The Secret Source Automaton: Configuration Device is in Toyac Springs, Natlan. From the nearby surface Teleport Waypoint, travel a short distance south to a wooden bridge, find the ravine beneath it, and drop into the underground cavern. Follow the cavern path to reach the boss. The route is a direct exploration trip; the available directions do not identify a quest unlock requirement.
Where is the Secret Source Automaton: Configuration Device?
The boss is located in Toyac Springs in Natlan. Its entrance is not presented as a marked surface arena. Instead, the practical route described by location guides starts at the surface Teleport Waypoint near the boss, then uses a wooden bridge and the ravine underneath it as visual landmarks.
Look for the opening below the bridge rather than searching for a large arena structure above ground. The boss chamber is underground, so reaching the correct region is only the first part of the trip.
How do I reach the boss step by step?
Use this route from the surface waypoint:
- Teleport to the nearby surface Waypoint in Toyac Springs. Start from the waypoint in the open area rather than trying to navigate to an underground marker.
- Head a short distance south. You are looking for a wooden bridge. The bridge is the most useful surface landmark in the route directions.
- Check below the bridge for the ravine. The entrance is in the cut in the ground beneath the bridge, not at either end of the bridge.
- Drop down into the cavern. Descend through the ravine opening to enter the underground area. The fall is the intended transition into the boss route.
- Follow the cavern path. Continue through the underground passage until it leads to the Configuration Device’s arena.
- Begin the encounter once you reach the arena. No separate surface door, puzzle, or quest step is identified in the route directions.
If you are still above ground after reaching the bridge, you have not yet found the entrance. If you have dropped into a cavity but cannot see the arena, stay underground and continue along the passage instead of climbing back to the waypoint.
Do I need to complete a quest before entering?
No quest prerequisite is identified in the available location directions. The route guides describe reaching the cavern directly from the surface, while HoYoverse’s Version 5.1 update details place the boss in Toyac Springs without listing an unlock mission for the encounter.
That qualification matters because the official update confirms the regional location but does not document every step of the physical entrance. If the entrance is not immediately obvious, treat the problem as navigation first: return to the surface waypoint, move south, and recheck the ravine below the bridge.
What happens when the fight starts?
The Configuration Device has a mechanic tied to Nightsoul’s Blessing. HoYoverse describes the process in the Version 5.1 update details:
“When characters enter and maintain the Nightsoul’s Blessing state, the Secret Source Automaton: Configuration Device will start progressing through its Adaptive Countermeasures.”
In practical terms, maintaining a character in Nightsoul’s Blessing advances the boss’s Adaptive Countermeasures. This is a combat-system interaction, not a condition for opening the cavern; you can reach the arena through the route above without treating Nightsoul’s Blessing as an access key.
How do I interrupt the Boltsphere Cannon sequence?
After the Adaptive Countermeasures progression, the boss prepares the Boltsphere Cannon and activates Accretion Mechanisms. The way to stop the charge is to use the temporary terrain and energy field created during this sequence.
- Watch for the Accretion Mechanisms to activate. Their appearance signals that the cannon sequence is in progress.
- Climb the Solid Phlogiston. HoYoverse specifically directs players to use this solidified Phlogiston as the route upward.
- Enter the energy field. Move into the field associated with the mechanism rather than waiting on the ground.
- Attack an Accretion Mechanism. Damaging the mechanism in the energy field lets you destroy it and interrupt the cannon’s charge.
The important distinction is that the cannon is not stopped simply by attacking the boss from the floor. During this sequence, the mechanism and the elevated Solid Phlogiston route are the intended objectives.
What should I do if I cannot find the entrance?
| What you see | What it usually means on this route | Next action |
|---|---|---|
| You are at the waypoint but see no boss arena | The arena is underground rather than beside the waypoint. | Move south and search for the bridge. |
| You found the bridge but no doorway | The entrance is below the bridge in the ravine. | Look beneath the bridge and descend through the opening. |
| You dropped into a cavern and reached a dead-looking space | You may be in the entrance cavity rather than at the arena. | Continue along the underground path before returning to the surface. |
| The Boltsphere Cannon is charging | An Accretion Mechanism is active. | Climb the Solid Phlogiston, enter the energy field, and attack the mechanism. |
These landmarks are practical navigation directions, not official coordinate labels. HoYoverse names Toyac Springs as the location and explains the combat mechanic, while the bridge-and-ravine description comes from route guides.
Which parts of the route are officially confirmed?
There are two levels of information behind the directions:
- Official location and mechanics: HoYoverse’s Version 5.1 update details identify Toyac Springs and explain Nightsoul’s Blessing, Adaptive Countermeasures, the Boltsphere Cannon, Solid Phlogiston, and Accretion Mechanisms.
- Practical entrance landmarks: Game8 and Beebom describe the nearby surface waypoint, the short southward walk, the wooden bridge, and the ravine beneath it. Game8’s route page is reported as updated March 7, 2026; the exact publication date of the corroborating Beebom guide is not established here.
Because the official update does not provide a coordinate or name the bridge as an official landmark, use the bridge and ravine as visual directions for finding the cavern rather than expecting those words to appear as map labels.
What is the shortest reliable checklist?
- Start at the surface Teleport Waypoint in Toyac Springs.
- Travel south until you reach the wooden bridge.
- Descend into the ravine directly beneath it.
- Follow the underground passage to the arena.
- During the cannon sequence, use Solid Phlogiston to reach the energy field and destroy an Accretion Mechanism.
Once you know that the encounter is below the bridge rather than on the surface, the route is straightforward. The only special combat instruction supplied for the encounter is the mechanism interruption during the Boltsphere Cannon charge.
Frequently Asked Questions
Is the wooden bridge an official map landmark?
Not in the official location description. HoYoverse identifies Toyac Springs, while the bridge and ravine are visual landmarks supplied by route guides to make the underground entrance easier to recognize.
Does Nightsoul’s Blessing unlock the cavern?
No. It affects the Configuration Device after the encounter begins by advancing Adaptive Countermeasures; the available directions describe access as a surface-to-cavern route rather than a Nightsoul-gated entrance.
Why are there no exact coordinates for this boss?
The official Version 5.1 update names the region but does not publish a coordinate or a detailed entrance diagram. The practical directions therefore rely on the waypoint, bridge, and ravine instead of a numerical location.
Which game update introduced the boss information?
The relevant HoYoverse information appears in the Version 5.1 update details from 2024. A later Game8 route page, reported as updated March 7, 2026, provides the more specific entrance landmarks.
