## \*TL;DR - Key Points

* \* **Server codes are NOT compatible** \-- NA/EU codes will not work on Asia servers and vice versa
* \* **Some Asia codes missing** \-- Community ports needed; join Discord to help
* \* **V4 Carbon Farm** \-- Add 30/min carbon for factory-grade depot orders
* \* **Wuling Production Modes** \-- 12 Batteries/min OR 6 Batteries + 3 Components/min
* \* **All blueprints from** \-- Arknights: Endfield Official Discord server

**Gearing your endgame DPS too?**Once your Wuling factory is humming, plan your T4 substats with the[Artificing Planner](https://endfieldhub.org/tools/artificing-planner)it ranks every Good Match fodder by craft cost so you spend Wuling Stock Bills on the cheapest piece, not the flashiest one.

## Technical Tips & Notes

### V4 Carbon Farm Addition

You can add a simple carbon farm in V4 to complete factory-grade depot orders if your Buck Capsule \[A\]/HC Valley Battery stockpile is low. Just **30/min** is enough for all three depots.

### Code Discrepancies

Some blueprints may have discrepancies between NA/EU and Asia codes, and some may not have Asia codes at all. If you'd like to port or fix a code, join the **Arknights: Endfield Official Discord** server and contribute to community efforts.

### Server Compatibility Warning

**Blueprint codes are locked to their specific regions.** NA/EU codes will not work on Asia servers and vice versa. Always verify you're using the correct code for your server region before importing.

### Questions & Support

Feel free to ask questions in the comments below or join the official Arknights: Endfield Discord server for real-time help from the blueprint creators and community members.

## Frequently Asked Questions

### Can I use NA/EU blueprint codes on Asia servers?

No. Blueprint codes are locked to their specific regions. NA/EU codes will not work on Asia servers and vice versa. Always use the code that matches your server region.

### Why are some Asia codes missing?

Some blueprints haven't been ported to Asia servers yet. If you'd like to help port or fix Asia codes, join the official Arknights: Endfield Discord server and contribute to the community efforts.

### What's the difference between V4 Main PAC and Sub-PAC?

The Main PAC handles primary production chains while Sub-PACs are auxiliary production areas that support the main factory. Sub-PACs typically handle overflow production or specialized items.

### Can I modify these blueprints for my needs?

Yes! These blueprints are community-sourced and meant to be adapted. Feel free to adjust production lines, add farms, or reconfigure layouts to match your resource availability and goals.

### How do I add a carbon farm to the V4 blueprint?

Add a simple carbon farm producing 30/min to complete factory-grade depot orders if your Buck Capsule \[A\]/HC Valley Battery stockpile is low. This is enough to supply all three depots.
