# Digital Vehicle

#### Attributes

1. **Eco-driving:**\
   The higher the Eco-driving attribute, the more efficient Fuel Usage (KM/Fuel) will be, meaning a user will be able to travel (and earn) over a longer distance per fuel percentage point
2. **Efficiency:**\
   The higher the Efficiency attribute, the more BYL a player is able to earn for each KM travelled
3. **Luck:**\
   The Luck attribute determines the frequency of Gift Box drops for players
4. **Tuning:**\
   The higher the Tuning attribute, the lower the rate of depreciation for your Vehicle per fuel percentage point

#### Levelling

Users are able to level up their Digital Vehicle by spending BYL. Attribute points will be gained at each level for users to allocate. The number of additional attribute points is based on rarity tiers and reflected in the table below. The cost to level progressively increases with each level and rarity tiers.

| Rarity   | Attribute point/level up |
| -------- | ------------------------ |
| Common   | 4                        |
| Uncommon | 6                        |
| Rare     | 8                        |

#### Depreciation

Depreciation measures the wear and tear of your Digital Vehicle. Each Vehicle has a Depreciation meter which decreases according to distance travelled.

When Depreciation drops below 50/100, the effective Efficiency stat drops to 50%, meaning your earnings are halved. When Depreciation drops below 20/100, the effective Efficiency stat drops to 10%, meaning your earnings are 1/10th.

The Tuning stat affects the rate of Depreciation. A higher Tuning will result in lower Depreciation decay. Repair costs for depreciation increases with level and rarity of Vehicles.

#### Rarities (Only applicable to Digital Vehicles)

The table below shows the three different rarity tiers of Digital Vehicles. When a Digital Vehicle is newly produced, each Vehicle's base attributes will be randomly assigned within the range shown below.

| Vehicle Rarity | Min Attribute | Max Attribute |
| -------------- | ------------- | ------------- |
| Common         | 2             | 8             |
| Uncommon       | 6             | 12            |
| Rare           | 10            | 16            |

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://booost-1.gitbook.io/booost-whitepaper/drive-mode/digital-vehicle.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
