As introduced in the previous chapter, when minting a Dragobit, a certain amount of the specified ERC-20 token will be attached to it. The amount of the token may vary per Dragobit, depending on the on-chain token price at the time of the transaction. When a Dragobit is transferred, access to the attached tokens is also transferred. The token is held in a separate smart contract for each Dragobit, known as the "**Dragobit Vault**".

## Mint Boost Vault

When minting a Dragobit, the minter has the chance to get a boosted amount of the attached ERC-20 token which comes from a special vault that is owned by the Dragobits contract itself. The chance probability may vary per [deployment](https://docs.dragobits.com/deployments).

## Claiming

Only the owner of a Dragobit can access its vault. A vault can hold not only tokens but also ETH (native gas). If a Dragobit owner wishes to withdraw tokens or ETH from the vault, this can be done anytime when the Dragobit is not actively engaged in [gameplay](https://docs.dragobits.com/game/arena).

However, to claim from the vault, the Dragobit NFT must be burned. This mechanic ensures that once a major player chooses to exit, space is made for new players. For instance, if the exiting player owned a Dragobit with very high strength, it would have been particularly powerful in gameplay.&#x20;

Additionally, when claiming from the vault, a certain percentage of the tokens will remain in the vault to be indirectly burned. This serves as spam protection to prevent players from circumventing the [reroll](https://docs.dragobits.com/getting-started/rerolls) fee.
