The Chamber of Elements is a major part of the custom progression system in Chronicles of Arcadia, continuing the journey that begins in the Secret Temple of Tikal. Hidden within the Port of Thousand Heavens in the Lost Island of Atlantis, this chamber serves as a gateway to three elemental instances, each housing a powerful core required for crafting and upgrading high-tier gear.
Inside the chamber, players can unlock and progress through the elemental paths in the fixed order:
Through these instances, players gather materials needed to advance their equipment toward gold quality.

The Chamber of Elements itself has no entry requirements. However, the three instances inside the chamber do have requirements.
To access any of the elemental instances, players must first complete:
| Level | Quest Name | Quest ID | NPC Name |
|---|---|---|---|
| 104 | Proof of Power | 427920 | Taurelias Maeva |
| 104 | Understand the Happenings | 427921 | Mercia Thannis |
The Chamber of Elements is accessed via a portal in the Port of Thousand Heavens, located in the Lost Island of Atlantis. It acts as a central hub that connects directly to all three elemental realms.

The first elemental path is located on the right side of the chamber. After completing the introductory steps inside the chamber, players receive a mission to defeat all bosses within the Inferno of Divinity. Clearing the final boss rewards the Fire Core, which is used alongside the Temple Core and Weak Core to create your first gold equipment.
| Level | Quest Name | Quest ID | NPC Name |
|---|---|---|---|
| 104 | Explore the Inferno | 427922 | Mercia Thannis |

Once the Fire instance is completed, the Ice path unlocks. Players then receive a quest that sends them to the Gorge of the Ice Giants, a frozen region filled with ancient Ice Giants and powerful guardians. Defeating the last boss grants the Ice Core, another essential upgrade material.
| Level | Quest Name | Quest ID | NPC Name |
|---|---|---|---|
| 104 | Explore the Gorge | 427930 | Mercia Thannis |

The final elemental route leads to the Realm of Forgotten Legends. After finishing the Ice quests, players gain access to this instance, where clearing all bosses and completing the dungeon quest rewards the Earth Core, the final core needed for gear upgrades.
| Level | Quest Name | Quest ID | NPC Name |
|---|---|---|---|
| 104 | Explore the Realm | 427932 | Mercia Thannis |
This instance includes three difficulty modes:
The most common and recommended mode for progression is Hard.

After completing all Chamber of Elements content, players gain access to a special task involving Hekhig, an ancient Dwarven Chief Engineer. He is responsible for upgrading red Realm of Forgotten Legends gear into Final Form (Gold).
To unlock him, players must discover multiple hidden secrets scattered within the Realm of Forgotten Legends. After all secrets are found, Hekhig appears near the Chamber entrance, ready to assist with high-tier upgrades.
