Clash of Clans Line Deployment 3-Star Attack Guide

To execute a line deployment attack in Clash of Clans, clear the outer perimeter corners with anchor units, drag your primary army evenly across a flat base edge, and activate the Grand Warden's Eternal Tome once your troops push into core defenses. This broad-front assault overwhelms point defenses and avoids the trap concentrations that punish narrow funnels.

Identifying the Entry Angle

A line deployment requires a flat side of the enemy base rather than a sharp corner. Deploying directly onto a corner splits your army into two divergent groups that walk along opposite outer edges, leaving the core untouched.

When planning your entry:

• Target flat boundaries: Pushing parallel to a flat wall ensures your frontline shares incoming fire evenly and keeps trailing support units concentrated.
• Avoid opposing Air Sweepers: When deploying air or hybrid armies, angle your attack so Air Sweepers push across the line sideways or are quickly destroyed by initial perimeter units.
• Account for deep core defenses: Align your push so massive area-of-effect targets—such as the Town Hall, Monolith, and Multi-Target Inferno towers—are encountered during the midpoint of the attack rather than all at once on entry.
• Watch for moats: Do not enter from a side featuring wide dead zones or segmented outer trash rings that pull heavy units horizontally.

Deployment Order and Timing

Executing a successful line deployment requires dropping units in rapid, distinct stages across a wide front rather than tapping everything on a single tile.

Slide one or two fingers steadily along the chosen map boundary to create a uniform line. Dropping heroes approximately two seconds behind the main frontline prevents them from outpacing tanks while keeping them close enough to benefit from aura abilities and spell coverage.

Timing the Grand Warden's Eternal Tome

The Grand Warden's Eternal Tome is the central survivability tool of a wide-line push. Because your troops trigger multiple defensive buildings simultaneously, an early or late activation will ruin the attack.

Do not trigger the Eternal Tome immediately upon deployment. Perimeter defenses and exterior trash buildings deal moderate single-target damage that your main tanks can absorb without protection.

Hold the ability until your frontline breaches the first interior wall compartment and enters the attack radius of heavy core threats. Trigger Eternal Tome when your troops face incoming Eagle Artillery barrages, Scattershot volleys, or the Town Hall's Giga Inferno. This brief invulnerability keeps both the frontline tanks and following heroes alive through the base's highest-damage zone.

Core Spell Management

Spells must clear resistance bottlenecks and maintain inward forward momentum:

• Rage Spells: Drop Rage Spells proactively slightly ahead of your main force as it enters dense central compartments, pulling units forward at high speed.
• Freeze Spells: Target single-target Inferno Towers that lock onto heroes, or freeze active Monoliths targeting your primary tanks.
• Poison Spells: Drop Poison directly over defending Clan Castle reinforcements or clustered enemy heroes, pairing it with a Rage Spell so your ranged troops eliminate them quickly.
• Overgrowth Spells: If an awkward off-center compartment threatens to pull your troops away from the Town Hall path, cast Overgrowth on that pocket to temporarily disable it and force your units to stay on a straight trajectory.

Preventing Flank Drift and Securing the Three-Star

Wide deployments often struggle in the final thirty seconds if troops disperse outward and leave corner structures standing.

Hold two or three cleanup units—such as Wizards, Minions, or Baby Dragons—in reserve during the opening assault. Once the center of the base collapses, deploy these reserves on cleared outer perimeter pockets to clean up remaining resource storages. Delay triggering your Barbarian King and Royal Champion abilities until the final phase of the attack to provide the speed and health recovery needed to wipe out the remaining defensive quadrant.
