War Shield


  • In Clan Wars, Clans compete against other Clans for rewards and Clan Trophies.
  • Clan Wars are found under the Clan tab.
  • Clan Wars are always ongoing; they do not need to be started by a Leader or Co-Leader. Each War will last for 4-5 weeks, with 1 “River Race” each week.
  • All Clan members who are at least King Level 6 and have attacks left are able to participate. However, the Clan must have at least 10 eligible participants to start a War. Dropping below the eligible threshold will not remove a Clan mid-War. Additionally, only up to 50 unique participants can play in each day's Clan War.
  • A Clan War is fought between 5 Clans. However, all battles are matched against random opponents. The goal of the war is to reach the River Race's finish line before the other Clans by engaging in battle. Participating in battles at all rewards "Medals", which help the Clan progress towards the Finish Line, as well as Gold.
  • The first 3 days of a Clan War are Training Days, where Clan Boats cannot progress on the river or be attacked (battles only reward Gold), while the last 4 days are Battle Days which do allow Clan Boats to progress to the Finish Line (battles reward Medals and Gold).
  • Once a Clan reaches the Finish Line, they receive a special Chest containing different rewards based on their placement.
  • If a Clan does not reach the Finish Line before the Clan War ends, they will receive a Chest as long as they have played enough battles to be considered participating. If a Clan fails to play enough battles before the end of the war, participants will still receive a small amount of rewards in the form of a boot.

River Race[]

  • Players will create 4 different War Decks using their own Card collection and Levels. Cards cannot be repeatedly used across decks; all 4 decks must be comprised of 32 unique cards. Once a War Deck is used, it cannot be used again until the following day.
    • Next to the "Average Elixir cost" metric in the deck builder, there is a "Magic" wand button that can randomly create a deck out of unused cards.
    • Tapping on unfilled card slots will make a prompt pop up with 3 cards and a role that they can fill, giving the player the option to add 1 of the 3 or reroll the choices available to them. The categories are as follows:
  • On the River are various River Tasks that participants can attempt. They will reward Gold (on Training Days) or Medals and Gold (on Battle Days) with more being rewarded upon a victory. These tasks include:
    • 1v1 Battle - functionally identical to those on Trophy Road matches.
    • Duels - a best of 3 set of 1v1 Battles. 3 War Decks must be available for use to play this mode. Duels reward more Gold than 3 separate 1v1 Battles would.
      • If a Duel is completed with only 2 War Decks, the 3rd War Deck will stay available for use in other modes.
      • If a Duel ends in a stalemate (both players have the same amount of Tower hitpoints after a tiebreaker), a coin flip will then decide the winner.
    • Colosseum - a special Duel mode only available in the final week's River Race for clans that finished the half-length River Race. It awards more Victory Gold than the regular Duel (matchmaking uses the same player pool).
    • Rotating Game Mode - each week, a different Special Event game mode is available, similar to how the Party button functions. The current game modes available are Double Elixir, Triple Elixir, Infinite Elixir, Sudden Death, and Rage Battles.
    • Boat Battles - players can attack the defenses that other Clans have set up on their Clan Boat in an attempt to slow their progress in the River Race.
  • The amount of Medals gained from River Tasks is dependent on which mode they played, and the result of the battle (see table below).
  • At the end of each Battle Day, Clans will move forward a certain amount on the river dependent on their total Medals gained for the day relative to the other clans. A Clan will finish the race when they have accumulated 10,000 movement points (5,000 in the final week). If a clan has not finished the race by the end of the week, they can still be eligible for participation rewards.
  • After reaching the Finish Line, players can still play Duels (or Colosseum Duels in the final week), Rotating Game Modes, and 1v1 Battles for victory Gold and Crowns (counting towards Pass Royale and Bonus Bank).

Clan Boat[]

  • Each Clan has a Clan Boat to move down the River. On Battle Days, Clans can attack other boats in Boat Battles, where players will use a War deck to try and take down Defense Towers of an opposing clan in a PvE battle.
  • Each Clan Boat has up to 15 Boat Defenses (amount depending on Clan War League level), each one equipped with 3 Defense Towers. Each player in control of a Boat Defense can set up each Defense Tower with 4 Cards from their own collection and Levels. These cards can overlap with the cards in their War decks. The same "Magic" wand button that appears when building War Decks can be tapped to randomly create a deck for a Defense Tower.
    • Defense Towers can attack both ground and air transport units, but cannot deploy any cards until they have been damaged.
    • From the start of the Boat Battle, the attacker will generate Elixir slightly faster than normal, at 1.5x times Elixir.
    • Upon the destruction of any Defense Tower, all attacking troops will be eliminated (death spawn still survives) and the attacker will restore all Elixir, gain 2.7 times Elixir generate rate and the battle timer is set to 60 seconds.
    • Even if a Boat Attack is unsuccessful, damage persists between attacks, meaning a weakened Defense Tower will stay weakened for other Clan members.
    • If at least 1 Defense Tower is destroyed, the attack will be considered a victory. Defeating all 3 Defense Towers will take down the Boat Defense.
    • Boat Defenses which remain intact at the end of each day will award bonus movement points. Boat Defenses constructed sooner award more movement points than Boat Defenses constructed later.
    • Destroyed Boat Defenses stay destroyed until the end of that week's Race, and will not award movement points while they are destroyed.
    • Currently, the Elixir Collector, Mirror, and Clone cannot be set on Defense Towers.


  • An NPC is available on the River for players to trade with, as opposed to needing to coordinate with other Clan members. Like regular trades, the player will need the respective token in order to complete the trade. Doing trades will not reward any Medals or Gold, however.
  • Players will choose 1 of 3 pre-selected cards to give to the Trader. The player will also choose from 1 of 3 pre-selected cards to receive from him. The rarity of the trade is also randomly set, with Epic cards always appearing every Sunday, and trades between two different rarities are not possible.
  • Players can reroll the possible list of cards they can give to the Trader or receive from the Trader for 10 Gems.
  • The Trader's deal will reset every day at midnight of the player's local time zone.


  • Finishing the River Race sooner than other Clans will grant greater rewards.
    • All Clans who are considered to have participated in the Clan War will receive a River Chest. Higher placements increase the cards and Gold awarded; finishing 1st in any League will guarantee a Legendary card inside the River Chest, with subsequent placements reducing the likelihood of a Legendary card to drop.
    • Clan Trophies are earned by the Clans who placed 1st and 2nd in the River Race. Clan Trophies indicate the Clan's success in Clan Wars. At higher leagues, placing 3rd or below will cause the Clan to lose Trophies. Gaining more Clan Trophies will allow the Clan to advance in Clan Leagues and earn better base rewards from the River Chest at the end of each River Race.
  • In the final week, the River Chests are determined by the order of finishing the half-length River Race, but Clan Trophies (gained and lost being five times those of the regular River Race) are determined by the total Medals gained in the week instead.
  • Clans which reach the end of the River Race on the same day will tie and receive the same placement and rewards.
  • Only players who participated in the River Race can claim the River Chest. Players who participated, but are not present in the Clan at the race's conclusion cannot claim the River Chest.
  • If a Clan does not play a certain amount of battles in the Clan War before its end, they will receive a reward boot rather than a Chest.



  • Clan Wars were added on the game on 25/4/2018, in the Clan Wars Update. On the same day, a maintenance break, fixed an issue that caused non-Draft Collection Day game modes to be played with tournament Levels instead of the player's own card Levels.
