Anatomy Science Club is a collection of 8,000 OG anatomical mortals dissected through their organs. This collection is the predecessor of the ASAC and MASAC NFT collections. A process led by Dr. Sloki called the Eternal Inferno brought these mortals to life.

For you to get this, you have to get 1 ASAC and 2 MASAC with the same rarity, and then burn then at https://anatomyscience.club.

2 Common MASAC = 1 Common OG ASC 2 Uncommon MASAC = 1 Uncommon OG ASC 2 Rare MASAC = 1 Rare OG ASC 2 Epic MASAC = 1 Epic OG ASC
