Helliquary

"Muster your courage and rally your friends. More mayhem is coming to the Helliquary. Helliquary bosses are now designed for raids of eight players. This is one of many changes we’re making to PvE, to make it more challenging and rewarding to players who complete these objectives as they cycle weekly."

- Mode description

Helliquary is a gameplay system of Diablo Immortal. It is intended for endgame play.

Lore
Built by Rayek, the Helliquary was built to locate particularly destructive demons and trap their essence when they're slain. Rayek hoped to use his creation to stop demonic incursions before they happened, and prevent the doom that came to his homeland from ruining other lands.

Once the demon is defeated, the Helliquary can turn their remains into power an adventurer can take advantage of. Though unstable, the Helliquary is capable of funneling the power of defeated demons to a sufficiently daring subject. The risks of such a process remain unknown.

Gameplay
The Helliquary becomes available once two conditions have been met&mdash;the player's character is at level 41, and the Bilefen main questline has been completed. After this, players will reunite with Deckard Cain in his workshop. Cain introduces the player to Rayek, who's developed the Helliquary.

The Helliquary allows up to 8 players at a time (this can be in a warband) to locate and defeat bosses in order to not only power up their characters, but also to benchmark their power. One boss will be added to the Helliquary each month upon the game's launch. If a player's character defeats a boss, they receive a power boost. Multiple difficulty levels are available for each boss.

The Helliquary needs to level up to handle additional demonic remains as the player progresses. To level-up the Helliquary, heroes need to earn Scoria, a special material that can only be refined by Charsi. Charsi will refine Scoria into Hellfire Scoria, the material used to ascend this device. As the Helliquary ranks up, the player becomes imbued with more power. At specific intervals in the Helliquary’s progression, opportunities to confront powerful demons will arise.

Each player has one revive in the Helliquary. Otherwise, they need to rely on other players to revive them.

The Helliquary has a leaderboard system, where warbands compete for the best positions. The top leaderboard team gains extra Scoria.

Objectives are cycled weekly.

List of Bosses

Development
The Helliquary originally unlocked between levels 41–45. Originally, the Helliquary was said to have been developed by Charsi, while in the final version, its creation can better be attributed to Rayek.
