Every account has its own Mana count, influenced by the number and rarity of Backpack NFTs. Mana is used when answering the questions on the Quiz Module.
Users can participate without additional cost in the Ladder ranking while answering questions on the Quiz Module. But if users want to earn direct rewards, they need to have a Backpack NFT in their inventory. They can decide to buy directly from the marketplace or rent a Backpack NFT.
Renting lowers the barrier for the users who cannot afford a Backpack NFT. To do so, the Backpack must be at least at level 30. Each renting contract is valid for one Epoch. After one Epoch, the rewards are distributed between the owner and the renter based on the contract details.
