# Production and Development Cycle
Every EtherForge factory starts at Level 1, operating at its default refining and production speed. This is the foundation stage, where machines begin functioning and generate the first products in the bio-production chain.
## Machine Types
* **ValorForge → Produces Heroes**\
**MonstroForge → Produces Monsters**
| Level | Upgrade Cost ($USDC) | Production Output ($ETHER) |
|---|
| 1 | 0 | 10 |
| 2 | 10 | 50 |
| 3 | 20 | 200 |
| 4 | 30 | 350 |
| 5 | 40 | 500 |
* **ProtoForge (released on Jan 25th, 2026)**
| Level | Upgrade Cost ($USDC) | Production Output ($ETHER) |
|---|
| 1 | 0 | 2 |
| 2 | 2 | 10 |
| 3 | 4 | 40 |
| 4 | 6 | 70 |
| 5 | 8 | 100 |
* **CoreForge (released on Jan 25th, 2026)**
| Level | Upgrade Cost ($USDC) | Production Output ($ETHER) |
| :---: | :------------------: | :------------------------: |
| 1 | 0 | 4 |
| 2 | 4 | 20 |
| 3 | 8 | 80 |
| 4 | 12 | 140 |
| 5 | 16 | 200 |

*Higher levels yield greater **$ETHER** production efficiency and improve long-term **$GENESIS** generation once machines reach their final phase.*

## Refining Cycle
Once activated, a machine enters a 12-hour refining cycle. At the end of each cycle, it produces a Bio-Core Cocoon an unrefined energy vessel containing the essence of life.
Players must manually open the cocoon to initiate the lifeform inside, and the outcome depends on the type of machine owned:
* ValorForge creates a Hero
* MonstroForge creates a Monster
* ProtoForge and CoreForge have 50/50 chance to hatch a Hero or Monster
## Lifeform Rarity
The rarity of each lifeform: **Common, Rare, or Legendary** is determined randomly, ensuring every cocoon opening delivers both excitement and unique value.
## Machine Lifecycle
Each machines can refine only one egg cocoon throughout its entire lifetime. After that, the machine permanently switches to its $ETHER production role, continuously generating energy on a daily basis.
This design turns every machine into a limited production asset, ensuring the scarcity of creatures and maintaining economic balance within the world of EtherForge.
