Alliance Treasure Hunt (ATH) is a weekly event that gives players the opportunity to earn special rewards.
Your heroes embark on an adventure to a tropical island to battle against pirates. Each battle requires compasses, which are gained every 90 minutes.
Rewards include premium items such as Fountain of Youth tokens, Mastery Points, Folios of Enlightenment and a truckload of customizations for your city buildings.
Treasure Hunt
The Alliance Treasure Hunt (ATH) is a weekly event that begins on Friday at 2 PM (CET) and ends the following Thursday at 2 PM (CET). During this time, alliance members embark on an adventure on a tropical island, where they battle pirates and earn a wealth of rewards, including Folios of Enlightenment

, special building customizations, Mastery Points and Tokens for the Fountain of Youth evolving building. Each completed encounter contributes to the alliance's overall progress. Alliances compete in rankings, which are adjusted weekly to ensure that only comparable alliances face off against each other.
How to participate
To participate in the ATH, you must have researched the Alliances technology, which becomes available at the beginning of the Bronze Age. If you change your alliance during an ATH round, you can continue playing ATH in your new alliance; however, your score will not contribute to their milestones, nor will you be able to collect rewards from them. You can play ATH even without being in an alliance, but you will not receive any milestone rewards.
Difficulties
ATH features 9 difficulty levels, ensuring that you always face opponents of comparable strength and receive rewards relevant to your current in-game progress. Higher difficulties unlock as you advance through the ages or complete the previous ones and generally offer more valuable prizes, including more powerful completion rewards for finishing the first three stages. The fourth stage is a bonus stage that allows you to earn additional rewards and ranking points for your alliance. The higher difficulties also grant more ranking points for your alliance with each completed encounter. Once you select a difficulty for the week, it cannot be changed, but you can choose a different one when the next ATH begins.
Compasses
Unlike in the Campaign, where Stamina

is used, in ATH you need Compasses to initiate battles. Each encounter costs 1 Compass to start. The ATH week begins with 5 Compasses, which regenerate every 1.5 hours. There is a cap of 15 Compasses at a time, so it's important to play regularly to be able to complete the ATH. Additional Compasses can be purchased with Coins

or Gems

, but they are quite expensive. When playing actively and not losing too many battles, however, the free Compasses you generate should be sufficient to complete the event.
Healing Shrines
The most significant difference between the Campaign and ATH is that in ATH, your heroes retain their health status from one encounter to the next. As you progress, you'll notice your heroes growing weaker, often requiring you to use heroes you don’t typically rely on. Fortunately, there's a solution: after each boss battle (every fifth encounter), you'll encounter a Healing Shrine. Here, a group of pirates will demand resources in exchange for healing your heroes by 50%. To negotiate with them, you'll need to complete a minigame. Once your heroes are healed, you can continue using them in ATH battles. Keep in mind that healers are especially valuable in ATH, as they play a crucial role in keeping your heroes alive.
