Just as it is in Dungeons & Dragons, the magic items in Baldur's Gate 3 are organized into rarity levels to designate their strength, ranging from uncommon, to rare, to very rare, all the way up to legendary. Generally, an item's usefulness can be determined by comparing its rarity to another of the same type; for instance, a +2 rare longsword is a straightforward upgrade to a +1 uncommon variant.
