Item or Monster rarity can be Normal (grey), Magic (blue), Rare (yellow) or Unique (brown). As a general rule, monsters increase in difficulty depending on their Rarity.

Jewels are items that can be socketed into Jewel Sockets on the Passive Skill Tree to grant bonuses. Basic Jewels simply grant you the listed stats, while some other kinds of Jewel can have more complicated effects, such as modifying other Passive Skills within a certain radius.

Some methods of item crafting guarantee that a specific Modifier will be crafted onto the item. An item can only have one Crafted Modifier, but they otherwise behave identically to other Modifiers. Crafted Modifiers are displayed in a lighter blue colour than regular Modifiers.
