Blizzard has cooked up a brand new Reaper of Souls gameplay trailer. It shows off the Crusader, Adventure Mode, Nephalem Rifts, new character skills, Paragon Points, and other cool stuff that will be completely fresh and new to you… unless you were conscious during the beta. In which case it’s less new, but no less desirable.
Spoilers! The very end of the vid shows a few seconds of the battle against Malthael, so if you want to see nothing of that until you face it for real, stop watching around the 1:15 mark.
