Blizzard Entertainment deployed a new Diablo III: Reaper of Souls beta patch (build 21390).
Among the most important changes is the availability of all the materials to build the Infernal Machine (level 70) and thus the Jeweler is able to craft the Hellfire Ring level 70 — as well as Adventure Mode, Crafting, Cursed Chests and Class changes. — PTR Patch Notes are also available.
