Clan War Leagues

Clan War Leagues (CWL) offer a more intense, structured competitive experience compared to regular Clan Wars. Instead of a single war, clans battle it out over a full week in a league format, striving for promotion and valuable League Medals. This guide will equip you with everything you need to know to excel in CWL, from sign-up to advanced strategies and reward optimization.

Joining a Clan War League

To participate, your clan leader or co-leader must sign up the clan during the designated sign-up period, which typically lasts for two days at the beginning of each month. The minimum number of participants required is 15 players, but clans can register with up to 50 members. The more members registered, the more flexibility your leaders have in rotating players throughout the week, ensuring more players receive rewards.

Sign-Up Process & Requirements

  • Sign-up Location: Navigate to the Clan War Leagues tab within the Clan War screen. This tab becomes active during the sign-up window.
  • Registration Size: Clan leaders must choose between a 15v15 or 30v30 league. This decision impacts the number of players who can attack daily and the overall strategy for roster management. A 15v15 league is often preferred by clans with fewer active high-level players, while 30v30 allows for broader participation.
  • Player Roster: Add all eligible clan members to the roster. Players must have a Town Hall 6 or higher to participate. It's crucial to include all active players who might participate, as only those on the initial roster can be rotated into battles.
  • Eligibility: Only players with Town Hall 6 or above can be added to the CWL roster. Lower Town Hall levels are automatically excluded.

The League Week Structure

Once signed up, your clan will be matched with 7 other clans of similar league standing. The league week consists of 7 consecutive war days, with one attack per player per day. Unlike regular wars, there are no preparation days between battles, making efficient planning and communication vital.

Daily War Flow: A Step-by-Step Breakdown

  1. Matchmaking (Day 1): At the start of the CWL week, your clan is placed into a group with 7 other clans. Your first opponent is revealed.
  2. Preparation Phase (23 hours):
    • This phase begins immediately after matchmaking or the previous battle day ends.
    • Scouting: diligently scout opponent bases to identify weaknesses, trap placements, and Clan Castle troop compositions.
    • Army Planning: Based on scouting, players finalize their army compositions and spell loadouts.
    • Clan Castle Requests: Players request specific defensive troops for their Clan Castles. Leaders and co-leaders should ensure these are filled promptly with strong, high-level troops (e.g., Electro Dragons, Golems, Lava Hounds, Super Minions).
  3. Battle Day (24 hours):
    • This is the active attack phase. Each participating player gets one attack.
    • Strategic Attacks: Players execute their planned attacks. Communication within the clan is key to avoid over-attacking low-value targets or leaving high-value targets unattacked.
    • Star Collection: The primary goal is to maximize stars. Two-star attacks on higher Town Hall levels and three-star attacks on lower Town Hall levels are crucial for victory.
  4. Results & Next Match: After Battle Day concludes, results are tallied, and the next opponent is revealed, initiating the next 23-hour preparation phase. This cycle repeats for 7 days.

Strategies for Success in Clan War Leagues

Roster Management: Maximizing Medals and Performance

Effective roster management is crucial, especially in larger leagues (30v30). Clan leaders should consider rotating players to ensure everyone gets a chance to earn stars and League Medals. Players who don't participate in a battle day can still be swapped in for subsequent days.

  • Maximizing Medals: To receive the full share of League Medals, a player must earn at least 8 stars over the course of the entire CWL week. Leaders should strategically rotate players to ensure as many members as possible reach this threshold.
  • Strategic Swaps:
    • If a player is struggling with a difficult matchup, consider benching them for a day and bringing in a fresh attacker who might have a better chance.
    • Rotate lower Town Hall players in for easier matchups to help them secure stars and contribute.
    • Ensure that players who are consistently performing well are given opportunities to attack.
  • Bench Management: The initial roster can be up to 50 players, but only 15 or 30 can participate daily. The "bench" allows leaders to swap players in and out. This is vital for managing player availability and ensuring everyone gets a chance to earn stars.

Attack Planning: Every Star Counts

With only one attack per player, every star counts. Communication and strategic targeting are paramount. Clan chat and external communication tools (like Discord) are invaluable for coordinating attacks.

  • Target Selection:
    • High-Value Targets: Focus on securing 2-star attacks on higher Town Hall levels (e.g., a TH14 attacking a TH15) to guarantee stars against tough opponents.
    • Three-Star Opportunities: Prioritize 3-star attacks on lower Town Hall levels (e.g., a TH14 attacking a TH13) to maximize star difference.
    • Avoid "Sniping": Unless absolutely necessary to secure a win or prevent a loss by a single star, avoid attacking for only 1 star. Every attack should aim for at least 2 stars, ideally 3.
    • Clean-up Attacks: If a base was previously attacked for 1 or 2 stars, a stronger attacker might be assigned to "clean up" and secure the remaining stars.
  • Clan Castle Troops (Offensive): Always request and fill your offensive Clan Castle with strong, appropriate troops for your army composition. For example, Balloons for LavaLoon attacks, Yetis for Yeti Smash, or Hog Riders for Hybrid attacks.
  • Army Composition: Tailor your army to the specific base you are attacking. Don't be afraid to use expensive armies, as the rewards (League Medals) are significant.
    • Popular CWL Compositions:
      • Lalo (Lava Hound and Balloons): A potent air attack, especially effective against single-target Inferno Towers and spread-out air defenses. Often paired with Minions, Haste spells, and Rage spells.
      • Hybrid (Hog Riders and Miners): A powerful ground attack that can funnel through bases. Requires careful funneling and healing spell placement. Often uses Grand Warden's Eternal Tome ability strategically.
      • Yeti Smash (Yetis and Witches/Bowlers): A strong ground push, particularly effective against compact bases. Yetimites provide excellent splash damage. Often supported by Log Launchers or Wall Wreckers.
      • Electro Dragon Spam: While sometimes less consistent for 3-stars at higher levels, it's a reliable 2-star strategy for many players due to its ease of use and chain lightning ability.
      • Super Bowler Smash: A ground attack utilizing Super Bowlers' bouncing attacks to clear defenses. Effective against bases with clustered defenses.
    • Spell Loadout: Adjust your spells based on the base. Jump spells for walls, Freeze for Inferno Towers, Rage for damage, Heal for ground troops, Haste for air troops.

Defense: Protecting Your Stars

While you only get one attack, your defensive layout is active for all 7 wars. A strong defensive base can prevent opponents from securing easy stars, which directly impacts your clan's overall performance and star difference.

  • Anti-3 Star Layouts: Prioritize base designs that are difficult to 3-star, even if they are susceptible to 2-star attacks. Spreading out key defenses, creating dead zones, and protecting the Town Hall are common strategies.
  • Strategic Trap Placement:
    • Air Bombs and Seeking Air Mines: Place these to counter air attacks, especially targeting Lava Hounds, Balloons, and Electro Dragons.
    • Giant Bombs and Spring Traps: Position these to disrupt ground pushes, targeting Hog Riders, Miners, and Valkyries.
    • Skeleton Traps: Set to air or ground depending on common attack strategies in your league.
  • Clan Castle Troops (Defensive): Ensure your Clan Castle is always filled with high-level defensive troops. Electro Dragons, Super Minions, Golems, Lava Hounds, and Witches are excellent choices for their high health, damage, or disruptive abilities.
  • Hero Placement: Ensure your Heroes are strategically placed to defend key areas and not easily lured or taken down early.

Rewards: League Medals and the League Shop

League Medals are the primary reward for participating in Clan War Leagues. The number of medals you receive depends on your clan's league, your individual star performance, and whether your clan wins or loses. These medals can be spent in the League Shop to significantly accelerate your base progression.

League Shop Items: Accelerate Your Progress

The League Shop offers exclusive and highly valuable items that can drastically reduce upgrade times and resource costs:

  • Hammers: These are the most coveted items, instantly completing an upgrade without consuming resources or time.
    • Hammer of Fighting: Instantly upgrades any troop to the next level.
    • Hammer of Building: Instantly upgrades any building to the next level.
    • Hammer of Spells: Instantly upgrades any spell to the next level.
    • Hammer of Heroes: Instantly upgrades any hero to the next level.
  • Potions: These items speed up various aspects of your game.
    • Research Potions: Speeds up laboratory research by 24x for 1 hour.
    • Builder Potions: Speeds up all active builder construction by 10x for 1 hour.
  • Wall Rings: Used to instantly upgrade walls without needing gold or elixir. The number of rings required per wall segment varies by wall level.

Bonus Medals: Rewarding Top Performers

  • Distribution: Clan leaders can distribute bonus League Medals to top-performing members at the end of the CWL week. The number of bonuses available increases with your clan's league (e.g., Crystal League II might offer 5 bonuses, while Champion League I might offer 10).
  • Criteria: Leaders typically award bonuses based on factors like total stars earned, attack efficiency (high 3-star rate), defensive performance, and overall participation/communication.
  • Impact: These bonuses are a significant boost to individual medal counts and are a great way to recognize and reward dedicated players.

Common Pitfalls and How to Avoid Them

  • Forgetting to Attack: With only one attack per day, missing an attack is a huge detriment to your clan's performance. Set reminders!
  • Poor Target Selection: Attacking a base that is too strong for you, or attacking a base that a weaker clanmate could easily 3-star, can waste attacks. Coordinate targets.
  • Empty Clan Castles: Going into battle with an empty offensive Clan Castle or having empty defensive Clan Castles is a critical mistake. Always ensure they are filled.
  • Lack of Communication: Without proper communication, attacks can be duplicated, or difficult bases can be left unattacked. Use clan chat or external tools for coordination.
  • Ignoring Base Layouts: Using a "one-size-fits-all" army composition without scouting the base will lead to inconsistent results. Tailor your army.

Participating in Clan War Leagues is an excellent way to earn valuable resources and accelerate your base progression. Coordinate with your clan, plan your attacks wisely, and strive for those coveted promotion spots to climb the league ranks and earn even greater rewards!
