# Rarity and Traits

### Rarity

It is important to note that the rarity of a Hopper is decoupled from that of its attributes that are used in Adventures. Instead, the rarity of a Hopper is determined by the cumulative collection of specific traits a Hopper has.

Hopper rarity will have scores associated with them. The higher the score, the rarer the NFT is based on the combined scores of all traits. 

Hoppers will follow the following rarity structure.

Note that some Hoppers will have traits that are extremely rare but because that Hopper may have other more common traits, then Hopper's rarity score may not be that high.
