# Mining
Tomo Cat makes mining so chill that it literally happens when the cat is taking his cooldown nap. Profits can be boosted in the Profile section via leveling and with the help of specialized mining items.
**Items**
As your Tomo’s level increases, its mining base grows. To boost this process, specific items are needed. These items can be purchased and upgraded in the shop.
When you buy and upgrade multiple items, their effects stack. For example, if you have both a blanket and pajamas, their mining bonuses combine, giving you a total boost.
Each item can be upgraded up to 100 levels using coins, increasing your mining capacity.
**Premium Items**
In addition to regular items, there are premium items available for stars in Telegram. These premium items have 50 levels and offer special bonuses. For instance, the "Night Sky" item provides 50 coins per hour at the 1st level and a lamp offers 16 per hour. You can also find various skins for each item in the shop.

## 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://tomocat.gitbook.io/bbsaikjnjdsd/core-features/mining.md?ask=&goal=
```
`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.
