The level 23 version of this set is Cain's Fate.
The set includes four items, three of which are required to complete it.
- +8% increased attack speed, +50% better chance of finding magical items and +50% experience (+5% at level 70) (2 items)
- When a Greater Rift Keystone drops, there is a 25% chance for an extra one to drop (3 items)
The experience/magic find property, while may sound useful, is actually not worth taking item slots in the endgame: the experience bonus is not multiplicative with the one for increased difficulty, and only 10% of the bearer's total Magic Find truly applies to Legendary/Set items.
