NFTs in Castle Overlord can be purchased (minted) through booster packs. Each booster pack may contain a single NFT unit or a bundle of multiple units. A booster pack’s theme will also determine the unit type it contains and the faction.
Here are a few examples of booster packs and their contents:
Steampunk Trooper Pack. Contains 1 trooper from the Steampunk faction.
Cyber Samurai Trooper Bundle. Contains 5 troopers from the Cyber Samurai faction.
Single Color Military Trooper Pack. Contains 1 trooper from the Military faction with same-colored unit parts.
Units that players gain through booster packs consist of randomized parts. The randomizer affects the following aspects of a part:
Part appearance. This determines the 3D mesh of a part installed in a unit.
Type variant. Some parts have type variants, such as the Steampunk faction’s weapon part which may consist of a punch-type weapon or a smash-type weapon.
Part rarity. This determines the quality of a part, whether it’s common, rare or legendary. Higher rarity results in a higher stat. Legendary parts are only obtainable as long as the stock lasts.
Appearance variant. Once the 3D mesh has been determined, this calculation is executed to apply the material (color and texture) to the mesh. There are 5 available variants for each 3D mesh.
