# 4.1 NFTs

The NFTs will have 2 separate upgradable elements.

-Tiers\
-Rarities\
\
Tiers: Each of the NFTs can be bought/upgraded to a maximum of Lvl 5. The cap will be increased level by level.\
\
Rarities: NFTs can be minted or bought in 3 different rarities. 

-Decayed\
-New\
-Futuristic\
\
Futuristic is the rarest of all and has the lowest chance to be minted. There won't be many available at the beginning. For example if you have a decayed one and collect all the components of the “old” one the rarity can be upgraded to “refurbished”
