- Players who avoid death in a Greater Rift will be rewarded with one additional chance to upgrade their Legendary Gems!
- Greater Rift monster distribution has been spread out more evenly, and the size of each floor is now more consistent. On average, a rift should take between two to four floors to clear
- Leaping enemies like Winged Assassins, Punishers, Lacuni Huntresses, and Burrowing Leapers can now be slain in mid-air
- Enemies with unattackable phases like Sandsharks, Snakemen, and Rockworms will spend less time avoiding you
- Enemy affixes have been tweaked, including updates to Shielding, Reflects Damage, and Electrified. In addition, an entirely new affix, Juggernaut, is entering the fray.
edit: non-english sources have said the patch is Wednesday.
