Item rarities in Blox Fruits are a classification system shown through colored text tags, used to indicate an item’s value, strength, and rarity of obtainment, and they apply to a wide range of items including Blox Fruits, swords, guns, accessories, materials, scrolls, fishing rods, and paid items; for weapons, rarity typically reflects both how hard the item is to get and how powerful it is, while for materials it determines the types of crafting recipes they are used in, with higher-tier items generally requiring rarer components, and overall the system consists of five main tiers that progressively increase in rarity and strength, along with a sixth tier (Premium) whose value can vary depending on the item.
