Wilderness Instance - Whispering Maze

Whispering Maze is a grid-based exploration dungeon that combines the fun of pioneering exploration with randomized challenges. Commanders will lead their squad through layers of fog, searching for rare treasures and pressing onward to the final destination in a cautious adventure. Generous rewards can be obtained after clearing each floor of the maze!

A wide variety of events may be encountered in the maze: treasure chests, battles, hot spring recovery, mysterious altars... And if you discover a Companion, don't hesitate! Fight it and try to capture it!

Whispering Maze is divided into two types, each with a different entrance appearance.

One-Time Mazes: The chests within the maze and the floor-clear rewards can only be claimed once. Their difficulty from low to high is as follows:

  • Shattered Tomb(2 Floors)

  • Bloodmarsh Darkwood (2 Floors)

  • Corrupted Sanctuary (3 Floors)

Repeatable Mazes: Rewards within the maze are randomized, and floor-clear rewards can be obtained repeatedly, as follows:

  • Thousand-Eyed Maze (5 Floors)

Starborne Era Exclusive Treasures

Added treasures exclusive to Stargate Conquest gameplay. These treasures can be collected and cultivated through Stargate-related gameplay to gain stronger stat growth and gameplay benefits.

(Some treasure attributes are not yet fully implemented. Collected treasures will be unlocked in future updates.)

Added New System: Companions

Commanders can collect and cultivate Companions, assign them to their teams to assist in battle, and experience a brand-new system focused on progression and skill combinations.

Companion System Entry: Blackguard System List -> Companion

Companion Acquisition: Obtained from battles in the Starborne Era instance - Whispering Maze

The all-new Companion System is now available. During your adventures, Companions can be obtained through stage drops, packs, and other methods, then brought into battle to fight alongside your team. Each team can deploy up to 1 Companion.

(Currently available in: Starborne Era. More supported modes will be added in future updates~)

This update also introduces the core Companion features, including Training, Leveling, Refining, Fusion, Dismissal, and Skill Book progression. Soulbeast Crystals can be consumed to quickly raise a Companion's level, helping you cultivate higher combat power and better Aptitude.

When captured, Companions will randomly receive one of the following tags: [Wild] [Mutated] [Ordinary].

Wild Companions start with lower initial Aptitude, but can be turned into Ordinary Companions through Refining.

Mutated Companions, on the other hand, possess higher stat growth and special bonuses.

Dismissing Companions will also yield resources such as Soulbeast Crystals, Beast Tears, and Aberrant Beast Tears.

(In future updates, these resources can be exchanged in special shops for Companion growth items such as Skill Books and Refining Potions.)

When fighting in Stargate gameplay, deployed Companions provide substantial bonuses to the entire team, and damage taken by Companions in Stargate battles is additionally reduced by 80%.
