Clash of Clans Clan War Basics: Everything You Need to Know

Clan Wars are a cornerstone of the Clash of Clans experience. They offer a thrilling blend of strategic planning, coordinated teamwork, and individual skill, rewarding clans with loot, experience, and bragging rights. This comprehensive guide will break down every aspect of Clan Wars, from the fundamental mechanics to advanced strategies, ensuring you have the knowledge to become a valuable asset to your clan and a formidable opponent in war.

Part 1: Understanding the Core Mechanics

1.1 What is a Clan War?

A Clan War is a 48-hour event where two clans of similar strength are pitted against each other. The event is divided into two distinct phases:

  • Preparation Day (24 hours): This is the strategic planning phase. Clan members donate troops to each other’s War Clan Castles, scout enemy bases, and discuss attack strategies. No attacks can be launched during this phase.
  • Battle Day (24 hours): This is the combat phase. Each clan member gets two attacks to use against the enemy clan’s bases. The goal is to earn stars by destroying buildings, with a perfect attack earning three stars. The clan with the most stars at the end of Battle Day wins the war.

1.2 War Matchmaking: How Clans are Paired

Clash of Clans uses a matchmaking system that attempts to pair clans with similar offensive and defensive strength. The primary factors influencing matchmaking are:

  • War Weight: This is a hidden value assigned to each player based on their offensive and defensive capabilities. It’s calculated by considering the levels of their troops, heroes, spells, defenses, and walls. Higher-level buildings and troops contribute more to war weight.
  • Town Hall Levels: While not the only factor, Town Hall levels play a significant role. The system tries to balance the number of Town Halls at each level within the participating clans.
  • Clan War League Rank (for CWL): In Clan War Leagues (explained later), your clan’s current league rank is the primary matchmaking factor. You’ll face other clans in the same league.
  • Recent War Performance Although the exact weighting is unknown, the game does account for a clan’s recent win/loss record.

Important Note on War Weight: Engineering (intentionally keeping defenses low while maxing offense) used to be a significant advantage. Supercell has implemented changes over the years to make engineering less effective, and now a more balanced approach to base progression is generally recommended.

1.3 Opting In and Out of War

  • Individual Participation: Each player can choose to opt in or out of Clan Wars. This is done through the player’s profile, under the “My Profile” tab. A green shield indicates participation, while a red shield indicates opting out. It’s crucial to opt out if you know you won’t be able to make both attacks, as missing attacks severely hurts your clan’s chances of winning.
  • Clan Leader/Co-leader Control: Clan Leaders and Co-leaders have the authority to include or exclude members from war, even if those members have opted in. This is often used to ensure a balanced war lineup or to remove inactive players.
  • Minimum Participants: A clan needs at least 10 members opted in to start a war. Wars can be 10v10, 15v15, 20v20, 25v25, 30v30, 35v35, 40v40, or 50v50.

1.4 War Bases vs. Home Village

A key concept to understand is the difference between your Home Village and your War Base:

  • Home Village: This is your regular base that gets attacked in multiplayer battles. It’s where you collect resources, train troops, and upgrade your buildings.
  • War Base: This is a separate layout specifically designed for Clan Wars. It does not affect your Home Village resources or defenses. You can design your War Base to be completely different from your Home Village, optimizing it for defense against war attacks. Changes made to your War Base do not reflect in your Home Village, and vice versa.

Why the separation? This allows you to create specialized defensive layouts for war without jeopardizing your resource protection in your Home Village. It also prevents enemies from practicing attacks on your active base.

1.5 War Loot and Rewards

Winning a Clan War provides significant rewards:

  • War Win Bonus: This is a large amount of Gold, Elixir, and Dark Elixir awarded to each participating member of the winning clan. The amount of the bonus depends on the strength of the enemy bases you successfully attack.
  • Partial Bonus for Draws: If the war ends in a tie, both clans receive a smaller bonus (around 40% of the win bonus).
  • Partial Bonus for Losses: Even if your clan loses, you still receive a small bonus (around 30% of the win bonus) based on your successful attacks.
  • Clan XP: Winning wars earns Clan XP, which contributes to the clan’s level. Higher clan levels unlock various perks, such as increased troop donation limits, donation refunds, and war bonus loot increases.

Important Note: You only receive the War Win Bonus for attacks where you earn at least one star. A failed attack (zero stars) yields no bonus loot, even if your clan wins the war.

Part 2: Preparation Day – Strategy and Coordination

Preparation Day is just as crucial as Battle Day. A well-coordinated clan will use this time effectively to maximize their chances of victory.

2.1 Scouting Enemy Bases

  • Analyze Town Hall Levels: Quickly identify the range of Town Hall levels in the enemy clan. This will give you a general idea of their overall strength.
  • Check War Base Layouts: Carefully examine each enemy War Base. Look for weaknesses, such as:
    • Exposed Air Defenses: Vulnerable to air attacks like LavaLoon or Dragon attacks.
    • Centralized Clan Castle: Easier to lure and eliminate the Clan Castle troops.
    • Weak Walls: Susceptible to ground attacks like GoWiPe or Hog Riders.
    • Predictable Trap Placement: Look for common trap locations (Giant Bombs, Spring Traps) to anticipate and avoid them.
    • Poor Hero Placement: Heroes that are easily lured or isolated can be taken down early in the attack.
    • Inferno Tower Mode: Single or Multi-target. Multi-target is much less effective against high HP troops.
    • Eagle Artillery Placement: How exposed is it?
  • Note Clan Castle Capacity: The Clan Castle level determines how many troops it can hold. This is crucial for planning your attack strategy, as you’ll need to account for those defending troops.

2.2 War Base Design Principles

A strong War Base is essential for defending against enemy attacks. Here are some key principles to consider:

  • Anti-3-Star Design: The primary goal is to prevent the enemy from getting three stars. It’s better to force a two-star attack than to risk a three-star.
  • Spread Out Defenses: Avoid clumping all your defenses together. This makes your base vulnerable to splash damage attacks (like Wizards and Dragons).
  • Protect Key Defenses: Your most important defenses (Inferno Towers, Eagle Artillery, X-Bows, Air Defenses) should be well-protected and difficult to reach.
  • Compartmentalization: Use walls to create separate compartments within your base. This forces attackers to break through multiple layers of walls, slowing them down and exposing them to defenses.
  • Trap Placement: Place traps strategically to maximize their effectiveness.
    • Giant Bombs: Place them where Hog Riders or other ground troops are likely to path. Double Giant Bombs (placed next to each other) can instantly kill a group of Hog Riders.
    • Spring Traps: Place them between defenses to fling ground troops away.
    • Seeking Air Mines: Place them near Air Defenses to target Lava Hounds or Healers.
    • Skeleton Traps: Set them to ground or air mode depending on the likely attack strategy. They can distract troops and disrupt attacks.
  • Clan Castle Placement: A central Clan Castle is generally recommended, as it forces the attacker to deal with the defending troops early in the attack. However, make sure it’s not too easy to lure.
  • Town Hall Placement: In most War Base designs, the Town Hall is treated as a high-hitpoint building and placed towards the center of the base. It’s not the primary target to protect (preventing the three-star is more important), but it shouldn’t be easily accessible.
  • Anti-Specific Attack Design: While a well rounded base is key, you can slightly tailor your base to defend against popular attack strategies at your Town Hall level.

2.3 Clan Castle Donations

Donating troops to your clanmates’ War Clan Castles is a critical part of Preparation Day. These troops will defend their War Bases during Battle Day.

  • Request Specific Troops: Clan members should request specific troops that complement their War Base design and are effective against common attack strategies.
  • Donate High-Level Troops: Always donate the highest-level troops you have available. Higher-level troops have significantly better stats and can make a huge difference in defense.
  • Common Donation Strategies:
    • Dragons: A versatile option, good against both ground and air.
    • Lava Hounds: Excellent for absorbing damage from Air Defenses.
    • Electro Dragons: High damage output, but can be unpredictable.
    • Witches: Summon Skeletons that can distract and overwhelm attackers.
    • Bowlers: Good against ground attacks, especially when combined with healers.
    • Ice Golems: Tanky troop that freezes defenses upon death.
    • Headhunters: Specifically target enemy heroes.
  • Coordination: Larger clans often have designated donors for specific troop types to ensure efficient and consistent donations.

2.4 Attack Planning and Assignments

  • Discussion: Use clan chat or a third-party communication app (like Discord) to discuss attack strategies and assign targets.
  • Target Selection: Ideally, each clan member should attack a base they are confident they can three-star. However, in practice, this isn’t always possible. A common strategy is to have higher-level players “clean up” lower-level bases after lower-level players have made their attacks.
  • First Attack Strategy: The first attack is often used to scout the base, reveal trap locations, and potentially lure out the Clan Castle troops. It doesn’t always have to be a three-star attempt.
  • Second Attack Strategy: The second attack should be used to go for the three-star, taking advantage of the information gained from the first attack.
  • Reserved Targets: Some clans use a system where members can “reserve” targets to avoid overlapping attacks.

Part 3: Battle Day – Executing Attacks

Battle Day is where all the preparation comes to fruition. Effective attacks require a combination of skill, strategy, and a bit of luck.

3.1 General Attack Principles

  • Understand Your Army Composition: Know the strengths and weaknesses of your chosen army. Are they good against ground or air defenses? Do they have high hitpoints or high damage output?
  • Lure the Clan Castle (Usually): In most cases, you’ll want to lure out the defending Clan Castle troops and eliminate them before deploying your main army. This prevents them from disrupting your attack. Use a small number of troops (like a few Hog Riders or a Giant) to trigger the Clan Castle, then draw the troops to a corner of the map where you can easily kill them with your own troops and spells. Exceptions exist, such as powerful Queen Walks or certain air attacks.
  • Funneling: Funneling is the art of controlling the path of your troops. You want to create a clear path for your main force to enter the base and target the key defenses. Use “trash” buildings (buildings outside the walls) and carefully placed troops to guide your main army.
  • Spell Usage: Spells are crucial for maximizing the effectiveness of your attack.
    • Rage Spells: Increase the attack speed and damage of your troops. Use them when your troops are engaging key defenses.
    • Heal Spells: Heal your troops, especially when they are under heavy fire.
    • Jump Spells: Allow your troops to jump over walls. Use them to create paths to key defenses.
    • Freeze Spells: Freeze enemy defenses, disabling them for a short time. Use them on high-threat defenses like Inferno Towers or Eagle Artillery.
    • Poison Spells: Slow down and damage enemy troops, especially Clan Castle troops.
    • Earthquake Spells: Damage buildings and walls. Four earthquake spells will destroy any level of wall.
    • Haste Spells: Greatly increases troop movement speed. Good for troops like Balloons.
    • Clone Spells: Creates copies of troops. Best used on high-value targets.
    • Invisibility Spells: Makes troops invisible for a short time. Good for sneaking key troops past defenses.
  • Hero Abilities: Use your Hero abilities (Barbarian King’s Iron Fist, Archer Queen’s Royal Cloak, Grand Warden’s Eternal Tome, Royal Champion’s Seeking Shield) strategically to maximize their impact.
  • Time Management: You have three minutes to complete your attack. Don’t rush, but also don’t waste time. Learn to pace your attack effectively.
  • Adapt to the Situation: No attack goes perfectly according to plan. Be prepared to adapt your strategy on the fly based on how the attack is unfolding.

3.2 Common Attack Strategies (by Town Hall Level)

Attack strategies evolve as you progress through Town Hall levels. Here are some common strategies for various Town Hall levels:

  • TH7-TH8:

    • Mass Dragons: A powerful and relatively simple air attack. Use Rage Spells and potentially Lightning Spells to take out Air Defenses.
    • GoWiPe (Golem, Wizard, Pekka): A strong ground attack that can be effective against many bases.
    • Hog Riders: Fast and powerful, but vulnerable to Giant Bombs. Requires careful planning and execution.

  • TH9:

    • LavaLoon (Lava Hound, Balloons): A dominant air attack. Requires precise spell timing and funneling.
    • GoHo (Golem, Hog Riders): A versatile ground attack that combines the tanking ability of Golems with the destructive power of Hog Riders.
    • GoWiWi (Golem, Wizard, Witch): A powerful ground attack that uses Witches to summon Skeletons.
    • Queen Walk: Using the Archer Queen with healers to take out a significant portion of the base before deploying the main army.

  • TH10-TH11:

    • Hybrid (Queen Charge Miners/Hogs): A complex but highly effective attack that combines a Queen Walk with Miners or Hog Riders.
    • Electro Dragon Attacks: Powerful, but can be unpredictable. Requires careful funneling.
    • Bowler Attacks: Effective against ground-based defenses.
    • P.E.K.K.A. BoBat Using a combination of P.E.K.K.As, Bowlers, and Bat Spells

  • TH12-TH16:

    • Queen Charge Lalo: A very advanced and powerful air attack.
    • Hybrid Variations: Continue to be strong.
    • Super Troop Attacks: Utilizing powerful Super Troops (Super Bowlers, Super Dragons, etc.)
    • Blizzard Lalo: Using a Blizzard (Blimp filled with troops) to take out key defenses before deploying the main LavaLoon army.
    • Yeti Smash: Using Yetis, with their tanking ability and spawned Yetimites.
    • Dragon Riders: Powerful air troops that require strategic deployment.

3.3 Analyzing Your Attacks (and Learning from Mistakes)

After each attack, take some time to analyze your performance:

  • Watch the Replay: Identify what went well and what went wrong. Did your troops go where you intended? Did you use your spells effectively? Did you encounter any unexpected traps or Clan Castle troops?
  • Ask for Feedback: Share your replays with your clanmates and ask for constructive criticism. More experienced players can often offer valuable insights.
  • Practice: Practice your attack strategies in multiplayer battles or friendly challenges. The more you practice, the better you’ll become at executing them.
  • Learn from Others: Watch replays of successful attacks by other players, both in your clan and on YouTube or other platforms.

Part 4: Clan War Leagues (CWL)

Clan War Leagues (CWL) is a separate, week-long war event that takes place once a month. It offers a more competitive and structured war experience.

4.1 CWL Basics

  • League System: Clans are placed into leagues based on their performance. The leagues range from Bronze III to Champion I, with higher leagues offering greater rewards.
  • One Attack Per Player: Unlike regular Clan Wars, each player only gets one attack during each war in CWL.
  • Seven Wars in Seven Days: Your clan will face a different opponent each day for seven consecutive days.
  • War Size: CWL wars are typically 15v15 or 30v30, chosen by the clan leader at sign-up.
  • Promotion and Relegation: Clans that perform well in their league will be promoted to a higher league for the next CWL. Clans that perform poorly will be relegated to a lower league.
  • CWL Medals: CWL rewards players with League Medals, which can be used to purchase special items in the League Shop, including Magic Items (Hammers, Books) and exclusive decorations.

4.2 CWL Matchmaking

Unlike regular Clan Wars, CWL matchmaking is primarily based on your clan’s current league. You will be matched with other clans in the same league. There is a small amount of weighting within the league based on strength, but it’s much less significant than in regular wars.

4.3 CWL Strategy

CWL strategy is similar to regular Clan Wars, but with a few key differences:

  • Higher Stakes: With only one attack per player, every attack is crucial. Mistakes are more costly.
  • Consistency is Key: It’s better to consistently get two stars than to gamble on three-star attacks and risk getting zero or one star.
  • Roster Management: Clan leaders need to carefully manage their roster to ensure they have enough active and skilled players for each war.
  • Base Selection: Since you only have one attack, choosing the right base to attack is even more crucial than in normal wars.

Part 5: Advanced Tips and Strategies

5.1 Communication and Coordination

  • Use a Third-Party App: For serious war clans, using a third-party communication app like Discord is highly recommended. Discord allows for better organization, strategy discussion, and attack planning.
  • Call Your Attacks: Have a system for calling targets to avoid overlapping attacks.
  • Share Replays: Encourage clan members to share their attack replays for feedback and analysis.
  • Develop a Clan War Strategy: Establish a clear clan war strategy that outlines expectations for participation, attack planning, and donation requests.

5.2 Base Building

  • Stay Up-to-Date: War base designs are constantly evolving. Keep an eye on popular base designs and adapt your own base accordingly.
  • Test Your Base: Use friendly challenges to test your War Base against different attack strategies.
  • Anti-Meta Bases: Consider designing bases that are specifically designed to counter popular attack strategies at your Town Hall level.

5.3 Attacking

  • Master Multiple Attack Strategies: Don’t rely on just one attack strategy. Be proficient in several different strategies so you can adapt to different base layouts.
  • Learn to Funnel: Funneling is a crucial skill for any successful attacker. Practice funneling techniques in multiplayer battles.
  • Use Your Spells Wisely: Spells are a limited resource. Use them strategically to maximize their impact.
  • Be Patient: Don’t rush your attacks. Take your time to plan your attack and execute it carefully.

5.4 Clan Management

  • Recruit Active Players: A strong war clan needs active and skilled players. Recruit players who are committed to participating in wars and improving their skills.
  • Set Clear Expectations: Establish clear expectations for war participation, donation requests, and attack performance.
  • Provide Feedback: Give constructive feedback to your clanmates to help them improve their attacks.
  • Promote a Positive Clan Environment: A positive and supportive clan environment will encourage participation and teamwork.
