⚔️ Clan War — The Ultimate Clan Competition
Clan War is a competitive event where five clans face off in a battle of strategy, coordination, and smart deck building.
Victory isn’t just about power — it’s about planning, teamwork, and choosing the right matchups.
Below is a clear breakdown of how Clan War works.
🏗️ Event Structure: Two Phases
Clan War is divided into two phases:
- Preparation Phase — 3 days
- Attack Phase — 6 days
Each phase plays a critical role in determining the final outcome.
🛡️ Preparation Phase (3 Days)
This phase is all about setting up your clan for battle.
Deck Registration Rules
- Each player can register up to 4 decks
- Every deck must include:
- Cards can only be used once across all decks
- No duplicate Heroes, Towers, or Skills
- Core Parts attached to cards are included and affect deck power
Participation Requirement
- To participate in Clan War, at least 10 clan members must create and lock their decks during the Preparation Phase
- If this requirement is not met, the clan cannot join Clan War
Important Notes
- Decks can be edited freely during the Preparation Phase
- All decks must be manually locked to participate
- If fewer than 10 players lock their decks, the clan cannot join the event
- Players may switch clans during the Preparation Phase
- Once the Attack Phase begins, you cannot join the event until the next one
⚔️ Attack Phase (6 Days)
Once the war begins, it’s time to fight.
Daily Attack Rules
- You can create up to 4 decks, and each of your decks can attack once per day.
- For each attack, you’ll see one available deck from each of the other 4 clans.
- You may choose any matchup.
- Once you attack an opponent's deck with one of your decks, that matchup becomes unavailable for you until the next daily reset. • Your same deck can be attacked by multiple players from all clans.
- However, you cannot attack or be attacked by the same opponent deck more than once per day.
- After you use one of your decks, it cannot be used again until the daily reset.
Damage Rules
- Success deals damage equal to the opponent’s deck power
- Fail still deals damage, but a Lose Penalty is applied
- Your own Clan Castle is never affected by your attacks
Daily reset occurs at 00:00 UTC, refreshing all decks for the next day
🔍 Search & Matchups
- Use the Search screen to find available decks from rival clans.
- Your own clan’s decks will never appear here.
- Each day, you’ll see one available deck from each opposing clan.
- Not satisfied with the current options? Use Refresh to generate new matchups.
- Remember: each of your decks can attack once per day, and you cannot attack the same opponent deck twice in the same day.
Clan War isn’t just about attacking — defense matters
- Daily Repair Missions are available during the event
- Completing missions contributes to your clan’s Repair Progress
- Repair milestones unlock bonuses for the clan
- Each player can contribute once per milestone
- Repair progress does not reset during the event
Stay active to help keep your Clan Castle standing
