What to know
- The Bell Tolls is a mandatory progression quest tied to Wuling
- You must infuse three separate runes using Xiranite
- A minimum of 800 Xiranite is required to complete the quest
- All runes are located vertically around the bell structure
In Arknights Endfield, mainline progression frequently blends exploration, vertical traversal, and resource investment. The Bell Tolls quest is a perfect example of this design philosophy. While the objective sounds simple on paper—infuse Xiranite into three runes—many players get stuck due to missed platforms, incorrect traversal routes, or underestimating the Xiranite requirement.
This guide breaks down exactly how to infuse all three runes, where to go, and what to prepare in advance. If followed carefully, the quest can be completed smoothly in a single visit without backtracking.
Quest requirements and starting location
Before attempting the quest, preparation is essential. The game does not allow partial completion without resources, and failing mid-way forces unnecessary retracing.
| Requirement | Details |
|---|---|
| Quest name | The Bell Tolls |
| Region | Wuling |
| Specific area | Tianshi Bureau Academy |
| Minimum Xiranite | 1000 units total |
| Traversal tools | Superjump platforms (mandatory) |
You must follow the quest markers to reach the bell structure inside the Tianshi Bureau Academy area. The environment is vertically layered, and the runes are placed at different heights around the bell.
Understanding the rune infusion mechanic
Each rune requires a fixed Xiranite cost, and the infusion is permanent once completed. There is no penalty for infusion order, but pathing efficiency matters because vertical movement options are limited.
| Rune | Xiranite cost |
|---|---|
| First rune | 200 Xiranite |
| Second rune | 500 Xiranite |
| Third rune | 300 Xiranite |
| Total required | 1000 Xiranite |
If you arrive with less than the total requirement, you will be forced to leave the area and return later, which significantly slows progression.
How to Infuse Xiranite into All Three Runes
Step 1: Reach the bell area
Follow the quest marker through Tianshi Bureau Academy until you arrive at the central bell structure. This area serves as the vertical hub for the entire quest. Take a moment to orient yourself, as all rune platforms branch from this location.
Step 2: Use the superjump platform to reach the first rune
Near the bell, you will find a superjump platform positioned to launch you upward. Use it to reach the first elevated platform.
At the top, interact with the rune and infuse it with 200 Xiranite. The animation confirms successful infusion, and the quest tracker will update immediately.
Step 3: Descend and locate the staircase
After infusing the first rune, drop back down carefully. Look around the bell structure to locate a staircase leading to a mid-level walkway. This staircase is easy to miss if you rush.
Take the stairs instead of attempting risky jumps, as falling too far can force a reset to a lower level.
Step 4: Reach the second platform and infuse the rune
At the mid-level, you will see metal railings blocking a direct path. Jump over the rails to access the next platform area.
Once there, interact with the second rune and infuse it with 500 Xiranite. This is the most expensive infusion, and the quest will not proceed without it.
Step 5: Descend again and look for the upper-level access
After completing the second infusion, drop down once more. From here, you need to locate a route leading to the upper level of the structure. This path is less obvious and often causes confusion.
Look for elevated walkways and ramps that spiral or curve upward around the bell’s framework.
Step 6: Reach the superjump platform on the upper level
Once on the upper level, locate another superjump platform. This one launches you toward the highest rune location.
Position yourself carefully before activating it, as missing the landing can force you to repeat the climb.
Step 7: Infuse the third rune and complete the quest
At the top, interact with the final rune and infuse it with 300 Xiranite. After the infusion animation completes, the quest objective updates.
No additional interaction with the bell is required.
Common mistakes that slow down completion
The most frequent issue players encounter is arriving without enough Xiranite, especially after spending resources on upgrades beforehand. Another common mistake is missing the staircase between the first and second runes, leading to unnecessary jumping and falls.
Rushing traversal is also risky. This quest is not timed, and careful movement saves more time than aggressive platforming.
Why to unlock Xiranite before entering Wuling
The Bell Tolls is more than a simple resource sink. It acts as a progression gate, ensuring that players engage with Xiranite production systems before advancing further into Wuling content. Completing it confirms that your infrastructure can support higher-tier crafting and future questlines.
Once finished, you unlock smoother access to upcoming objectives without further interruptions tied to rune mechanics.
The Bell Tolls quest overview
While The Bell Tolls can look intimidating at first due to its vertical design and high Xiranite cost, it is actually very controlled once you understand the layout. With 1000 Xiranite prepared and a clear traversal plan, the quest can be completed in a single uninterrupted run.
Arknights: Endfield has a wide variety of mission types:
- Main Missions: Story-critical quests advancing the plot on Talos-II.
- Side Missions: Optional missions including tasks in regions like Valley IV and other locales.
- Exploration Missions: Scattered across the world for discovery and lore.
“The Bell Tolls” likely falls into the Side/Exploration category, given its exploratory nature and absence from main mission lists.
Take your time, follow the platforms in order, and treat the bell structure as a vertical loop rather than a maze. Done correctly, this quest becomes a satisfying checkpoint rather than a roadblock.
