Does “x% better chance to find magical items” affect rare and legendary drop probabilities?

Question

I'm wondering how much effort to put into looking for items that have "x% better chance to find magical items". The description says "magical". Does that mean only magical, or does it increase the chance to find rare and legendary items as well?

Answer 1

YES

A magic item is any object that has magical powers inherent in it. Those are:

• Blues (Magic)
• Yellow (Rare)
• Orange (Legendary)
• Green (Tier/Set)

Magic Find in Diablo III

Magic Find increases the odds for found items (from monsters or objects) to be "higher quality". Higher quality items are more likely to be magical, rare, set, or legendary, with different odds for each type of item depending on the Monster Level dropping the item and the player's Magic Find percentage. Magic Find doesn't make items with higher item level to drop since monsters have a set of items they're capable of dropping (eg. the highest tier of items will only drop from monsters with Monster Level 63) nor does it increase the quantity of items dropped.
