The NFT Mint
Spellbook NFTs will not be sold by the management other than the total number sold at the public sale. However, holders of two or more prophet NFTs can generate new spellbook NFTs (called minting) by

Minting Cost

You will need $NDT to mint. The cost required depends on the class and mint score of each prophet NFT. $NDT cost depends on two factors a. Class of original two NFTs (NFT1 and NFT2) b. cumulative mint frequency=score of each NFTs. Each NFT can mint up to 6 times.
$NDT cost of minting a new NFT: $NDT cost depends on two factors a. Class of original two NFTs (NFT1 and NFT2) b. cumulative mint frequency of each NFTs. The $NDT cost is given by
Mint Cost=500×CCM1CCM2MSM1MSM2\text{Mint Cost} = 500 \times CCM_{1}*CCM_{2}*MSM_{1}*MSM_{2}
where
CCM1,2CCM_{1,2}
are class cost multiplier and
MSM1,2MSM_{1,2}
are Mint Score multiplier for NFT1, NFT2, respectively.
Class Cost multiplier
=(Class Total Earnig PowerClass Initial Earning Power)1/8×Class factor=\left( \frac{\text{Class Total Earnig Power}}{\text{Class Initial Earning Power}} \right)^{1/8} \times \text{Class factor}
where Class Earning power is the summation of NFT earning power (= 500 × Class NDT Multiplier) for all prophet NFT in a given class (”total” means current all NFT issued, and “initial” means initial 3400 NFT at the launch time). Class factor is given below.

Probability of classes

Minting will result in Spellbook NFTs. Upon reveals, these spellbook NFTs become prophet NFTs. Probabilities for acquiring prophet NFTs are the following.

Reference Table for Mint Cost

For convenience, here we give the minting cost table for each classes.
To make the minting cost of NFT easier, we provide a reference table here. Since many factors go into the calculations of minting cost, here we assumed (unrealistic assumption but again, this is only for reference purpose) that 1. all prophet NFTs are Level 1 2. all spellbook NFTs are changed into prophet NFTs 2. Distribution of prophet NFTs stays the same as the initial distribution (ex 80% is Junior). In this assumption, the following is the minting cost for Junior * Junior/Senior * Senior minting where both NFTs have mint score =0.

About the mint limit of each prophet NFT

One prophet can only mint up to 6 times.

Cooldown

Each NFT has cooldown period after minting, and it cannot mint another NFT during the cooldown period. Cooldown period is 1 day = 24 hours.
