There’s a variety of ways to gear up your character in Diablo 3: Reaper of Souls. The introduction of Adventure Mode, which includes Bounties, allows players to gear up by completing various quests throughout each act in the game. By completing five Bounties in an act, players will receive a Horadric Cache that has the potential to include Legendary items unique to the Horadric Cache, as well as regular Legendary items.
Blizzard has announced a slight change to the mechanics of the Horadric Cache, stating that in a future update, there will be the possibility that Torment-only Legendary items, such as class set items, will have a chance to drop from Horadric Caches.
That’s the first change. The second change is that they’ll be increasing the chance for Legendary items to drop from the cache in general, so you won’t have to go through dozens of Horadric Caches without a single Legendary drop ever again.
Here’s Community Manager Grimiku on the subject:
As a heads up, we’re looking to make two changes to Horadric Caches. The first change is to allow the caches to drop Torment-only Legendary items. The second is to increase the chance that you’ll find a Legendary item in Horadric Caches, including Act-specific Legendaries like the Royal Ring of Grandeur, based on the Torment difficulty. What this means is that Horadric Caches earned in Torment I+ will be able to drop Torment restricted Legendary items, and caches earned in Torment II+ will have a scaling bonus for dropping Legendary items (which includes those items only found in a cache).
