Diablo 3 is still being supported with new content four years after release, so while the next update might be mostly predictable, it's still great that it's being supported at the very least. Anyway, you're a Diablo player - new loot should be all you need.
There's more treasure to be found in our list of the best RPGs.
As you'd expect, the new update adds new difficulty levels, Torment XI–XIII, and fills those with tougher enemies and better loot. The cycle never ends.
Patch 2.4.2 also brings updates to many Legendary and Set Items, as well as adding a few new items and Legendary powers. Check the PTR patch notes for all the details.
The UI is getting a few tweaks, too. Blizzard are adding unique pylon minimap icons to Nephalem Rifts and Greater Rifts, and a unique icon for the Menagerist Treasure Goblin. On top of that, if you're a fan of taking screens, there will also be a hotkey for hiding all that screen clutter.
Lastly, the patch will be sweetening Adventure Mode rewards, starting with Nephalem Rifts. You’re now guaranteed a Greater Rift Key when completing any Rift, with a chance to get a second (or even a third) key as you increase the game’s difficulty.
Additionally, drop rates have been adjusted for Infernal Machines, with a 100% drop chance in Torment IV, and an increasing chance for a second machine to drop as you go up in difficulty.
