Magic find diminishing returns

Magic find enjoys diminishing returns, in terms of generating Rares, Sets, and Uniques, as the amount of magic find increases. This is a balancing effect; in v1.07 short after the Expansion was released there were no diminishing returns, and it was possible to get all set or unique drops (if sets/uniques existed for the item type in question). This was changed with the introduction of diminishing returns, and as of v1.11 they function as shown in the following table.

A higher % of magic find from your character's equipment will always make more of the items that are dropped be at least magical. Higher magic find % will make more of the items that are dropped generate as unique, set, or rare, but the added benefit decreases with more points in the bonus.
