Mortars Mastery: Splash Damage Secrets for Stopping Mass Troop Waves

Introduction

Picture this: your base is under siege, a tidal wave of Barbarians and Archers surges across your walls, and it looks like your resources are about to be pillaged—unless your defenses can turn the tide. What’s the unsung hero in this scenario? The Mortar. While often overshadowed by flashier defenses, Mortars wield a unique power: devastating splash damage that can obliterate swarms of low-HP troops in seconds. But are you truly harnessing their full potential, or are you leaving your base vulnerable to mass attacks? Let’s uncover the secrets behind Mortar mastery and learn how to make every shot count.

Why Mortars Matter: The Splash Damage Advantage

Mortars are specialized for one thing: area-of-effect (AoE) damage. Unlike Cannons or Archer Towers, which target one unit at a time, Mortars launch explosive shells that deal damage to all troops within a radius. This makes them especially effective against "spam" tactics—mass deployments of Barbarians, Archers, Goblins, or even Skeletons from spells.

The Numbers Behind the Boom

• Damage per shot: High for its level, but with a slow fire rate.
• Splash radius: Typically 4 tiles, large enough to hit clustered troops.
• Range: 4–11 tiles, covering a wide area but unable to hit troops too close.
• Targeting: Ground units only, making Mortars vulnerable to air raids but lethal against ground swarms.

Example:

A level 8 Mortar deals 44 DPS (damage per second) but, given its slow fire rate, can wipe out an entire group of Archers or Barbarians in a single hit.

Mortar Placement: The Art of Strategic Positioning

Centralization is Key

Mortars have a minimum range, meaning they can’t hit enemies right next to them. To maximize coverage and minimize blind spots:

• Place Mortars near the center of your base.
• Avoid clustering them together—spread them out to prevent all being destroyed by a single spell (e.g., Lightning or Earthquake).

Overlapping Fields of Fire

The most effective bases ensure that Mortar coverage overlaps. This way, if one Mortar is being upgraded or destroyed, others can still protect vulnerable areas.

Pro Tip:

Use a triangular or diamond formation for three Mortars. This provides overlapping coverage for the majority of your base and is especially effective at Town Hall 7–9.

Timing and Targeting: Understanding Mortar Mechanics

Slow but Deadly

Mortars have a slow reload time (5 seconds per shot), so timing is everything. If attackers spread their troops, Mortars may waste shots on single units. But against tightly packed waves, their value skyrockets.

Countering Barch (Barbarian + Archer) Attacks

• Wait for clustering: Most attackers drop Barbarians as a shield, then Archers behind. Mortars target the Barbarians first, but the real payoff comes when Archers bunch up.
• Predictive targeting: Mortars fire where troops are, not where they’re going. Smart attackers will try to "walk" their troops through Mortar fire. Layering defenses (walls, traps) can slow troops and keep them in the danger zone.

Synergy with Other Defenses

Mortars and Bomb Towers: The Anti-Swarm Duo

Bomb Towers also deal splash damage but have a shorter range and a death explosion. Placing Bomb Towers near Mortars covers both the Mortar’s blind spot and provides a second layer of splash damage.

Mortars and Spring Traps

Spring Traps are perfect for thinning out the survivors of a Mortar volley, especially against Hog Riders or Giants. Place Spring Traps along common attack paths leading into Mortar coverage.

Complementing with Walls and Funnels

Walls force attackers to bunch up—precisely what Mortars need. Create funnels that channel troops into kill zones covered by Mortars.

Mortars vs. Spells: Surviving the Lightning

One of the biggest threats to Mortars is the Lightning Spell. At lower Town Hall levels, attackers love to zap Mortars out of existence before sending in their mass troops. How do you counter this?

• Spread out your Mortars: Never place two Mortars close enough to be hit by the same spell.
• Upgrade strategically: Higher-level Mortars can survive more spell damage, forcing attackers to use more spells for the same effect.
• Bait and switch: Place a high-value resource building near a Mortar to tempt attackers to use their spells elsewhere.

Mortars Through the Town Hall Levels: When and How to Upgrade

Early Game (TH5–TH7)

Mortars are your main defense against mass ground attacks. Prioritize upgrading them early, as their splash damage is unmatched at these levels.

Mid Game (TH8–TH10)

While new defenses like Bomb Towers and Wizard Towers enter the scene, Mortars remain crucial for anti-swarm defense. Overlapping coverage and synergy with other splash defenses become more important.

Late Game (TH11+)

Mortars become less dominant as high-HP troops and air attacks take center stage. However, they still play a vital role in deterring spam attacks and supporting core defenses.

Player Insight:

"I underestimated Mortars at TH10, focusing on X-Bows and Infernos. After a string of Barch raids, I upgraded my Mortars and immediately saw a drop in resource losses." — Clan Leader, Crystal League

Common Mistakes and How to Avoid Them

1. Placing Mortars too close to the edge: Easy targets for Giants and Hog Riders.
2. Clustering Mortars: Vulnerable to spells.
3. Neglecting upgrades: Underleveled Mortars are easily destroyed or ignored by attackers.
4. Ignoring synergy: Mortars work best when paired with other splash and single-target defenses.

Advanced Tips: Outwitting the Mass Attacker

• Dummy Defenses: Place a low-level defense near a Mortar to bait spells.
• Trap Integration: Use Giant Bombs and Spring Traps in Mortar kill zones for devastating combo damage.
• Upgrade Timing: Upgrade Mortars one at a time to maintain splash coverage during wars.
• Adapt to Meta: Watch replays. If mass air attacks are trending, focus on Air Defenses, but don’t neglect Mortars for ground spam.

Conclusion: The Mortar’s True Power

Mortars may not grab headlines like Inferno Towers or Eagle Artillery, but their ability to annihilate mass troop waves makes them indispensable—especially for defending your resources and maintaining trophy count in lower and mid-level play. Mastering Mortar placement, timing, and synergy with other defenses is a skill that rewards you with fewer losses and more successful defenses.

Take action: Review your base layout, upgrade those Mortars, and watch as enemy swarms are reduced to rubble. In Clash of Clans, it’s not always the flashiest weapon that wins—it’s the one that’s used wisely. Will your Mortars be up to the challenge?
