearby can help mitigate this issue. Crushers prevent tanky units from lingering too close, while Guard Post troops distract and stall enemy forces before they reach the Multi Mortar’s blind spot.

Failing to adjust the Multi Mortar’s placement as Builder Hall levels increase can also reduce its effectiveness. As new attacking strategies emerge and different troops become more common, a placement that worked well at Builder Hall 5 may not be as effective at Builder Hall 9 or 10. Regularly evaluating its position based on evolving threats ensures that it remains a valuable defensive asset rather than an easy target.

By avoiding these common mistakes and optimizing its placement, players can ensure that their Multi Mortar remains a key defensive structure in their Builder Base.
