## New Materials & Products

### Dietsalite Component

| Property  | Details                                    |
| --------- | ------------------------------------------ |
| Full Name | Bicolor-Adaptive Single-Use Xiranite Mould |
| Quality   | Gold-tier gear material                    |
| Source    | Produced from Dietsalite Solution          |
| Use Case  | Crafting high-quality operator gear        |

**Note:** Can create various gold-quality gear pieces beyond shown examples.

### Heavy Xiranite

| Production | Requirements                 |
| ---------- | ---------------------------- |
| Facility   | Forge of the Sky             |
| Inputs     | Dietsalite + Dicium Effluent |
| Output     | Heavy Xiranite               |

**Applications:**

1. **Facility Repairs:** Special outpost maintenance
2. **Outpost Trading:** Exchange at trading terminals
3. **Gear Crafting:** Combine with Dietsalite Part → Dietsalite Component
4. **Blight Control:** Process into Liquid Heavy Xiranite to neutralize Active Blight

## Forge Capacity Expansion

### Post-Update Limits

| Region          | Previous | New Maximum              |
| --------------- | -------- | ------------------------ |
| Wuling (base)   | 4        | **6** Forges of the Sky  |
| Titanium Area\* | 4        | **12** Forges of the Sky |

\*Titanium Area unlocks after completing AIC technologies research in Wuling AIC facilities

### Strategic Impact

* **Increased throughput:** 50% more Forge capacity in base Wuling
* **Endgame scaling:** 3x capacity after Titanium Area unlock
* **Xiranite production:** Scale up Heavy Xiranite for trading/repairs
* **Gear crafting:** Support multiple Dietsalite Component production lines

---

## Production Chain Examples

### Dietsalite Component Chain

```
Precipitation Acid → [Purification Unit] → Dietsalite Solution
Dietsalite Solution → [Processing] → Dietsalite Part
Heavy Xiranite + Dietsalite Part → Dietsalite Component (Gold Gear)
```

### Heavy Xiranite Loop

```
Dietsalite + Dicium Effluent → [Forge of the Sky] → Heavy Xiranite
Heavy Xiranite → [Optional] → Liquid Heavy Xiranite (Blight neutralization)
Heavy Xiranite → Outpost Trading → Stock Bills
```

---

## Strategic Recommendations

### Early Wuling Setup

1. Build 2-3 Acid Resistant Pumps Mk II near Aggeloid spawn zones
2. Install Conduit Manifolds for flexible fluid routing
3. Prioritize Purification Unit for Dietsalite production
4. Expand Forge of the Sky to 6 units ASAP

### Mid-Game Optimization

1. Complete AIC research to unlock Titanium Area
2. Expand Forges to 12 units for mass production
3. Set up Heavy Xiranite trading loop for Stock Bills
4. Maintain Liquid Heavy Xiranite stockpile for Blight events

### Late-Game Goals

* Full Dietsalite Component gear sets for main team
* Automated Heavy Xiranite export for passive income
* Redundant Precipitation Acid extraction infrastructure

---

## Summary

Version 1.2 significantly expands Wuling’s AIC Factory capabilities with:

* **New resource:** Precipitation Acid extraction
* **New facilities:** Purification Unit, upgraded Crucible
* **New products:** Heavy Xiranite, Dietsalite Components
* **Capacity boost:** 6→12 Forges with research progression

These updates enable advanced production chains, gold-tier gear crafting, and new trading opportunities for endgame factory optimization.
