There’s quite a list to hoe through, but as indicated earlier, the Monster Power system (similar to Diablo 2′s /players 8) is in as well as the Infernal Machine (similar to the old uber-monsters).
Other noteworthy entries include:
- In Inferno, resplendant chests now drop loot in a similar way to Elites (scaling with Nephalem Valor), and will also grant a stack of Nephalem Valor when opened.
- Followers and pets will no longer attack idle monsters unless they are within 10 yards of the player
- Item affixes are now tied to the level of the monster killed and not the item’s level.
There are a raft of other changes. Head on over and give it a look.
UPDATE: Updated patchnotes here.
