Item Rarity increases the chance for found items to be Magic, Rare and Unique. It also increases the chance for found Magic and Rare items to have Tiers.

Unlike Item Rarity on monsters or Maps, Item Rarity from the Player has no effect on the types of Currency and amount of Gold dropped.

Kills from Minions use the player's Item Rarity instead of their own. Kills from hired Mercenaries use their own Item Rarity instead of the player's.
