Clan Siege is a recurring Clan Event that was introduced in Update 3.0. Clans must have a fully hatched Clan Dragon to qualify for participation. During the event, Clan members must complete various tasks to earn the Spellbooks needed to summon Clan Siege Sprites . The sprites are then used by the Clan Dragon to attack the opposing Clan's base. The event runs for 4 days and all qualified Clans are split into groups of two, in accordance to the league they are currently in. For the entire duration of the event, the Clan Dragon of the concurrent Clan will be strolling near each individual Clan member's Clan Fortress, occasionally hurling sprites at the player's Fortress or Clan Dragon.
For the duration of this event, Clan Quests, in addition to their regular rewards, will also award Spellbooks. The number of Spellbooks given by a quest is randomly-generated by the game, thus no particular amount is bound to a particular type of quest. 3 or 5 Spellbooks can be earned per quest.
Each Clan Siege Sprite takes 3 hours to be summoned in exchange for 2 Spellbooks. The waiting time can be skipped in exchange for Gems. Each Clan member can have a maximum of 5 sprites at any given time. The amount can be increased to 6 if the player has an active VIP membership. The Spellbooks and sprites the player currently has can be seen by accessing the event screen. From here, players can request a Spellbook donation once every 3 hours by pressing the button next to the total amount of Spellbooks, and then pressing the button. Whenever any member makes a request for Spellbooks, a notification will be shown at the bottom-right corner of the tab. The request will automatically be for 5 Spellbooks and will be shown in the Clan chat. Each Clan member can donate 1 to 5 Spellbooks per request, with the maximum limit being set at 5. However, multiple members can donate. Donating is done by pressing the button to the right of the Spellbook. Each Clan member can donate up to a total of 40 Spellbooks per day on various requests. Pressing the button right next to the Spellbook will show the player how many times they donated for that day and how much time is left until the limit for donations resets.
Once the player has enough Spellbooks to summon a Sprite, they can press the button under any of the unsummoned sprites. All the sprites can be summoned at the same time, provided the player has enough Spellbooks to do so. The button will be shown under the slot for the last Sprite if the player's VIP membership is inactive.
Once a Sprite is summoned, it can be used by the Clan Dragon to attack the opposing Clan's base. Accessing the Clan battle screen is done through the button which is found under the Clan Siege Sprites. Each Clan base is defended by five towers and the Clan Dragon itself.
Once a tower is engaged in battle, the Clan Dragon will be given three different spots at which it will be able to hurl a Sprite. Each spot has a particular chance of being hit. The higher the chance to hit the spot, the lower the damage caused by the Clan Dragon will be. Conversely, the lower the chance to hit the spot, the higher the damage will be. Pressing the button under any of the spots will use up one of the available sprites. If there are no sprites available, a window will appear, giving the player the option to summon sprites through the button. The towers can be attacked in any order, but it is mandatory that all towers be destroyed before proceeding to engage the opposing Clan Dragon.
Once all the five towers are defeated, the Clan can proceed to attack the enemy Clan Dragon itself. The same mechanics apply to attacking Clan Dragons as it does to the towers. However, once the opposing Clan Dragon's hit points are drained completely, its hit points will be fully restored, allowing the Clan to attack it again, in order to earn a higher score multiplier. Each time its hit points are restored, the amount also increases. At the end of the event, the Clan with the highest amount of damage dealt will emerge victorious.
The hit points of the towers and the Clan Dragon are all different among each other and those for the towers depend on the league the clashing Clans are currently in while those of the Clan Dragon are the same across all leagues.

There are three types of damage that can be inflicted, namely low, medium and high. Each sprite hurled at the opposition is a guaranteed hit while there is a particular percentage of success for a critical hit to be inflicted. The chance of landing a critical hit is different for each tower and the Clan Dragon. However, the spots, types of damage and critical hit percentages are not affected by the league and are the same in all of the leagues.

See Limited Collections for details about the rewarded Dragons
There are three different sources that reward participating players with prizes, namely progress or milestone rewards, the MVP reward, and the victor reward. The MVP reward is fixed while the other two depend on the league the participating Clans are in. Clans in higher leagues will receive better rewards, but the requirements will also be higher.
There are ten milestone rewards for the Clan to reach collectively and they are affected by the Clan league. Five milestones are tied to the towers and defeating a tower rewards one of Gold, Gems or card packs that give Dragon Pieces only for Blazebird Dragon, Cinder Dragon, Hazmat Dragon, Knight Dragon, Noble Dragon, Orc Dragon, Quake Dragon, Shuriken Dragon, Skater Dragon and/or Treasure Dragon. The other five milestones are tied to the Clan Dragon.
|Top Left||Bottom Left||Middle||Bottom Right||Top Right|
|1||1 (1 Dragon Piece)||(1,500*Level Modifier) Gold||1 (1 Dragon Piece)|
|2||1 (2 Dragon Pieces)||3 Gems||1 (2 Dragon Pieces)|
|3||1 (3 Dragon Pieces)||5 Gems||1 (3 Dragon Pieces)|
|4||1 (4 Dragon Pieces)||7 Gems||1 (4 Dragon Pieces)|
Each time the hit points of the opposing Clan Dragon are completely drained, each member of the Clan is awarded a certain amount of Gems. The amount depends on the league the attacking Clan is in. Once the sixth reward is obtained, the same amount of Gems that was given for this reward will also be given each time the attacking Clan defeats the opposing Clan Dragon.
MVP Bonus Reward
The most active member of the week will be awarded status and a certain amount of Clan Coins, depending on the league their Clan is in. Members can see the current MVP rankings by going to the menu where sprites can be summoned and pressing the button. The rankings can also be accessed by opening the Clan interface, selecting the option, then pressing the tab. The latter option can also be used when there is no ongoing Clan Event, while the former can only be used during an ongoing event.
The victor reward is given to the Clan that emerged victorious out of the two, but it is only awarded if the Clan managed to achieve a score equal to the tower with the highest health points. Otherwise, no reward is given to either side. The prize consists of a card pack containing 3 Dragon Pieces for Clan Dragons. The Dragon Pieces that are found in this card pack depend on the league of the winning Clan.
As only one of each Dragon can be owned, the applicable card will automatically be compensated for by being replaced with a certain amount of Clan Coins in the event that this occurs. Thus, 50 are given for Ruptia, 125 for Striker, 200 for Gravelis, 350 for Amoura, and 500 for Brimstone, Kutter and Boone.
