Burdenbeasts are one of the more practical overworld targets in Arknights Endfield. If you are working to optimize your Eco-Plots or to rush Crafting Manual milestones, you will need a steady supply of Burdo-Muck. This guide walks you through where to find Burdenbeasts, how to efficiently farm them, and how to turn their drops into Fertilizer.

Location of Burdenbeasts in Arknights Endfield
Burdenbeasts primarily roam the wetlands and transitional terrain zones of Jingyu Valley, especially around Wuling City and its surrounding outskirts. Based on current exploration markers and regional layouts, you will consistently encounter them in several key sub-regions.
Sky King Flats and surrounding marshlands
The Sky King Flats area is one of the most reliable early farming routes. You can patrol the perimeter paths and nearby shallow wetlands for repeat spawns. The relatively open terrain makes combat quick and efficient, especially if you are running AoE-focused units.

Outskirt Barrens and Suzhou Marsh corridor
Moving south and southeast from Wuling City toward Outskirt Barrens and Suzhou Marsh increases spawn density.

These zones mix shallow water terrain with open land, making them natural habitats for Burdenbeasts. If you are planning a circular farming route, start at Outskirt Barrens and loop through Suzhou Marsh for optimal uptime.

Field Logistics Depot Courtyard outskirts
On the eastern side of the region, around Tianshi Pillar Array and near Tianjing Courtyard, you can find additional Burdenbeasts scattered along the outer edges. These are slightly more spaced out but useful if you are already completing exploration or clearing other mobs in the area.

If you want maximum efficiency, rotate between Sky King Flats, Outskirt Barrens, and Suzhou Marsh in a continuous loop while fast-traveling back to reset enemy groups.
How to farm Burdo-Muck efficiently
Fast travel to a waypoint near Sky King Flats or Outskirt Barrens to begin your farming loop close to high-density spawn zones.

Collect Burdo-Muck drops immediately after petting to avoid missing materials during extended farming sessions.

If you maintain a clean rotation, you can gather enough Burdo-Muck for multiple Fertilizer crafts in a short session.
How to unlock the Fertilizer recipe from Pu Yuan
- Before crafting Fertilizer, you must purchase the recipe.
- Travel to Wuling City in Jingyu Valley.
- Locate Pu Yuan near the city entrance. He operates as a merchant offering select crafting recipes.
- Purchase the Fertilizer recipe from his inventory.
- Once acquired, the recipe becomes available at your crafting facilities.
How to craft Fertilizer at the Forge of the Sky
- Fertilizer crafting is handled at the Forge of the Sky facility.
- Interact with the Forge of the Sky crafting interface.
- Select the Fertilizer recipe from the unlocked crafting list.
- Provide the required materials: 1 Liquid Xiranite and 1 Burdo-Muck.
- Confirm crafting to produce Fertilizer.
The process is straightforward, but maintaining a healthy stock of Burdo-Muck is the limiting factor.
Fertilizer crafting materials
| Item | Quantity Required | Source |
|---|---|---|
| Liquid Xiranite | 1 | Resource acquisition and processing |
| Burdo-Muck | 1 | Dropped by Burdenbeasts |
| Output | 1 Fertilizer | Used for Eco-Plots |
How Fertilizer improves Eco-Plot output
Fertilizer enhances your Eco-Plot productivity by increasing yield efficiency. While not mandatory for progression, it significantly accelerates resource farming cycles. If you are aiming to complete Crafting Manual entries early, using Fertilizer consistently can reduce time investment.
Eco-Plots benefit most when you are cultivating high-value crops or materials tied to mid-game crafting. The boost becomes especially noticeable when stacked over multiple planting cycles.
Why Burdo-Muck and Fertilizers matter at all
Although Fertilizer is technically optional, its impact on long-term efficiency is substantial. Crafting Manual completion often requires resource loops that benefit directly from higher Eco-Plot yield. By farming Burdenbeasts regularly, you maintain control over this progression bottleneck rather than relying on passive accumulation.
In short, Burdenbeast farming is not about immediate power spikes. It is about smoothing your economic curve in Arknights: Endfield.
If you want to optimize your farming systems and reduce grind later, Burdenbeast routes in Jingyu Valley are worth integrating into your regular exploration loops. Secure the Fertilizer recipe from Pu Yuan, maintain a steady Burdo-Muck supply, and leverage the Forge of the Sky to keep your Eco-Plots running at peak efficiency.
