Stores magma-refined Pyrestone, sealed in obsidian containers.
| Level | HP | Max Pyrestone Storage | Energy Containment Efficiency | Upgrade Time | Appearance Changes |
|---|---|---|---|---|---|
| 1 | 1200 | 100,000 | Basic | 30m | A small reinforced chamber, glowing with molten energy, with steam vents. |
| 2 | 1800 | 250,000 | Improved | 1h | The reservoir expands, with visible Pyrestone flows and reinforced iron plating. |
| 3 | 2500 | 500,000 | Enhanced | 2h | Magma conduits extend outward, increasing energy containment efficiency. |
| 4 | 3500 | 750,000 | High Efficiency | 4h | Heavy obsidian plating, larger containment tanks, and glowing core vents. |
| 5 | 4500 | 1,200,000 | Maximum Stability | 8h | A colossal furnace-like structure, with raging magma pools and intricate industrial mechanisms. |
Upgrade Breakdown:
HP Increases as the reservoir becomes more fortified.
Storage Capacity Expands, allowing larger reserves of Pyrestone to be held.
Energy Containment Efficiency Improves, ensuring less energy loss and more stable storage.
Visual Changes Add Complexity, with larger magma conduits, heavier plating, and advanced containment technology.
