Items in Path of Exile 2 come in four rarities: Normal (White) items have no modifiers. Magic (Blue) items have 1-2 modifiers (prefixes/suffixes). Rare (Yellow) items have 3-6 modifiers, making them the backbone of most builds. Unique (Orange) items have fixed, powerful modifiers that often enable specific build archetypes but can also have drawbacks. Always identify rare items, as they can be significant upgrades or valuable for crafting.
