Legendary Magic Items
Rarity
Each magic item has a rarity: Common , Uncommon , Rare , Very Rare, Legendary, or even Artifact. Common Magic Items, such as a Healing Potions, are the most plentiful. Some legendary items, such as the apparatus of Kwalish, are unique. The game assumes that the secrets of creating the most powerful items arose centuries ago and were then gradually lost as a result of wars, cataclysms, and mishaps. Even uncommon items can't be easily created. Thus, many magic items are well-preserved antiquities.
Rarity provides a rough measure of an item's power relative to other magic items. Rarity can also help set prices for them. The value of an individual magic item can be based on its rarity. The value of a consumable item, such as a Potion or scroll, is typically half the value of a permanent item of the same rarity.
