Elemental Cradle

Elemental Cradle becomes available at team level 35. It is located in Celestial City.

You will find Castle Ruins, Merchant, Altar of the Elements, and Titan Artifacts here. 

In Castle Ruins, you fight a mighty opponent, Hydra.  

Hydra has five levels:

• Common Hydra,
• Elder Hydra,
• Ancient Hydra,
• Dreadful Hydra,
• Legendary Hydra.

To attack a higher-level Hydra, you must defeat the Hydra of the previous level. If you beat a Hydra of a certain level, this level stays permanently unlocked.

In addition, Hydra has six heads: Darkness, Water, Earth, Fire, Wind, and Light. Each head is unique and requires a specific strategy to win. To learn more about each head, click the Info icon in the upper-left corner after selecting Hydra level in Castle Ruins. 

You can fight Hydra together with your guildmates. However, if a Guild member is fighting a Hydra head, others cannot attack it.

Note
Hydra is immune to crowd control. It cannot be stunned, knocked up, or charmed. It has magical and physical protection and does not have energy.

To attack Hydra, you need Horns of Summoning. Each Horn of Summoning grants one attack attempt. Every day at 02:00 UTC, the number of Horns of Summoning resets to three. Horns do not stack. If you have not used a Horn, you will not get an additional one with the daily reset.

Moreover, there are Golden Horns of Summoning. Each Golden Horn grants one attempt to attack Hydra even if you have spent all regular Horns. Golden Horns of Summoning can stack and do not expire. You do not lose them if you quit your Guild.

You can get a Golden Horn of Summoning from a Golden Horn Box or buy it in Titan Soul Shop for 15,000 Titan Potions. Note that you can open Golden Horn Box only if you are a member of a Guild. 

Depending on Hydra's level and the number of heads defeated, each Guild member receives a letter to the in-game mail with a reward. The reward always grants Fairy Dust used to level up titan artifacts and might contain Elemental Spheres used to obtain artifact fragments in the Altar of the Elements. You can preview all possible rewards by tapping the three stripes button in the Hydra selection menu.

In Altar of the Elements, you can open Elemental Spheres to get various recourses. Titan artifact fragments are the primary reward. You may also get other valuable resources: Fairy Dust, Hydra Coins, and the grand prize, Golden Horn Box.

You can spend Hydra Coins from Altar of the Elements in Hydra Shop. It becomes available at level 35. There are two ways to open the shop.

You can open it on the Elemental Cradle screen:

1. Tap Guild.
2. Press the Elemental Cradle button.
3. Tap Merchant.

Or you can go to the main game screen and press Merchant:

In Hydra Shop, you can purchase Yasmine and Morrigan Soul Stones, Elemental Spheres, chests with hero artifact resources, Artifact Coins, Sparks of Power, Chaos Cores, and gold. Items in the shop do not change. 

The goods reappear every 24 hours at 9 PM your local time. Also, you can refresh the Shop using emeralds.

You can also get Hydra Coins by exchanging extra titan artifact fragments in your Inventory.

Exchange rate: 1 fragment = 2 Hydra Coins.

In Titan Artifacts, you can awaken powerful titan artifacts. There are three types of artifacts:

• Artifact Weapon,
• Artifact Crown,
• Artifact Seal.

Artifact Weapon is unique for every titan. You cannot use fragments of a specific titan's Artifact Weapon to upgrade another titan's Artifact Weapon.

When a titan's first skill triggers, their Artifact Weapon grants the whole team bonus characteristics listed in the Weapon's description. This bonus is not permanent and lasts only for nine seconds.

Artifact Crown depends on a titan's element: earth titans get Earth Crown, while water and fire titans get Water Crown and Fire Crown. Light titans get the Crown of Light, and dark titans — the Crown of Darkness.

Artifact Crown passively adds two bonus characteristics to a titan: extra damage and defense against titans of a specific element. The element is selected according to this cycle:

• water titans get extra damage and defense against fire titans;
• fire titans get extra damage and defense against earth titans;
• earth titans get extra attack and defense against Water titans.

Light and dark Crowns give extra attack and defense against fire, water, and earth titans.

The Artifact Crown bonus works both in attack and defense.

Artifact Seals passively increase titans' physical attack and health. Titans get Artifact Seal based on their role:

Artifact Seal	Titans	Appearance
Balance Seal	Hyperion, Avalon, Mairi, Ignis
Defense Seal	Eden, Angus, Sigurd, Moloch
Attack Seal	Araji, Nova, Vulcan, Sylva, Keros, Amon

To increase titan artifact star rank, you need the following number of fragments:

Stars	Fragments required
1st star	15
2nd stars	300
3rd stars	900
4th stars	1,500
5th stars	4,500
6th stars	15,000

You can also increase the titan artifact level. There are two ways to do that:

• using Fairy Dust and gold;
• using emeralds. 

Whenever you upgrade a titan artifact, you gain Sparks of Power that you can spend to upgrade your heroes.
