# Lootboxes

Lootboxes in BattleMancers ecosystem is the main reward for winning a PvP match. These lootboxes are NFTs with ERC-1155 standard. The reason why we preferred the 1155 standard instead of 721 is because of the gas fees on Ethereum Network. ERC-1155 allows NFTs to be stacked on each other; in other words, they can be minted or traded in bulk. Thus, players would not have to pay a gas fee each time they want to sell or buy a lootbox, which would make the on-chain transactions a lot more user friendly and affordable. NFTs with ERC-1155 standard is also tradable on Opensea just like ERC-721.&#x20;

### Lootbox Tiers

There are four tiers of Lootboxes that can be earned from the game. These lootboxes are rewarded according to season level of players:

Higher tier lootboxes yield much greater rewards both in BTMC, Cards, and consumable items. With higher tiers, rewards are not only increased in quantity but also in quality.&#x20;

Accessing higher levels is only possible through Card Fusion mechanic of the game. Read [Experience Model](https://battle-mancers.gitbook.io/untitled/game-mechanics/experience-model) section for further details.

### Lootbox Rewards

There are tree type of rewards from lootboxes:\
(1) [BattleMancer Coin](https://battle-mancers.gitbook.io/untitled/assets/battlemancer-coin-btmc) (BTMC)\
(2) [Cards](https://battle-mancers.gitbook.io/untitled/assets/cards)\
(3) [Consumable items](https://battle-mancers.gitbook.io/untitled/assets/consumable-items)

Lootboxes (ERC-1155) and BTMC (ERC-20) can be minted to blockchain, but rest of the rewards can only be used in-game. We have plans to allow the minting of Cards and Consumable items at a later stage of the project.&#x20;

All rewards can be acquired by free-to-play or play-to-earn players alike; however, they can only be minted to blockchain by the holders of [BattleMancers Genesis](https://battle-mancers.gitbook.io/untitled/assets/battlemancers-genesis) collection. Those who does not possess an NFT would need to buy or rent one before being able to mint their rewards
