Clash of Clans: How to 3-Star the Portal Challenge

To clear the Portal Challenge in Clash of Clans with three stars, funnel your main strike team into the Grand Warden's aura, activate his Portal Pendant to teleport directly into the core, and immediately protect the landing with spell coverage.

The event army highlights the Grand Warden’s Portal Pendant equipment, which transports the Warden and nearby troops straight across defensive walls to a designated exit point. Triggering this ability too early leaves units stranded outside, so pathing and timing determine whether the attack succeeds.

Attack Phase	Objective	Key Units & Spells
1. Funnel	Clear outer trash to direct pathing inward	Baby Dragon, Sneaky Goblins, Barbarian King
2. Core Entry	Teleport the central strike team across walls	Grand Warden (Portal Pendant), Rage Spell
3. Core Control	Suppress high-damage defenses and reinforcements	Freeze Spells, Poison Spell
4. Cleanup	Clear bypassed defenses and outer structures	Royal Champion, Minions, Archers

Step 1: Establish the Outer Funnel

Do not drop your entire army at once. The outer perimeter features resource collectors, cannons, and archer towers that can pull your frontline away from the Warden's entry line.

Deploy edge-clearing units, such as a Baby Dragon or Sneaky Goblins, on the outer corners flanking your intended entry angle.
Send the Barbarian King down one perimeter edge to clear an exterior compartment.
Wait until both edges are trimmed before deploying the primary ground units, ensuring they walk straight toward the Warden rather than circling the base perimeter.

Step 2: Teleport Into the Core

Once the funnel holds, deploy your heavy ground troops behind the entry point so they step into the Grand Warden's Life Aura circle.

Watch the troop grouping closely. Allow your heavy frontline and damage dealers to gather around the Warden.
Activate the Grand Warden's ability as the squad clusters together. The Portal Pendant transports the Warden and all nearby allies through the gateway and directly into the core defensive cluster.
Drop a Rage Spell over the exit portal location immediately. Your units need the immediate boost in damage and attack speed to destroy surrounding defenses before incoming fire stacks up.

Step 3: Neutralize Core Threats and Reinforcements

Materializing in the core triggers the enemy Clan Castle and brings your army into range of high-damage defenses.

Defensive Clan Castle Troops: Cast your Poison Spell directly over enemy reinforcements as they approach your heroes to cut their attack speed and movement.
Monolith and Town Hall: Drop your first Freeze Spell on the Monolith or the Town Hall's weapon system as soon as your units take target lock.
Single-Target Inferno Towers: Use subsequent Freeze Spells if an Inferno beam ramps up on the Barbarian King or Grand Warden. Avoid spending Freeze Spells on low-threat perimeter defenses.

Step 4: Deploy the Royal Champion for Flank Cleanup

With the base core broken, turn your attention to the bypassed outer defenses and remaining trash buildings.

Deploy the Royal Champion on a flanking angle to target isolated defenses, such as Mortars and Archer Towers, that were skipped by the portal teleport.
Activate her Shield ability to take down grouped perimeter defenses.
Distribute remaining cleanup units, including Archers and Minions, behind the cleared sectors to finish off peripheral storages and prevent a time-fail.
