# Part Purity

Every **AXIS ARC-Forge** will be randomly assigned a unique **Purity Range**, which are the only possible **Purity** values that an Alloy Part will be assigned once revealed.

Along with ARC-Forge **Classes**, there are also ARC-Forge **Models** within each class.

| ARC-Forge Type | ARC-Forge Class | # of Models |
| -------------- | --------------- | ----------- |
| AXIS-REC       | Class 1         | 7           |
| AXIS-H         | Class 2         | 5           |
| AXIS-S         | Class 3         | 5           |
| AXIS-PRO       | Class 4         | 5           |
| AXIS-E9        | Class 5         | 5           |

The **Purity Range** improves with each higher Class ARC and with each higher **Model** number.

> For example, an **AXIS-REC Model 7** has a better **Purity Range** than an **AXIS-REC Model 3** but an **AXIS-H Model 1** has a better range than both of these (Class 1 vs. Class 2).

These **Purity Ranges** are randomly assigned to every ARC-Forge when minted. They are assigned from within a given range per Model, with the lower end of the range being its own range, so that each ARC is unique:

| ARC-Forge Type | Model 1      | Model 2      | Model 3      | Model 4      | Model 5      | Model 6     | Model 7     |
| -------------- | ------------ | ------------ | ------------ | ------------ | ------------ | ----------- | ----------- |
| AXIS-REC       | (1-10) - 30  | (1-10) - 35  | (1-10) - 40  | (1-10) - 45  | (1-10) - 46  | (1-10) - 47 | (1-10) - 50 |
| AXIS-H         | (5-20) - 50  | (5-20) - 55  | (5-20) - 60  | (5-20) - 62  | (5-20) - 65  | N/A         | N/A         |
| AXIS-S         | (10-30) - 70 | (10-30) - 75 | (10-30) - 76 | (10-30) - 77 | (15-40) - 77 | N/A         | N/A         |
| AXIS-PRO       | (15-50) - 78 | (15-50) - 79 | (15-50) - 80 | (15-50) - 81 | (15-50) - 82 | N/A         | N/A         |
| AXIS-E9        | (30-60) - 83 | (30-60) - 84 | (30-60) - 85 | (30-60) - 86 | (30-60) - 87 | N/A         | N/A         |

> In other words, the range of an **AXIS-REC Model 1** is always maxed at 30 but can be as low as 1 or ideally as low as 10. A set of these **Model 1** AXIS-REC ARC-Forges might look like this:
>
> **Purity Range**: 3-30
>
> **Purity Range**: 9-30
>
> **Purity Range**: 10-30
>
> i.e. the above ARC-Forges cannot make parts with a **Part Purity** that is over **30** or under their randomly assigned lower ends, which is 3, 9 and 10 respectively.

*Note that all **Purity Ranges** can be improved through* [***Enhance Upgrades***](https://alloy-space.gitbook.io/alloy-space/upgrade-parts/arcforge-upgrades)*, which are discussed in a later section.*

{% hint style="warning" %}
The **Purity** value assigned to a processed **Alloy Part** will start to degrade very slowly 5 days after a part has been processed. Parts can be listed for sale and purchased by other players, helping players secure **Alloy Constructs** much faster. ***Alloy Constructs** do not degrade.*
{% endhint %}

{% hint style="info" %}
The best performing ARC-Forge that can be minted is an **AXIS-E9 Model 5**, but of *those* minted the best will be the one with the better random **Purity Range**, which maxes out at **60-87** (before any **Enhance Upgrades** or **Contract Bonus**).
